Description: PROTEINS HAVING LECITHIN-CHOLESTEROL ACYLTRANSFERASE-LIKE ACTIVITY, THEIR PRODUCTION AND USE Technical Field 5 The present invention relates to a novel protein having a lecithin-cholesterol acyltransferase-like activity etc. and a DNA coding for the protein. Background Art 10 Cholesterol is an important lipid constituting the animal cell membrane and defining its character. Moreover, it is a precursor of steroid hormones, thus being a substance essential to animal life. However, due to the recent changes in dietary habit and ecology, 15 arteriosclerosis and other adult diseases arising from pathological intracellular accumulation of cholesterol are now presenting a serious problem so that elucidation of the mechanisms of cholesterol metabolism in the body is being awaited. 20 In the efflux of cholesterol from the peripheral cells, high density lipoprotein (hereinafter sometimes referred to briefly as HDL) is suspected to play a cardinal role and this assumption has been supported by the epidemiologic finding of an inverse correlation 25 between risk for coronary artery disease and plasma HDL levels and the experimental finding that HDL in culture medium stimulates cholesterol efflux from cells and decreases the intracellular concentration of cholesterol (Journal of Lipid Research, 37 . , 2473, 30 1996). In the reverse cholesterol transport system, lecithin-cholesterol acyltransferase (hereinafter sometimes referred to briefly as LCAT) is involved to a significant extent. LCAT transfers the β-acyl group (fatty acid) of 35 lecithin (phosphatidylcholine) to the 3β-0H group of cholesterol, so that it consumes the equivalent moles of lecithin and unesterified cholesterol and produces the equivalent moles of cholesteryl ester and lysolecithin (Journal of Lipid Research, 9., 155, 1968). In the circulation, most of LCAT exists in HDL to show activity and a portion of the cholesteryl ester produced in the HDL is taken up and metabolized in the liver, while another portion of the ester migrates into the nonpolar core of the HDL particle to give rise to a mature HDL rich in cholesteryl esters . Owing to the concentration gradient resulting from the consumption of unesterified cholesterol in HDL, the HDL continuously absorbs cholesterol from the other cell membranes. In this manner, LCAT together with HDL is in charge of the reverse cholesterol transport from peripheral tissues to the liver, thus contributing to the anti-atherosclerotic action of HDL (Biochimica et Biophysica Acta, 1084, 205, 1991). In familial LCAT deficiency which is an inheritable disease, the reverse cholesterol transport system is lacking so that characteristic tissue damages occur from deposits of cholesterol, leading to coroneal opacity, hemolytic anemia associated with a morphological abnormality of erythrocytes , and proteinuria and renal failure due to kidney impairment (Lancet, 388. 778, 1991). In addition to gene abnormalities, various illnesses involving plasma lipid abnormalities cause changes in LCAT activity. For example, LCAT activity is reportedly elevated by hypercalorism or in obesity and hypertriglyceridemia (Clinical Science, ___, 593, 1970) and decreased in malnutrition, abetalipoproteinemia, and Tangier disease . LCAT is a 416-residue polypeptide synthesized in the liver, and exists as a glycoprotein with a molecular mass of 59-68 KDa (Journal of Biological Chemistry, 254 , 7456, 1979). In the blood, most of LCAT exists in HDL and in the expression of its activity, Apo Al , the principal apoprotein of HDL, acts as the cofactor to stimulate LCAT activity (FEBS Letters, L5, 355, 1971). There exist a variety of mutant LCAT genes corresponding to the variation in enzyme defect and clinical picture in various cases of familial LCAT activity deficiency, and they are discharging significant functions in the metabolism of plasma lipoproteins . So far, only one kind of LCAT has been reported and the existence of any analogous protein having similar activity has not been predicted. Meanwhile, in arteriosclerosis, thrombus formation, and post-PTCA restenosis, abnormality of vascular tonus , enhancement of inflammatory reactions, and abnormality of the coagulation-fibrinolysis system, which stem from endothelial cell impairment, occur to cause a remodeling of the blood vessel with the proliferation and transformation of vascular smooth muscle cells as a cardinal pathological picture. The changes on the molecular level which occur in the course of formation of vascular lesions are now being understood in terms of a group of transcription factors controlling the expression of individual genes (Kurabayashi et al . , Modern Medicine, 5_2, 2340, 1997). In such a specifically expressed gene, there is a promoter (enhancer-repressor) sequence which functions only ad hoc and this promoter domain controls the transcription levels of the mRNA encoding the protein. Some of those promoters are known to be hormone- dependent or growth factor-dependent, and by utilizing them, several drug screening systems and transgenic animals have already been created and actually the systems used in the screening for drugs and the animals used in the analysis of vital functions. The present invention is for its object to provide a novel protein having LCAT and other activities, a precursor protein thereof, a partial peptide, a salt of either of them, a signal peptide, a DNA coding for said protein, precursor protein, partial peptide or signal peptide, a recombinant vector, a transformant , a method of producing said protein, a pharmaceutical composition comprising said protein or DNA, an antibody against said protein, a screening method/screening kit for a compound promoting or inhibiting the LCAT activity of said protein, a compound obtained by using said screening method, a pharmaceutical composition comprising said compound, a promoter for a novel protein having LCAT and other activities, a screening method/screening kit for a compound promoting or inhibiting the promoter activity, a compound obtained by using the screening method mentioned just above, and a pharmaceutical composition comprising the compound. The inventors of the present invention did intensive research to accomplish the above-mentioned objects and succeeded in cloning a cDNA having a novel nucleotide sequence from each of human heart-, human kidney-, and mouse kidney-derived cDNA libraries, and discovered that the protein encoded by those cDNA clones is a lecithin-cholesterol acyltransferase-like protein (hereinafter sometimes referred to as the LCAT- like protein) . The inventors further cloned the genomic DNA of said LCAT-like protein and by a promoter activity assay, found a promoter for said LCAT-like protein.

The starting compound with activated carboxyl groups includes the corresponding acid anhydride, azide, and active ester (e.g. esters with alcohols such as pentachlorophenol , 2 , 4 , 5-trichlorophenol , 2,4- dinitrophenol , cyanomethyl alcohol, p-nitrophenol , HONB, N-hydroxysuccinimide, N-hydroxyphthalimide, HOBt, etc.). The starting compound with activated amino groups includes the corresponding phosphorylamide . The method for removal of such protective groups includes catalytic reduction in a hydrogen stream in the presence of a catalyst (e.g. Pd black or Pd-on- carbon) , acid treatment with anhydrous hydrogen fluoride, methanesulfonic acid, trifluoromethanesulfonic acid, trifluoroacetic acid or a mixture thereof, treatment with a base such as diiso- propylethylamine, triethylamine, piperidine, piperazine or the like, and reduction with sodium metal in liquid ammonia. The above deprotection by treatment with acid is generally conducted at a temperature of about -20°C to 40 °C.

The 2 , 4-dinitrophenyl group used for protecting the imidazole group of histidine can be removed by treatment with thiophenol, and the formyl group used for protecting the indole group of tryptophan can be removed not only by said acid treatment in the presence of 1 , 2-ethanedithiol , 1,4-butanedithiol or the like as described hereinbefore, but also by alkali treatment with diluted sodium hydroxide solution, diluted liquid ammonia, or the like. The method for protecting any functional group that should not take part in the contemplated reaction, the protective group to be used for such protection, the method for eliminating the protective group, and the method for activating the functional group to be involved in the contemplated reaction can all be properly selected from among the known methods and groups . An alternative method for providing the protein in amide form typically comprises protecting the - carboxyl group of the C-terminal amino acid in the form of an amide, extending the peptide (protein) chain to a desired length towards the N-terminus, deprotecting the N-terminal α-amino acid of the resulting peptide chain selectively to provide an N-terminal-deprotected fragment, preparing a peptide (protein) fragment with its C-terminal carboxyl group selectively deprotected, and condensing the two fragments in a solvent such as the mixed solvent as mentioned above. The condensation reaction can be carried out in the same manner as described hereinbefore. After purification of the protected protein thus obtained by condensation, all the protective groups are eliminated by the procedures described hereinbefore to provide the contemplated protein in a crude form. This crude protein is purified by suitable known purification techniques and lyophilized to provide the desired protein amide. A method for providing the protein in an ester form comprises condensing the α-carboxyl group of the C-terminal amino acid with a suitable alcohol to prepare the corresponding ester and subjecting this ester to the same procedure as described for purification of the protein amide to provide the objective protein ester. The partial peptide, the signal peptide of the present invention or a salt thereof can be produced by per se known procedures for peptide synthesis or by cleaving the protein or the precursor protein of the present invention with a suitable peptidase. The process for peptide synthesis may be a solid-phase synthesis and/or a liquid-phase synthesis. Namely, the objective peptide can be produced by condensing a partial peptide or amino acid capable of constituting the protein with the residual part thereof and, when the product has a protective group, the protective group is removed whereupon a desire peptide can be manufactured.

When a dhfr gene is used as a selective marker, the resistant cells are selected from a culture with a sequentially increased MTX concentration to amplify the DNA coding for the protein of the present invention with dhfr gene in the cells whereby an animal cell strain exhibiting far higher expression can be obtained. The protein of the present invention or a salt thereof can be also manufactured by culturing the transformant under a condition where the DNA coding for the protein of the present invention can be expressed to express and accumulate the protein of the present invention. Culture of the transformants ( transfectants ) of Escherichia or Bacillus species can be carried out preferably in a liquid culture medium.

If necessary, drugs such as 3β-indolyl acrylic acid can be added to the medium to improve efficiency of the promoter. In the case of Escherichia species as a host, the culture is carried out usually at about 15 to 43°C for about 3 to 24 hours. When necessary, aeration and stirring may be applied.

The antibodies against the protein of the present invention may be manufactured by methods per se known to those of skill in the art or methods similar thereto, using the protein of the present invention as antigen. For example, monoclonal antibodies and/or polyclonal antibodies can be manufactured by the method as given below. Preparation of Monoclonal Antibody: (a) Preparation of Monoclonal Antibody-Producing Cells The protein of the present invention is administered to warm-blooded animals either solely or together with a carrier or a diluent to the site favorable for antibody production. In order to potentiate the antibody productivity upon the administration, complete Freund's adjuvant or incomplete Freund's adjuvant may be administered. The administration is usually carried out once every 2 to 6 weeks and 2 to 10 times in total. Examples of the applicable warm-blooded animals are monkeys, rabbits, dogs, guinea pigs, mice, rats, sheep, goats and fowls. The use of mice or rats is preferred. In establishing cells which produce monoclonal antibodies, an animal with the detectable antibody titer is selected from animals (e.g. mice) immunized with antigens, then spleen or lymph node is collected after 2 to 5 days from the final immunization and antibody-producing cells contained therein are fused with myeloma cells derived from homogeneous or heterogeneous animals to obtain monoclonal antibody- producing hybridomas . Measurement of the antibody titer in antisera may, for example, be carried out by reacting a labeled protein, which will be mentioned later, with the antiserum followed by measuring the binding activity of the labeling agent with the antibody. The cell fusion may be carried out, for example, by the method of Koehler and Milstein (Nature, 256, 495, 1975). Examples of the fusion accelerator are polyethylene glycol (PEG), Sendai virus, etc. and the use of PEG is preferred. Examples of the myeloma cells are those derived from warm-blooded animals such as NS-1, P3U1, SP2/0, AP-1, etc. and the use of P3U1 is preferred. The preferred fusion ratio of the numbers of antibody- producing cells used (spleen cells) to the numbers of myeloma cells is within a range of about 1:1 to 20:1. When PEG (preferably, PEG 1000 to PEG 6000) is added at a concentration of about 10 to 80% followed by incubating at 20 to 40°C, preferably, at 30 to 37°C, for 1 to 10 minutes, an efficient cell fusion can be carried out. Various methods may be applied for screening a hybridoma which produces a monoclonal antibody. For example, a supernatant of hybridoma culture is added to a solid phase (e.g. microplate) to which the protein antigen is adsorbed either directly or with a carrier, then anti-immunoglobulin antibody (anti-mouse immunoglobulin antibody is used when the cells used for the cell fusion are those of mouse) which is labeled with a radioactive substance, an enzyme or the like, or protein A is added thereto and then monoclonal antibodies bound on the solid phase are detected; or a supernatant of the hybridoma culture is added to the solid phase to which anti-immunoglobulin or protein A is adsorbed, and then the protein labeled with a radioactive substance or an enzyme is added and monoclonal antibodies bound with the solid phase is detected. Selection and cloning of the monoclonal antibody- producing hybridoma may be carried out by methods per se known to those of skill in the art or methods similar thereto. Usually, it is carried out in a medium for animal cells, containing HAT (hypoxanthine, aminopterin and thymidine) . With respect to a medium for the selection, for the cloning and for the growth, any medium may be used so far as hybridoma is able to grow therein. Examples of the medium are an RPMI 1640 medium (Dainippon Pharmaceutical Co., Ltd., Japan) containing 1 to 20% (preferably 10 to 20%) of fetal calf serum (FCS), GIT medium (Wako Pure Chemical, Japan) containing 1 to 20% of fetal calf serum and a suitable serum-free medium for hybridoma (SFM-101; Nissui Seiyaku, Japan) . The culture temperature is usually 20 to 40°C and, preferably, about 37°C. The culture period is usually from five days to three weeks and, preferably, one to two weeks. The culture is usually carried out in 5% carbon dioxide gas. The antibody titer of the supernatant of the hybridoma culture may be measured by the same manner as in the above-mentioned measurement of the antibody titer in the antiserum. (b) Purification of the Monoclonal Antibody The separation and purification of the monoclonal antibody may be carried out by methods for separating/purifying immunoglobulin such as salting- out, precipitation with alcohol, isoelectric precipitation, electrophoresis, adsorption/deadsorption using ion exchangers such as DEAE, ultracentrifugation, gel filtration, specific purifying methods in which only an antibody is collected by treatment with an active adsorbent such as an antigen-binding solid phase, protein A or protein G and the bond is dissociated whereupon the antibody is obtained. Preparation of Polyclonal Antibody: The polyclonal antibody of the present invention can be produced by per se known methods or methods analogous thereto. The method comprises preparing an immunogen (antigen protein) per se or a conjugate of an imunogen with a carrier protein, immunizing a warmblooded animal in the same manner as described for the production of the monoclonal antibody, harvesting a fraction containing the antibody against the protein of the present invention from the immunized animal, and purifying the harvested antibody. Referring to the immunogen-carrier protein conjugate for use in the immunization of a warm-blooded animal, the kind of carrier protein and the ratio of the carrier and hapten are not particularly restricted only if the production of the antibody against the hapten conjugated with the particular carrier protein and used for immunization proceeds efficiently. Thus, for example, bovine serum albumin, bovine thyroglobulin, hemocyanine, or the like is coupled in the weight ratio of about 0.1 to 20, preferably about 1 to about 5, to unity of the hapten. A variety of condensing agents can be used for this coupling between the hapten and the carrier. Thus, for example, a glutaraldehyde, carbodiimide, maleimide, or a thiol or dithiopyridyl group-containing active ester reagent can be employed. The condensation reaction product is administered to a warm-blooded animal at a site favorable for antibody production, either as it is alone or together with a carrier or diluent. Enhancing antibody production, complete Freund's adjuvant or incomplete Freund's adjuvant may be administered. Administration is carried out generally once in about 2 to 6 weeks for a total of about 3 to 10 times. The polyclonal antibody can be harvested from the blood, ascites fluid, or other body fluid, preferably from the blood, of the host warm-blooded animal. The polyclonal antibody titer in the antiserum can be determined in the same manner as the determination of monoclonal antibody described hereinbefore. The separation and purification of the polyclonal antibody can be carried out by the same method as that described for the separation and purification of monoclonal antibody.

(3) Quantitative determination of the protein of the present invention The antibody of the present invention is capable of specifically recognizing the protein, etc. of the present invention and, accordingly, it can be used for quantitative determination of the protein, etc. of the present invention in test liquid samples and particularly for quantitative determination by sandwich immunoassays . Thus, the present invention provides, for example, the following methods: (i) a quantitative determination of the protein, etc. of the present invention in a test liquid sample, which comprises (a) competitively reacting the test liquid sample and a labeled protein, etc. of the present invention with the antibody of the present invention, and (b) measuring the ratio of the labeled protein, etc. of the present invention binding with said antibody; and (ii) a quantitative determination of the protein, etc. of the present invention in a test liquid sample, which comprises (a) reacting the test liquid sample with an antibody immobilized on an insoluble carrier and a labeled antibody simultaneously or continuously, and (b) measuring the activity of the labeling agent on the insoluble carrier, wherein one antibody is capable of recognizing the N-terminal region of the protein, etc. of the present invention while another antibody is capable of recognizing the C-terminal region of the protein, etc. of the present invention. When the monoclonal antibody of the present invention recognizing a protein, etc. of the present invention (hereinafter, sometimes referred to as "monoclonal antibody of the present invention") is used, the quantity of the protein, etc. of the present invention can be measured and, moreover, the protein, etc. of the present invention can be detected by means of a tissue staining, etc. as well. For such an object, antibody molecules per se may be used, or F(ab') 2 Fab' or Fab fractions of the antibody molecule may also be used. There is no particular limitation for the measuring method using the antibody of the present invention and any measuring method may be used so far as it relates to a method in which the amount of antibody, antigen or antibody-antigen complex, depending on or corresponding to the amount of antigen, e.g. the amount of the protein, etc. of the present invention in the liquid sample to be measured, is detected by a chemical or a physical means and then calculated using a standard curve prepared by a standard solution containing the known amount of antigen. For exmaple, nephrometry, competitive method, immunometric method and sandwich method are suitably used and, in terms of sensitivity and specificity, the sandwich method which will be described herein later is particularly preferred. Examples of the labeling agent used in the measuring method using the labeling substance are radioisotopes , enzymes, fluorescent substances, luminescent substances, colloids, magnetic substances, etc.. Examples of the radioisotope are [ 125ϊ], [ 131I], [ 3H] and [ 14C]. Preferred examples of the enzyme are those which are stable and with much specific activity, such as β-galactosidase, β-glucosidase, alkaline phosphatase, peroxidase and malate dehydrogenase. Examples of the fluorescent substance are fluorescamine, fluorescein isothiocyanate, etc.. Examples of the luminescent substance are luminol, luminol derivatives, luciferin, lucigenin, etc.. Further, a biotin-avidin system may also be used for binding an antibody or antigen with a labeling agent. In insolubilization (immobilization) of antigens or antibodies, a physical adsorption may be used or a chemical binding which is usually used for insolubilization or immobilization of proteins or enzymes may be used as well . Examples of the carrier are insoluble polysaccharides such as agarose, dextran and cellulose; synthetic resins such as polystyrene, polyacrylamide and silicone; glass; etc.. In a sandwich method, the test liquid is allowed to react with an insolubilized monoclonal antibody of the present invention (the first reaction), then it is allowed to react with another labeled monoclonal antibody of the present invention (the second reaction) and the activity of the labeling agent on the insoluble carrier is measured whereupon the amount of the protein, etc. of the present invention in the test liquid can be determined. The first reaction and the second reaction may be conducted reversibly or simultaneously or they may be conducted with an interval . The type of the labeling agent and the method of insolubilization may be the same as those mentioned hereinbefore. In the immunoassay by means of a sandwich method, it is not always necessary that the antibody used for the labeled antibody and the antibody for the solid phase is one type or one species but, with an object of improving the measuring sensitivity, etc . , a combination of two or more antibodies may be used as well. In the method of measuring the protein, etc. of the present invention by the sandwich method of the present invention, the preferred monoclonal antibodies of the present invention used for the first and the second reactions are antibodies wherein their sites binding to the protein of the present invention are different from each other. Thus, antibodies used in the first and the second reactions are those wherein, when an antibody used in the second reaction recognizes the C-terminal region of the protein, etc. of the present invention, then another antibody recognizing the site other than C-terminal regions, e.g. recognizing the N-terminal region, is preferably used in the first reaction. The monoclonal antibody of the present invention may be used in a measuring system other than the sandwich method such as a competitive method, an immunometric method and a nephrometry. In the competitive method, an antigen in the test solution and a labeled antigen are allowed to react with an antibody in a competitive manner, then an unreacted labeled antigen (F) and a labeled antigen (B) binding with an antibody are separated (i.e. B/F separation) and the labeled amount of any of B and F is measured whereupon the amount of the antigen in the test solution is determined. With respect to the method for such a reaction, there are a liquid phase method in which a soluble antibody is used as the antibody and the B/F separation is conducted by polyethylene glycol, a second antibody to the above- mentioned antibody, etc.; and a solid phase method in which an immobilized antibody is used as the first antibody or a soluble antibody is used as the first antibody while an immobilized antibody is used as the second antibody. In the immunometric method, an antigen in the test solution and an immobilized antigen are subjected to a competitive reaction with a certain amount of a labeled antibody followed by separation into solid and liquid phases or the antigen in the test solution and an excess amount of labeled antibody are allowed to react, then an immobilized antigen is added to bind an unreacted labeled antibody with the solid phase and separated into solid and liquid phases. After that, the labeled amount of any of the phases is measured to determine the antigen amount in the test solution. In the nephrometry, the amount of insoluble sediment which is produced as a result of the antigen- antibody reaction in a gel or in a solution is " measured. Even when the antigen amount in the test solution is small and only a small amount of the sediment is obtained, a laser nephrometry wherein scattering of laser is utilized can be suitably used. In applying each of those immunological measuring methods (immunoassays) to the measuring method of the present invention, it is not necessary to set up any special condition, operation, etc. therefor. A measuring system (assay system) for the protein of the present invention may be constructed taking the technical consideration of the persons skilled in the art into consideration in the conventional conditions and operations for each of the methods. With details of those conventional technical means, a variety of reviews, reference books, etc. may be referred to.

Therefore, the DNA of the present invention is useful as a gene diagnostic agent for the damage to the DNA or mRNA, mutation thereof, or decreased expression thereof, or increased expression or over expression of the DNA or mRNA. For example, when the increase of the mRNA coding for the protein, etc. or the increase of the protein, etc. of the present invention is detected, it may be lead to the diagnosis of malnutrition, abetalipoproteinemia or Tangier disease, etc. On the other hand, the deficit or lack of the DNA or mRNA or the decrease of the protein, or a mutation of the DNA is detected by the PCR-SSCP assay etc. is detected, it may be lead to the diagnosis of arteriosclerosis, atherosclerosis, hyperlipidemia, hypercalorism, obesity, hypertriglyceridemia, inflammatory diseases, senescence, diseased of brain, renal disorder, etc. The above-mentioned gene diagnosis using the DNA of the present invention can be carried out by, for example, the per se known Northern hybridization assay or PCR-SSCP assay (Genomics, 5, 874-879 (1989); Proceedings of the National Academy of Sciences of the United States of America, 86, 2766-2770 (1989)). When increase in expression of the mRNA coding for the protein, etc. of the present invention is detected by Northern hybridization assay, it may lead, with high probability, to the diagnosis of malnutrition, abetalipoproteinemia or Tangier disease, etc. When decrease in expression of the mRNA or a mutation of the DNA is detected by the PCR-SSCP assay is detected it may lead, with high probability, to the diagnosis of arteriosclerosis, atherosclerosis, hyperlipidemia, hypercalorism, obesity, hypertriglyceridemia, etc. (5) Pharmaceutical composition containing the antisense DNA The antisense DNA which is capable of complementarily binding to the DNA coding for the protein, etc. of the present invention and suppresses the expression of the DNA and the protein, etc. of the present invention is capable of inhibiting the function of the protein, etc. or the DNA coding for the protein, etc. of the present invention which show the above- mentioned activities in vivo.

Preferable promoters are promoters conducive to high expression in the whole body, such as cytomegalovirus promoter, human polypeptide chain elongation factor 1 (EF-1 α) promoter, and human and chicken β-actin promoters . The vector preferably has a sequence for terminating the transcription of the objective mRNA (generally called terminator) in the transgenic mammal. The examples of the sequence are sequences derived from viruses, various mammals. Preferable examples are the SV40 terminator derived from simian virus, and so on. In addition, for enhanced the expression of the objective DNA, it is possible, depending on the specific objective, to link the splicing signal, enhancer domain, a portion of the eucaryotic DNA intron, etc. at upstream of the 5 ' -end of the promoter region, between the promoter region and the translated region, or at downstream of the 3 ' -end of the translated region. The translated region of the normal protein of the present invention can be obtained, as the whole or part of the genomic DNA, from the DNAs derived from the liver, kidney, or thyroid cells or fibroblasts of various mammals (e.g. rabbit, canine, feline, guinea pig, hamster, rat, murine, man, etc.) or from various commercial genomic DNA libraries, or starting with the complementary DNAs prepared from RNAs derived from the liver, kidney, thyroid cells or fibroblasts by the known technique. The foreign abnormal DNA can be constructed by mutating the translated region of the normal protein obtained from the above-mentioned cells or tissues by the mutagenesis method. The translated region can be prepared as a DNA construct which can be expressed in a transgenic animal, by the routine recombinant DNA technique, i.e. by coupling it at downstream of the promoter and, if desired, at upstream of the transcription termination site . The transfer of the DNA of the present invention at the fertilized egg cell stage insures that the DNA will be ubiquitous in all the germ cells and somatic cells of the host mammal. The presence of the DNA of the present invention in the germ cells of the transgenic animal following DNA transfer means that all the germ cells and somatic cells of all the progeny of the transgenic animal harbor the DNA of the present invention. Thus, the offspring of animals of this line to which DNA is passed down have the DNA of the present invention in their germ cells and somatic cells. The non-human mammal to which the foreign normal DNA of the present invention has been transferred can be verified by mating to retain the DNA stably and then bred as a strain harboring the transferred DNA from generation to generation under the usual breeding conditions. The transfer of the DNA of the present invention in the fertilized egg cell stage is carried out in such a manner that the transferred DNA will be present in excess in all the germ cells and somatic cells of the transgenic animal. The presence of an excess of the DNA of the present invention in the germ cells of the transgenic animal means that all the progeny of this line harbor an excess of the DNA of the present invention in their germ cells and somatic cells . By preparing homozygous animals having the transferred DNA in both homologous chromosomes and mating the animals of both sexes, they can be bred serially so that all the progeny may harbor an excess of the DNA. The non-human mammal harboring the normal DNA of the present invention features a high expression of the DNA and may eventually develop a hyperergasia of the protein of the present invention through activation of the function of the endogenous normal DNA and, therefore, can be utilized as an animal model of the disease. For example, by using the transgenic animal harboring the normal DNA of the present invention, it is possible to study the hyperergasia of the protein of the present invention to elucidate the mechanisms of diseases with which the protein of the present invention is associated, and explore therapeutic modalities for the diseases . Furthermore, the mammal to which the foreign normal DNA of the present invention has been transferred presents with symptoms due to an increase in the free protein of the present invention and, therefore, can also be used in the screening of therapeutic drugs for diseases with which the protein of the present invention is associated. On the other hand, the non-human mammal harboring the foreign abnormal DNA of the present invention can be verified by mating to retain the DNA stably and then bred as a line harboring the DNA from generation to generation under the usual breeding conditions . Moreover, it is possible to incorporate the objective DNA in the above-mentioned plasmid for use as a starting material . The DNA construct with the promoter can be prepared by the routine recombinant DNA technique. Transfer of the abnormal DNA of the present invention in the fertilized egg cell stage insures that the transferred DNA will be ubiquitous in all the germ cells and somatic cells of the host mammal. The presence of the abnormal DNA of the present invention in the germ cells of the transgenic animal means that all the offspring of this transgenic animal harbor the abnormal DNA of the present invention in all of their germ cells and somatic cells. The progeny of this animal harbor the abnormal DNA of the present invention in all of their germ cells and somatic cells. By preparing homozygous male and female animals having the introduced DNA in both homologous chromosomes and mating them, it can be insured that all their offsprings harbor the DNA. The non-human mammal harboring the abnormal DNA of the present invention features a high expression of the abnormal DNA and, therefore, may eventually develop adiaphoria associated with functional inactivation of the protein of the present invention through inhibition of the function of the endogenous normal DNA and, therefore, can be utilized as an animal model of the disease. For example, by using the transgenic animal harboring the abnormal DNA of the present invention, analysis of the mechanism of this functional inactivation adiaphoria due to the protein of the present invention and therapeutic modalities for the disease can be explored. As a specific potential use, the transgenic animal with a high expression of the abnormal DNA of the present invention can be used as a model for elucidating the functional inhibition of the normal protein by the abnormal protein of the present invention (dominant negative effect) in adiaphoria of functional inactivation type due to the protein of the present invention. Moreover, the transgenic mammal harboring the foreign abnormal DNA of the present invention develops symptoms due to an increase in the free protein of the present invention and, therefore, can be utilized in the screening of therapeutic compounds for functional inactivation of the protein of the present invention. As other potential uses for transgenic animals harboring the two kinds of DNAs described above, the following uses can be suggested. (1) Use as a cell source for tissue culture; (2) Analysis of the relationship of the protein of the present invention to proteins which are specifically expressed or activated by the protein by direct analysis of DNAs or RNAs in the tissues of the transgenic mammal harboring the DNA of the present invention or analysis of the composition of the protein expressed by the DNA; (3) Study of the functions of cells of those tissues which are generally difficult to culture by using the cells from the tissues containing the DNA as cultured by the standard tissue culture technique; (4) Screening of drugs capable of enhancing the cell functions by using the cells described in (3); (5) Isolation and purification of the muteins of the present invention and construction of antibodies to the muteins . Furthermore, by using the transgenic animal of the present invention, clinical symptoms of diseases associated with the protein of the present invention, inclusive of said functional inactivation of the protein of the present invention, can be investigated. In addition, more detailed pathological findings can be generated in various organs of this model of diseases associated with the protein of the present invention, thus contributing to the development of new therapies and the study and treatment of secondary diseases arising from such diseases. Moreover, following isolation of various organs from the transgenic animal of the present invention and their mincing and digestion with a proteolytic enzyme such as trypsin, free single cells harboring the transferred gene can be recovered and cultured for establishment of a cell line. Furthermore, characterization of cells producing the protein of the present invention can be made and their relationship to apotosis, differentiation, or proliferation, the mechanism of signal transduction in them, and abnormalities involved can be explored to thereby generate information useful for a further elucidation of the protein of the present invention and its actions . Moreover, for the development of therapeutic drugs for diseases associated with the protein of the present invention, such as functional inactivation of the protein of the present invention by using the transgenic animal of the present invention, an effective and rapid screening technology for such therapeutic drugs can be established by using the test and assay methods described hereinbefore. In addition, by using the above transgenic animal or the foreign DNA expression vector of the present invention, gene therapies for diseases associated with the protein of the present invention can be explored and developed. (8) Construction of knockout animals The present invention further provides a non-human mammalian embryonic stem cell wherein the DNA of the present invention is inactivated and a non-human mammal deficient in expression of the DNA of the present invention wherein the DNA is inactivated. The present invention, therefore, provides: (1) a non-human mammalian embryonic stem cell wherein the DNA of the present invention is inactivated; (2) the non-human mammalian embryonic stem cell according to in (1) wherein the DNA is inactivated by introduction of a reporter gene (e.g. a β-galactosidase gene of the E. coli origin); (3) the non-human mammalian embryonic stem cell according to (1) which is neomycin-resistant ; (4) the non-human mammalian embryonic stem cell according to (1) wherein the non-human mammal is a rodent; (5) the non-human mammalian embryonic stem cell according to (4) wherein the rodent is a mouse; (6) a non-human mammal deficient in expression of the DNA of the present invention, wherein the DNA is inactivated; (7) the non-human mammal according to (6) wherein the DNA is inactivated by introduction of a reporter gene (e.g. a β-galactosidase gene of E. coli origin) and the reporter gene can be expressed under the control of the promoter against the DNA of the present invention; (8) the non-human mammal according to (6) wherein the non-human mammal is a rodent; (9) the non-human mammal according to (8) wherein the rodent is a mouse; and (10) a method for screening for a compound or a salt thereof which enhances or inhibits an activity of the promoter against the DNA of the present invention, which comprises administering a test compound to the non-human mammal according to (7) and detecting an expression of the reporter gene. The term "non-human mammalian embryonic stem cell wherein the DNA of the present invention in inactivated" means the embryonic stem cell (hereinafter referred to briefly as ES cell) of a non-human mammal in which the DNA has been deprived of the capacity to express the protein of the present invention (hereinafter referred to sometimes as the knockout DNA of the present invention) through introduction of an artificial mutation to the DNA of the present invention possessed by the non-human mammal to thereby inhibit expression of the DNA of the present invention or through substantial deprivation of the activity of the protein of the present invention which is encoded by the DNA. The non-human mammal includes the same animals mentioned hereinbefore. Examples of the method for introducing an artificial mutation to the DNA of the present invention are a deletion of some or all of the DNA sequence, or an insertion or substitution of a different DNA by the genetic engineering technology. By such a mutation, the codon reading frame can be shifted or the function of the promoter or exon can be disrupted to provide the knockout DNA of the present invention. The non-human mammalian embryonic stem cell wherein the DNA of the present invention is inactivated (hereinafter referred to as the ES cell wherein the DNA is the inactivated of the present invention or the knockout ES cell of the present invention) can be prepared by, for example, a procedure which comprises isolating the DNA of the present invention from an objective non-human mammal, inserting a drug-resistance gene, typically the neomycin-resistance gene or hygromycin-resistance gene, or a reporter gene such as lacZ (β-galactosidase gene) or cat (chloramphenicol acetyltransferase gene) in its exon region to disrupt the function of the exon or inserting a DNA sequence for terminating gene transcription (e.g. poly A coupling signal) in the intron region between exons to thereby inhibit synthesis of a complete mRNA, introducing the thus-constructed DNA chain having a DNA sequence adapted to eventually disrupt the gene (hereinafter referred to briefly as the targeting vector) into the chromosomes of the host animal by homologous recombination, subjecting the resulting ES cell to Southern hybridization analysis using the DNA sequence on the DNA of the present invention or in its vicinity as the probe or a PCR procedure using the DNA sequence on the targeting vector and a DNA sequence in the vicinity but not including the DNA of the present invention used in the construction of the targeting vector as primers, and selecting the knockout ES cell of the present invention. Moreover, the original ES cell used for inactivation of the DNA of the present invention by the homologous recombination technique or the like may be an already established cell line such as those mentioned hereinbefore or a new cell line established de novo by the known method of Evans and Kaufma. Taking murine ES cells as an example, ES cells of the 129 line are generally employed but the immunological background of this line is not clear. Therefore, the cell line established by using BDFl mice created by the hybridization of C57BL/6 mice and C57BL/6 mice, both yielding few eggs, with DBA/2 mice (BDFl = FI of C57BL/6 and DBA/2) for preparing pure-line ES cells with an immunologically defined genetic background can be used with advantage. In addition to the advantage of high egg output and sturdiness of the egg, BDFl mice have the background of C57BL/6 mice so that in the construction of a disease model with ES cells obtained, the genetic background of the model mice can be converted to that of C57BL/6 mice by back-crossing with C57BL/6. Moreover, in establishing an ES cell line, it is common practice to use blastocytes 3.5 days following fertilization but, aside from them, a large number of early embryos can be prepared with high efficiency by harvesting the embryos at the 8-cell stage and culturing them into blastocytes . Furthermore, while ES cells from both male and female animals can be employed, generally ES cells of a male animal are more convenient for the construction of reproduction line chimeras. Moreover, for the purpose of reducing the burden of the complicated cultural procedure, it is preferable to carry out sexing as early as possible. As a typical method for sexing ES cells, there can be mentioned the method in which the gene in the sex determination region on the Y chromosome is amplified and detected by PCR. Whereas the conventional karyotype analysis requires about 10 cells, the above method requires only about one colony equivalent of ES cells (about 50 cells). Therefore, the primary selection of ES cells in an early stage can be made by this sexing method. Since male cells can thus be selected in the early stage, the trouble in the initial stage of culture can be drastically reduced. Moreover, the secondary selection can be carried out by G-banding for the number of chromosomes . The number of chromosomes in the resulting ES cell is preferably 100% of the normal number but this goal may not be reached due to the physical and other factors involved in the establishment of the line. In such cases, it is preferable to knockout the gene of the ES cell and redone it in the normal cell (taking a mouse as an example, the cell in which the number of chromosomes is 2n=40). The embryonic stem cell line thus established is generally very satisfactory in proliferation characteristic but since it is liable to lose its ontogenic ability, it must be subcultured with sufficient care. For example, this cell line should be cultured on suitable feeder cells such as STO fibroblasts in the presence of LIF (1-10000 U/ml) in a carbon dioxide incubator (preferably 5% C0 2 -95% air or 5% oxygen-5% CO 2 -90% air) at about 37°C and, in subculture, it should be treated with trypsin/EDTA solution (generally 0.001-0.5% trypsin/0.1-5 mM EDTA, preferably about 0.1% trypsin/1 mM EDTA) to provide single cells and seed them on freshly prepared feeder cells. While such subculture is generally performed every 1-3 days, it is good practice to observe the cells on each occasion and, whenever morphologically abnormal cells are discovered, discard the culture. ES cells can be allowed to differentiate into various types of cells, such as head long muscle cells, visceral muscle cells, heart muscle cells, etc. by conducting monolayer culture to a high density under suitable conditions or suspension culture until a mass of cells is formed (M. J. Evans & M. H. Kaufman, Nature, 292, 154, 1981; G. R. Martin, Proceedings of National Academy of Science USA, 78, 7634, 1981; T. C. Doetschman et al., Journal of Embryology and Experimental Morphology, 87, 27, 1985), and the cell deficient in expression of the DNA of the present invention as obtained by causing the ES cell of the present invention to differentiate is useful for the cytobiological in vitro study of the protein of the present invention. The non-human mammal deficient in expression of the DNA of the present invention can be differentiated from the normal animal by assaying the mRNA in the animals by the known method and comparing the amounts of expression indirectly. The non-human mammal used for this purpose includes the animals mentioned hereinbefore. Referring to the non-human mammal deficient in expression of the DNA of the present invention, the DNA of the present invention can be knocked out by introducing the targeting vector constructed as above into, for example, a murine embryonic stem cell or a " murine egg cell and thereby causing the DNA sequence of the targeting vector harboring the inactivated DNA of the present invention to undergo homologous recombination with, and accordingly replacing, the DNA of the present invention on the murine embryonic stem cell or egg cell chromosomes. The cell with the DNA of the present invention thus knocked out can be obtained by Southern hybridization analysis using a DNA sequence on the DNA of the present invention or in its vicinity as a probe or by PCR using a DNA sequence on the targeting vector or a murine-derived DNA sequence in a region adjacent to but not including the DNA of the present invention used in the targeting vector as primers . When a nonhuman mammalian embryonic stem cell is used, a cell line with the DNA of the present invention knocked out by the homologous recombination technique is cloned and injected into the non-human mammalian embryo or blastocyte at a suitable stage of embryogenesis, for example at the 8-cell stage, and the resulting chimera embryo is transplanted in the pseudopregnant uterus of the non-human mammal . The animal thus obtained is a chimera animal constituted by both the cells harboring the normal DNA of the present invention and the cells harboring the artificially mutated DNA of the present invention. When some of the gametes of this chimera animal harbor the mutated DNA of the present invention, an individual of which the entire tissues are constituted by cells harboring the mutated DNA of the present invention can be screened from the colony of animals obtained by crossing such a chimera animal with a normal animal, for example by coat color discrimination. The individuals thus selected are usually animals deficient in hetero-expression of the protein of the present invention and by mating such individuals deficient in hetero-expression of the protein of the present invention with each other, animals deficient in homo-expression of the protein of the present invention can be acquired. When an egg cell is used, a transgenic non-human mammal with the targeting vector having been introduced into its chromosomes can be prepared by injecting the DNA solution into the egg cell nucleus by the microinjection technique and selecting animals expressing a mutation of the DNA of the present invention by homologous recombination. The individuals with the DNA of the present invention knocked out are mated to verify that the animals obtained by mating also have the DNA knocked out and they can be sub-bred under the usual breeding conditions. Preparation and maintenance of the reproduction line can also be carried out in the routine manner. Thus, by mating male and female animals harboring the inactivated DNA, homozygotes having the inactivated DNA in both homologous chromosomes can be obtained. The homozygotes thus obtained are bred under such conditions that, with regard to the dam, the number of homozygotes is plural per normal individual. By mating male and female heterozygotes, homozygotes and heterozygotes both harboring the inactivated DNA can be sub-bread. The non-human mammalian embryonic stem cell harboring the inactivated DNA of the present invention is very useful for the construction of non-human mammals deficient in expression of the DNA of the present invention. Moreover, the mouse deficient in expression of the protein of the present invention lacks the various biological activities inducible by the protein of the present invention and can, therefore, be of use as an animal model of diseases arising from inactivation of the biological activities of the protein of the present invention, thus being of use in the etiological studies of diseases and development of therapeutics. (8a) A method for screening for a compound having an effect for treating or preventing in the various diseases caused by a defect in or damage to the DNA of the present invention A non-human mammal deficient in expression of the DNA of the present invention can be used in the screening for a compound having an effect for treating or preventing in the diseases (e.g. arteriosclerosis, atherosclerosis, hyperlipidemia, hypercalorism, obesity, hypertriglyceridemia, inflammatory diseases, senescence, diseases of brain, renal disorder, etc.) caused by a defect in or damage to the DNA of the present invention. Thus, the present invention provides a method for screening for a compound, or a salt thereof, which has an effect for treating or preventing in the diseases caused by a defect in or damage to the DNA of the present invention, which method comprises administering a test compound to a non-human mammal deficient in expression of the DNA of the present invention and monitoring or measuring a change of the non-human mammal . The non-human mammal deficient in expression of the DNA of the present invention, which is to be used in this screening method, includes the same animals as those mentioned above. The test compound includes peptides, proteins, non-peptide compounds, synthetic compounds, fermentation products, cell extracts, plant extracts, animal tissue extracts, blood plasma and so on. The test compound may be novel or known compounds . More specifically, the non-human mammal deficient in expression of the DNA of the present invention is treated with the test compound and the treated animal is compared with an untreated control to evaluate the test compound for an effect for treating or preventing the diseases mentioned above by using a change in some organ or tissue or in a disease symptom as an indicator. The method of treating the test animal with a test compound can be selected according to the symptom or symptoms manifested by the test animal and the characteristics of the test compound, among other factors and, for example, oral administration or intravenous injection can be employed. The dosage of the test compound can be suitably selected according to the route of administration, the properties of the test compound, and other conditions. In the screening for a compound with an effect for treating or preventing arteriosclerosis, atherosclerosis, hyperlipidemia, hypercalorism, obesity, hypertriglyceridemia, etc., for instance, the test compound is administered to the non-human mammals deficient in expression of the DNA of the present invention. And, changes in, blood glucose or body weight, etc. in the animal are determined at timed intervals . When, in the screening method, blood glucose in the test animal is increased about 10% or more, preferably about 30% or more, more preferably about 50% or more, following administration of the test compound, the particular test compound can be selected as a compound capable of producing an effect for treating or preventing arteriosclerosis, atherosclerosis. The compound obtained by the above screening method has an effect for treating or preventing the diseases (e.g. arteriosclerosis, atherosclerosis) caused by a defect in or damage to the protein, etc. of the present invention and, therefore, can be used as a drug, for example as a safe, low-toxicity agent for treating or preventing the diseases. Furthermore, compounds derived from the compound obtained by the above screening may also be used in the same manner. The salts of the compound obtained by the screening method as mentioned above include salts with physiologically acceptable bases (e.g. alkali metals) or acids such as organic or inorganic acids, and are preferably a physiologically acceptable acid addition salt. Examples of such salts are salts thereof with inorganic acids (e.g. hydrochloric acid, phisphoric acid, hydrobromic acid or sulfuric acid, etc.) and salts thereof with organic acids (e.g. acetic acid, formic acid, propionic acid, fumaric acid, aleic acid, succinic acid, tartaric acid, citric acid, malic acid, oxalic acid, benzoic acid, methanesulfonic acid or benzenesulfonic acid, etc.). The composition for treating or preventing the diseases mentioned above comprising the compound obtained the screening method can be prepared in the same as the pharmaceutical composition comprising the protein, etc. of the present invention as mentioned above . Because the thus-obtained preparation is safe and of low toxicity, it can be administered to humans or mammals (e.g., rat, mouse, guinia pig, rabbit, sheep, pig, bovine, horse, cat, dog, monkey, etc.). The dose of the compound may vary depending on subject disease, subject of administration, way of administration, and so on. When the compound is used, for example, for treating cancer by oral administration, the dose of the compound is normally about 0.1 to 100 mg, preferably 1.0 to 50 mg, and more preferably 1.0 to 20 mg per day for an adult human (weighing 60 kg) . When the compound is used, for example, for treating arteriosclerosis, atherosclerosis by non-oral administration, it is advantageous to administer the compound in the form of injectable preparation at a daily dose of about 0.01 to 30 mg, preferably about 0.1 to 20 mg, and more preferably about 0.1 to 10 mg per administration by an intravenous injection for an adult human (weighing 60 kg), depending on subject of administration, subject disease and so on. For other animal species, corresponding does as converted per 60 kg weight can be administered. (8b) A method for screening for a compound capable of promoting or inhibiting an activity of the promoter for the DNA of the present invention The present invention provides a method for screening for a compound, or a salt thereof, which promotes or inhibits an activity of the promoter for the DNA of the present invention, which method comprises administering a test compound to a non-human mammal deficient in expression of the DNA of the present invention, wherein the DNA of the present invention is inactivated by introducing of a reporter gene and detecting the expression of the reporter gene. As the test compound, the same compounds as those mentioned hereinbefore can be used. Examples of the reporter gene are the same genes as those mentioned hereinbefore. Preferable examples are a β-galactosidase gene (lacZ) and so on. In non-human mammals deficient in expression of the DNA of the present invention wherein the DNA of the present invention is inactivated by introducing a reporter gene, the reporter gene is under the control of the promoter for the DNA of the present invention and, therefore, the activity of the promoter can be detected by tracing the expression of the substance encoded by the reporter gene . For instance, when part of the DNA region coding for the protein of the present invention is inactivated by the Escherichia coli-derived β- galactosidase gene (lacZ), β-galactosidase is expressed in those tissues in which the protein of the present invention would have been expressed. Therefore, the status of expression of the protein of the present invention in a living animal body can be traced, easily and expediently, for example, by the staining method using a reagent serving as a substrate for β-galactosidase, such as 5-bromo-4-chloro-3-indolyl-β-galactopyranoside (X-gal). More specifically, a tissue section of a mouse defective in the protein of the present invention is fixed with glutaraldehyde or the like, washed with Dulbecco's phosphate-buffered saline (PBS), and reacted with a staining solution containing X-gal at room temperature or around 37 °C for about 30 minutes to 1 hour. The tissue sample is then washed with 1 mM EDTA/PBS solution to terminate the β-galactosidase reaction and observed for color development. Alternatively, the mRNA coding for lacZ may be detected by a conventional method. The compound, or a salt thereof, as obtained by the above screening method is a compound selected from among the test compounds mentioned above and, as such, is a compound capable of promoting or inhibiting the activity of the promoter for the DNA of the present invention. The salts of the compound obtained by the screening method as mentioned above include salts with physiologically acceptable bases (e.g. alkali metals) or acids such as organic or inorganic acids, and are preferably a physiologically acceptable acid addition salt. Examples of such salts are salts thereof with inorganic acids (e.g. hydrochloric acid, phisphoric acid, hydrobromic acid or sulfuric acid, etc.) and salts thereof with organic acids (e.g. acetic acid, formic acid, propionic acid, fumaric acid, maleic acid, succinic acid, tartaric acid, citric acid, malic acid, oxalic acid, benzoic acid, methanesulfonic acid or benzenesulfonic acid, etc.). The compound, or a salt thereof, which promotes the activity of the promoter for the DNA of the present invention is capable of promoting the expression of the protein of the present invention and, hence, the promoting function of the protein. Therefore, the compound is useful as a drug, such as a safe, low-toxic agent for treating or preventing diseases such as arteriosclerosis, atherosclerosis, hyperlipidemia, hypercalorism, obesity, hypertriglyceridemia, inflammatory diseases, senescence, diseases of brain, renal disorder, etc. On the other hand, the compound, or a salt thereof, which inhibits the activity of the promoter for the DNA of the present invention is capable of inhibiting expression of the protein of the present invention and, hence, inhibiting the function of the protein. Therefore, the compound is useful as a drug, such as a safe, low-toxic agent for treating or preventing diseases such as malnutrition, abetalipoproteinemia or Tangier disease, etc. Furthermore, compounds derived from the compound obtained by the above screening method may also be used in the same way. The agent for treating or preventing the above- mentioned diseases comprising the compound obtained the screening method can be prepared in the same as the pharmaceutical composition comprising the protein, etc. of the present invention as mentioned above. Because the thus-obtained preparation is safe and of low toxicity, it can be administered to humans or mammals (e.g., rat, mouse, guinia pig, rabbit, sheep, pig, bovine, horse, cat, dog, monkey, etc.). The dose of the compound may vary depending on subject disease, subject of administration, way of administration, and so on. When the compound which promotes an activity of the promoter is used, for example, for treating arteriosclerosis, atherosclerosis by oral administration, the dose of the compound which promotes an activity of the promoter is normally about 0.1 to 100 mg, preferably 1.0 to 50 mg, and more preferably 1.0 to 20 mg per day for an adult human (weighing 60 kg) . When the compound which promotes an activity of the promoter is used, for example, for treating arteriosclerosis, atherosclerosis by non-oral administration, it is advantageous to administer the compound which promotes an activity of the promoter in the form of injectable preparation at a daily dose of about 0.01 to 30 mg, preferably about 0.1 to 20 mg, and more preferably about 0.1 to 10 mg per administration by an intravenous injection for an adult human (weighing 60 kg), depending on subject of administration, subject disease and so on. For other animal species, corresponding dose as converted per 60 kg weight can be administered. When the compound which inhibits an activity of the promoter is used, for example, for treating abetalipoproteinemia by oral administration, the dose of the compound which inhibits an activity of the promoter is normally about 0.1 to 100 mg, preferably 1.0 to 50 mg, and more preferably 1.0 to 20 mg per day for an adult human (weighing 60 kg) . When the compound which inhibits an activity of the promoter is used, for example, for treating abetalipoproteinemia by non-oral administration, it is advantageous to administer the compound which inhibits an activity of the promoter in the form of injectable preparation at a daily dose of about 0.01 to 30 mg, preferably about 0.1 to 20 mg, and more preferably about 0.1 to 10 mg per administration by an intravenous injection for an adult human (weighing 60 kg) , depending on subject of administration, subject disease and so on. For other animal species, corresponding does as converted per 60 kg weight can be administered. In this way, the non-human mammal deficient in expression of the DNA of the present invention is very useful in view of the screening of a compound or a salt thereof which promotes or inhibits promoter activities of the DNA of the present invention, and useful for developing a pharmaceutical composition for treating or preventing various diseases arisen from deficiency in expression of the DNA of the present invention, and for analysis the in vivo mechanism of the various diseases. Also, various kinds of DNAs coding proteins can be linked at downstream of the DNA comprising a promoter region of the LCAT-like protein of the present invention (e.g. the DNA comprising a nucleotide sequence represented by SEQ ID NO: 38, substantially equivalent thereof, or a partial DNA thereof), to prepare a gene construct which can be microinjected into the fertilized egg of animals to produce transgenic animals. By using such transgenic animals, the mechanism of the protein in animals can be determined. Moreover, by linking a suitable receptor gene at the above-mentioned promoter, and by constructing a cell-line which can produce the protein of the present invention, it can be used as an assay system to find low-molecular compounds which specifically promote or inhibit a producing activity of the LCAT-like protein in vivo.

Best Mode for Carrying Out the present invention Examples The following examples are intended to describe the present invention in further detail and should by no means be interpreted as defining the scope of the present invention. The gene manipulation using Escherichia coli was carried out in accordance with the procedure described in Molecular Cloning. Example 1 Cloning of the gene coding for the human LCAT-like protein of the invention (1) Subtractive concentration of mRNA differing in the amount of expression between the foam cells prepared from the THP-1 cells made macrophage-like by two methods The preparation of foam cells from THP-1 cells (Dainippon Pharmaceutical) was carried out principally according to the method of A. Rodriguez et al . (Journal of Lipid Research, 35 . , 1909, 1994). Thus, THP-1 cells were made macrophage-like by 3-day treatment with 400 ng/ml of phorbol myristate acetate (PMA) and then exposed to 0.2 mg TC (total cholesterol ) /ml of β VLDL (very low density lipoprotein) for 1 day. The resultant cholesterol-loaded cells were used as a 400 ng PMA-treated THP-1-derived foam cell sample. Similarly, the same monocytes as used above were treated with 5 ng/ml of PMA for 5 days and the resultant macrophage-like cells were exposed to 0.2 mg TC/ml of β VLDL for one day to prepare a 5 ng PMA- treated THP-1-derived foam cell sample. From both samples, the total RNA was extracted with guanidine isothiocyanate (Pharmacia) and the poly(A)+RNA was purified by means of an oligo-dT cellulose column (Pharmacia). Starting with 2 μg of each poly(A)+RNA, a subtractive PCR was carried out using PCR-Select cDNA Subtraction Kit (Clontech) to collect a cDNA fragment (a PCR amplification product of a portion of the cDNA) specifically expressed in the 5 ng PMA-treated foam cell sample. The adapter sequences added for subtraction were cleaved off from both ends of the PCR product fragment by using the restriction enzyme Rsal and the blunt- ended DNA fragment thus obtained was subcloned in pCR- Script (Stratagene). The nucleotide sequences of the subcloned cDNA fragments were determined, and based on the sequences thus found, a homology search was made using the BLAST N program against Genemble Database, a public database. As a result, Clone 4S-086 (SEQ ID NO: 23) was found to have a novel DNA nucleotide sequence having approximately 61% similarity with the known human LCAT (Biochimica et Biophysica Acta, 910 , 142-148, 1987). (2) Isolation of the full-length cDNA based on clone 4S-086 cDNA fragment Using the above Clone 4S-086 as a probe, Northern analysis was performed with a commercial MTN membrane (Clontech) . This analysis revealed that the particular gene had been expressed mainly in the heart, placenta, skeletal muscle, kidney, and testis. Therefore, it was decided to isolate this full-length cDNA from human heart and human kidney cDNA libraries . Cloning of the cDNA was performed using Gene Trapper Positive Selection System (Gibco BRL). Escherichia coli DH12S strains from the human heart and human kidney cDNA libraries (Gibco BRL) were respectively cultured in Terrific Broth (12 g/1 bacto- tryptone (Difco), 24 g/1 bacto-yeast extract (Difco), 2.3 g/1 monopotassium phosphate, 12.5 g/1 dipotassium phosphate) at 30°C for 16 hours, and using Quiagen Plasmid Isolation Kit (Quiagen), plasmid cDNA libraries were extracted and purified. The purified plasmid cDNA libraries were respectively digested with Genell and ExoIII (both from Gibco BRL) to construct single- stranded cDNA libraries. The following synthetic oligonucleotide was used as a probe in the screening of cDNA libraries. 5'-GCTGCTGCCCTACAACTACACAT-3' (SEQ ID NO: 24) The 3' end of the probe was labeled with TdT tailed with biotin-14-dCTP (Gibco BRL) . Each single-stranded cDNA library was incubated at 95°C for 1 minute and quenched on ice. Then, the biotinylated probe was added and 1-hour prehybridization at 37 °C and hybridization at room temperature were carried out. After hybridization, Gene Trapper Positive Selection System Magnetic Beads (Gibco BRL) were added and the system was incubated for 30 minutes at room temperature with stirring at 2-minute intervals. Then, the system was placed in Gene Trapper Positive Selection System Magnet Track (Gibco BRL) and allowed to stand for 2 minutes . The supernatant was discarded and the Magnetic Beads were washed with Gene Trapper Positive Selection System Wash Buffer. This washing with Wash Buffer was carried out 3 times. After standing in Magnetic Track, the supernatant was discarded. Then, Gene Trapper Positive Selection System Elution Buffer was added and the system was allowed to stand at room temperature for 5 minutes. After 5 minutes' standing in the Magnetic Track, the supernatant DNA solution was harvested . As a primer, the synthetic oligonucleotide: 5'-GCTGCTGCCCTACAACTACACAT-3' (SEQ ID NO: 24) was added to the harvested DNA solution and the mixture was incubated at 95°C for 1 minute. Then, Gene Trapper Positive Selection System Repair Enzyme was added and the system was incubated at 70°C for 15 minutes to synthesize a double-stranded DNA. Using an electropolator (Bio-Rad), the double-stranded DNA synthesized above was used to transform Escherichia coli DH10B. A screening for the positive transformants by colony-PCR using the following two oligonucleotides as primers was carried out. 5'-TATCCGGGCCTTCGTGTCA-3' (SEQ ID NO: 25) 5'-TCAAAGCCGATGTCCTGGAAGAACTTGC-3' (SEQ ID NO: 26) By detecting the colonies showing a PCR product of about 220 bp as positive clones, 2 clones each, or a total of 4 clones, were selected from the human heart and human kidney cDNA libraries. The selected E__ coli cells were respectively cultured and the DNA was extracted and subjected to a cycling reaction using ABI PRISH Dye Terminator Cycle Sequence Ready Reaction Kit with AmpliTaq DNA polymerase, FS (Perkin-Elmer ) and the nucleotide sequence of each cDNA fragment was determined using 377 DNA Sequencer (Perkin-Elmer). Then, based on the nucleotide sequences so determined, an alignment search was made. As a result, the two clones derived from the human heart cDNA library and one of the two clones derived from the human kidney cDNA library were found to harbor a 1271-base nucleotide sequence containing the sequence of SEQ ID NO: 17. The remaining one clone derived from the human kidney cDNA library harbored a 1335-base nucleotide sequence containing the sequence of SEQ ID NO: 18, which corresponded to the insertion of 96 bases into the sequence harbored by the above- mentioned 2 clones from the human heart cDNA library. In the former cDNA fragment, 412 amino acids of SEQ ID NO: 6 and, in the latter cDNA fragment, 444 amino acids of SEQ ID NO: 7 were respectively encoded, and both had novel LCAT-like proteins encoded. The plasmids pTB1972 and pTB1973 harboring the DNAs coding for the two novel LCAT-like proteins of the invention were respectively used to transform Escherichia coli DH10B to obtain two transformants, E ■ coli DH10B/pTB1972 and DH10B/pTB1973. Example 2 Cloning of the cDNA coding for a novel murine LCAT-like protein Cloning of a partial sequence of the novel murine LCAT-like protein was performed by PCR. Escherichia coli DH12S from a murine kidney cDNA library (Gibco BRL) was cultured in Terrific Broth (12 g/1 bacto- tryptone (Difco), 24 g/1 bacto-yeast extract (Difco), 2.3 g/1 monopotassium phosphate, 12.5 g/1 dipotassium phosphate) at 30°C for 16 hours, and using Quiagen Plasmid Kit (Quiagen), a plasmid cDNA library was constructed and used as a template. Based on the sequence data on the novel human LCAT-like proteins, the following two synthetic oligonucleotides were synthesized and used as primers. 5'-GTGGTGCTGGTCCCTGGTGATTTG-3' (SEQ ID NO: 27) 5'-GGTGGCCCTGGATGTTTTGTTG-3' (SEQ ID NO: 28) Using a thermal cycler (GeneA p PCR System 2400, Perkin-Elmer) , PCR reaction was carried out in a system containing TaKaRa Ex Taq (Takara Shuzo) in 30 cycles of 30 seconds at 94°C, 30 seconds at 55°C, one minute at 72°C, and extension at 4°C. The resultant PCR product was inserted into pT7 Blue-T-Vector (Novagen) using DNA Ligation Kit Version 2 (Takara Shuzo) and subcloned into Escherichia coli DH5α. From the transformant thus obtained, the plasmid DNA was extracted and subjected to a cyclizing reaction with Dye Terminator Cycle Sequence FS Ready Reaction Kit (Perkin-Elmer), and the nucleotide sequence of the cDNA fragment was determined with 377 DNA Sequencer (Perkin-Elmer). The harvested clone had a 198-base nucleotide sequence of SEQ ID NO: 29. Therefore, it was decided to obtain this full-length cDNA from the murine kidney cDNA library. Cloning of the cDNA was performed using Gene Trapper Positive Selection System (Gibco BRL). The plasmid cDNA library used above was digested with Genell and ExoIII (both from Gibco) to construct a single-stranded cDNA library. On the other hand, the following synthetic oligonucleotide was used as a probe in the screening of the cDNA library. 5 ' -GGTTGTACACTACCTTTGCTCCAAG-3' (SEQ ID NO:30) The 3 ' end of the probe was labeled by biotinylation using TdT/biotin-14-dCTP (Gibco BRL). The single-stranded cDNA library was denatured at 95°C for 1 minute and quenched on ice and the biotinylated probe was added. Prehybridization was performed at 37 °C for 1 hour, followed by hybridization at room temperature. After hybridization, Gene Trapper Positive Selection System Magnetic Beads were added and the system was allowed to stand for 30 minutes at room temperature with stirring at 2-minute intervals. Then, the system was put in Gene Trapper Positive Selection System Magnetic Track (Gibco BRL) and allowed to stand for 2 minutes . The supernatant was discarded and the Magnetic Beads were washed with Gene Trapper Positive Selection System Wash Buffer. This washing with Wash Buffer was carried out 3 times. After standing in the Magnetic Track, the supernatant was discarded. Then, Gene Trapper Positive Selection System Elution Buffer was added and the system was allowed to stand at room temperature for 5 minutes. After 5 minutes' standing in the Magnetic Track, the supernatant DNA solution was recovered. As a primer, the synthetic oligonucleotide: 5 '-GGTTGTACACTACCTTTGCTCCAAG-3' (SEQ ID NO: 30) was added to the above DNA solution and the mixture was incubated at 95°C for 1 minute. Then, Gene Trapper Positive Selection System Repair Enzyme was added and the system was incubated at 70 °C for 15 minutes to synthesize a double-stranded DNA. Using an electropolator (Bio-Rad), the double-stranded DNA synthesized above was used to transform Escherichia coli DH10B. A screening for the positive transformants by colony-PCR using the following two oligonucleotides as primers was carried out. 5'-GGTAACCAGTTGGAAGCAAAG-3' (SEQ ID NO: 31) 5 ' -ATCCAGCAGTCAATGATAACA-3 ' (SEQ ID NO : 32 ) By detecting the colonies showing a PCR product fragment of about 130 bp as positive clones, a total of 3 clones were selected from the murine kidney cDNA library. The selected E__ coli cells were respectively cultured and the DNA were respectively extracted and subjected to a cycling reaction using ABI PRISH Dye Terminator Cycle Sequence Ready Reaction Kit with AmpliTaq DNA polymerase, FS (Perkin-Elmer) and the nucleotide sequence of each cDNA fragment was determined using 377 DNA Sequencer (Perkin-Elmer). Then, based on the nucleotide sequences so determined, an alignment search was made. As a result, the three clones obtained were found to harbor the same DNA fragment and had a 2734-base nucleotide sequence containing the sequence of SEQ ID NO: 19. This cDNA fragment had 412 amino acids of SEQ ID NO: 8 encoded, and a novel murine LCAT-like protein was encoded. This novel murine LCAT-like protein had 85.0% similarity at the base level and 88.1% similarity at the amino acid level with the novel human LCAT-like protein having the amino acid sequence of SEQ ID NO:l as obtained in Example 1 [Fig. 4]. The plasmid pTB2010 harboring the DNA coding for the novel murine LCAT-like protein of the invention was used to transform Escherichia coli DH10B to provide a transformant, Escherichia coli DH10B/pTB2010. Example 3 Cloning of the genomic DNA of the novel human LCAT-like protein Using Promoter Finder DNA Working Kit (Clontech) , the sequence around the initiation codon of the DNA coding for the human protein of the invention was analyzed. The human genomic DNA was digested with Ssp I restriction enzyme and an adapter sequence [5'- GTAATACGACTCACTATAGGGCACGCGTGGTCGACGGCCCGGGCTGGT-3 ' (SEQ ID NO: 35)] available with Primer AP 1 [5'- GTAATACGACTCACTATAGGGC-3' (SEQ ID NO:33) (Clontech)] and Primer AP 2 [ 5 ' -ACTATAGGGCACGCGTGGT-3 ' (SEQ ID NO: 34) (Clontech)] was ligated to its 5' and 3' ends. The oligonucleotides GSP 1 [5'- ATCCGGGAGCAGCCCCACACGGTAGG-3' (SEQ ID NO: 36)] and GSP 2 [5'-GGTGTACGACGGTCGCCGCAGGTC-3' (SEQ ID NO:37)], which sequences are complementary to those from base +45 to base +20 and from base -1 to base -24 of the 5' flanking sequence (Fig. 5) of the cDNA coding for the novel human LCAT-like protein, respectively, were synthesized as PCR primers. The primary PCR was performed using the above human genomic DNA solution, TaKaRa LA PCR Kit Version 2 (Takara Shuzo), AP 1, and synthetic oligonucleotide GSP 1 on a thermal cycler (GeneAmpR PCR System 2400, Perkin-Elmer) in 30 cycles of 10 seconds at 95°C, 30 seconds at 65°C, and 5 minutes at 72°C. This reaction mixture was diluted 50-fold with sterilized water and subjected to the secondary PCR. The secondary PCR was carried out using the above primary PCR product dilution, TaKaRa LA PCR Kit Version 2 (Takara Shuzo), AP 2, and synthetic nucleotide GSP 2 on a thermal cycler (GeneAmpR PCR System 2400, Perkin-Elmer) in 25 cycles of 10 seconds at 95°C, 30 seconds at 65°C, and 5 minutes at 72°C. The about 2.9 kbp amplified fragment obtained from the Ssp I-digested genomic DNA solution was inserted into pT7 Blue-T-Vector (Novagen) using DNA Ligation Kit Version 2 (Takara Shuzo) and introduced into Escherichia coli DH5α to construct a transformant. From this transformant, the plasmid DNA was extracted and subjected to a cycling reaction using Dye Terminator Cycle Sequence FS Ready Reaction Kit (Perkin-Elmer) and the nucleotide sequence of the amplified product was determined with 377 DNA Sequencer (Perkin-Elmer). The sequence is shown in Figs. 6 and 7 . The clone thus obtained showed the existence of a sequence in complete agreement with the base -81 to base -25 of the 5' flanking sequence of the cDNA of the novel human LCAT-like protein in the base 2788 - base 2843 region of the sequence shown in Figs. 6 and 7, indicating that this sequence is the sequence of the 5' flanking region of the novel human LCAT-like protein gene. Analysis for the cis element in this flanking sequence was made using GENETYX Bio Database Software Ver . 32.0 (Software Development) and by inventor's eyes . Example 4 Assay of the promoter activity of the novel human LCAT- like protein gene To confirm that the genomic DNA fragment cloned in Example 3 has promoter activity, the promotor activity detection system was constructed using alkaline phosphatase gene as a reporter. The method for construction of a plasmid with alkaline phosphatase gene as the reporter gene under the control of the genomic DNA fragment obtained in Example 3 is illustrated in Fig. 8. First, from the plasmid with a sequence of about 2.9 kbp from the base 1 to base 2867 of the nucleotide sequence shown in Figs. 6 and 7 as cloned in pT7 Blue- T-Vector, the 2.9 kbp fragment was isolated using Mlu I-Hind III and introduced into the flanking Mlu I-Hind III site of the pSEAP-Basic (Clontech) alkaline phosphatase gene. This gene was then introduced into Escherichia coli DH5α to construct an expression plasmid pTB-2022. At the same time, the 2.9 kbp fragment was isolated with Hind III-EcoR I and inserted in the flanking Hind III-EcoR I site of the pSEAP-Basic alkaline phosphatase gene to construct a reverse- inserted expression plasmid as well. This plasmid was used as a negative control . Introduction of the plasmid into the WI38 VA13 cell line was carried out by the lipofectin method using Trans IT TM-LT1 (Mirus). Thus, the cells seeded at a density of 1x10 cells/962 mm 2 (a 6-well plate) were cultured for 24 hours. After serum-free medium was substituted, 3 μg/well of each plasmid and 10 μl/μg DNA of Trans IT-LTI were added and the plate was incubated for 4 hours. After transfection, the cells were cultured in DMEM medium containing 10% FBS (fetal bovine serium) and the supernatant was pooled after 72 hours. Using this cell supernatant, alkaline phosphatase activity was determined. The assay of alkaline phosphatase activity was performed (n=3) using Great EscAPeTMSEAP Reporter System 2 (Clontech) in accordance with the manual. Thus, 10 μl of the cell supernatant obtained by 10 minutes' centrifuging at 12000 x g was diluted 20-fold with 1 x dilution buffer and incubated at 65°C for 30 minutes. This sample, 60 μl, was put in a 96-well microtiter plate and 60 μl of Assay Buffer and 60 μl of CSPD Chemiluminescent Substrate were added. After 15 minutes of reaction, alkaline phosphatase activity was determined with Luminoscan/RS (LaboSystems ) . Then, to correct for the error due to transfection efficiency, pGV-C2 (Nippon Gene) was transfected simultaneously with the respective expression plasmids and cultured for 72 hours and the cell extract was gently centrifuged and diluted 10-fold. To 20 μl of the dilution was added 100 μl of Pick-a-Gene Luminescent Substrate (Nippon Gene) and the luciferase activity was assayed with Luminoscan/RS (LaboSystems). Therefore, promoter activity was expressed in terms of alkaline phosphatase activity divided by luciferase activity (Luminescence, RLU) . The results are shown in Fig. 9. As can be seen in Fig. 9, whereas the transformant obtained by inserting the plasmid in the reverse direction and the transformant obtained by inserting pSEAP-Basic gene plasmid showed no promoter activity, the transformant obtained using the expression plasmid pTB-2022 showed significant promoter activity. Therefore, the existence of a DNA fragment having functional promoter activity in this genomic DNA fragment was confirmed. Example 5 Immunization and crude purification of rabbit polyclonal antibody The partial peptide [Peptide-I, H- CEDVRGAPYDWRRAPNENGP-OH (SEQ ID NO:39)] and partial peptide [Peptide-II, H-PVIGPLKIREQQRSAVSTC-NH 2 (SEQ ID NO:40)] of human LCAT-like protein were chemically synthesized and conjugated with KLH in the routine manner. Freund's complete adjuvant (FCA) was then admixed with a solution of 500 μg of each peptide in saline to prepare a homogeneous emulsion. Those emulsions were injected subcutaneously at the back of 2 rabbits (NZW) each. Two weeks later, as a booster immunizing dose, a homogeneous emulsion prepared by admixing Freund's incomplete adjuvant (FIA) with a saline solution of each peptide-KLH conjugate was injected subcutaneously at the back of rabbits. The antibody titer was determined as follows . Four weeks after the last immunization, blood was drawn from the auricular vein of rabbits, incubated at 37 °C for 30 minutes, allowed to stand at 4°C for 24 hours, and then centrifuged to harvest an antiserum. The individual antiserum was serially diluted and added in 100 μl aliquots to a polystyrene 96-well microtiter plate coated with saturating levels of the biotinylated form of the peptide I or II immobilized on an avidin coated plate and incubated at 4°C for 24 hours. The antiserum was then discarded, the wells were washed, and HRP-labeled goat anti-rabbit IgG antibody was added and incubated at 20 °C for 1 hour. After the wells were sufficiently washed, the substrate was added for visualization. The enzymatic reaction was stopped by adding 100 μl of the reaction stop solution and by using a microplate colorimeter, the absorbance at 450 nm was measured. The antibodies were prepared as follows. The anti-Peptide I antiserum was loaded onto a Peptide-I- Sepharose 6B column and the anti-Peptide-II antiserum onto a Peptide II-Sepharose 6B column, and after the respective columns were washed with PBS buffer ( 10 mM, pH 7.2 ) and saline, elution was carried out with glycine HCl buffer (100 mM, pH 2.5). Each eluate was neutralized with 0.1 M sodium hydroxide/H 2 0 and used as a purified antibody. Example 6 Localization of LCAT-like protein in a human apolipoprotein fraction by rabbit polyclonal anti-LCAT- like protein-peptide antibodies By using two kind of IgG antibodies prepared by the procedure described in Example 5, the occurrence of LCAT-like protein in human apolipoprotein fractions was investigated. The P 1.063-1.21 g/ml fraction was isolated following preparative ultracentrifugation of human plasma in KBr solution, and dialyzed against TBS buffer (10 mM Tris-HCl, pH 7.4, 150 mM NaCl), and defatted with ethanol/ether . This sample as apoHDL protein (12.8 mg/ml) was checked by Western blotting analysis with the two kind of IgG antibodies. As a result, there was detected a product with a molecular mass of about 50000 which was recognized by both the antibodies (Fig. 10) . For investigating the occurrence in other lipoprotein fractions, human plasma was adjusted for specific gravity with KBr and ultracentrifuged and a fraction less than 1.21 g/ml in density (lipoprotein fraction) was isolated, dialyzed, and purified by FPLC on Superose 6HR (Pharmacia) . The elution pattern is presented in Fig. 11. Each fraction was precipitated with TCA, defatted with acetone, and analyzed by Western blotting using anti-Peptide-II antibody. As a result, as shown in Fig. 12, a product with a molecular weight of about 50000 was detected only in the apoHDL protein fraction and not found in other fractions such as apoVLDL and apoLDL protein fractions . Example 7 Construction of a recombinant DNA for expression of human LCAT-like protein/FLAG fusion gene in insect cells To prepare the protein with FLAG peptide fused at C-terminus, a primer [Primer I, 5'- CCGCTCGAGTCACTTGTCATCGTCGTCGTCCTTGTAGTCGGGCCCAAGGAGCACA CGTTTCAG-3' (SEQ ID N0:41)] which was complementary to the upper strand and consisting of the sequence encoding FLAG peptide and the Xho I linker sequence added at 5 ' -end and a primer [Primer II, 5'- GGAGACAACCAACCGGATCCCAGTCATCGGG-3' (SEQ ID NO: 42)] for the upper strand upstream of BamHI site were constructed and, as shown in Fig. 13, PCR was carried out using Plasmid pTB1973 as the template to obtain a DNA fragment coding for the C-terminal sequence of said protein and its nucleotide sequence was confirmed. Then, a DNA fragment coding for the N-terminal sequence available on EcoRI - BamHI digestion of pTB1973 was prepared and the two fragments were ligated with pFAST Bac I (Gibco BRL) to provide the objective donor plasmid. Example 8 Construction of a recombinant DNA for expression of human LCAT-like protein gene in insect cells A 1.5 kb (approx.) DNA fragment coding for the full length of human LCAT-like protein gene as obtained by digesting plasmid pTB1973 with EcoRI and Xbal was isolated and this fragment was ligated with a similar EcoRI and Xbal digest of pFAST Bac 1 to provide the objective donor plasmid. Example 9 Expression of the human LCAT-like protein/FLAG fusion gene in insect cells Using the donor plasmid described in Example 7, a recombinant virus was acquired from the insect cell line Sf9 in accordance with the manual of Bac-To-Bac Baculovirus Expression System (GIBCO BRL). With m.o.i. (number of virus particles per cell) set to 0.1, Sf9 cells were infected with the recombinant virus and cultured for 3 days. The culture supernatant was recovered and analyzed by Western blotting. As a result, a specific band reacting with both the anti- Peptide II antibody obtained in Example 5 and the anti- FLAG M2 monoclonal antibody (mouse, Cosmo Bio) was identified near the molecular size of 47000. Example 10 Expression of human LCAT-like protein gene in insect cells Using the donor plasmid described in Example 8, a recombinant virus was acquired from the insect cell line Sf9 in accordance with the manual of Bac-To-Bac Baculovirus Expression System (GIBCO BRL). With m.o.i (number of virus particles per cell) set to 0.1, Sf9 cells were infected with the recombinant virus and cultured for 3 days . The culture supernatant was recovered and analyzed by Western blotting. As a result, a specific band reacting with the anti-Peptide II antibody obtained in Example 5 was identified near the molecular size of 45000. Example 11 Purification of human LCAT-like protein/FLAG fusion protein and determination of the N-terminal amino acid sequence One milliliter of the human LCAT-like protein/FLAG fusion protein-producing recombinant virus obtained in Example 9 was added to the insect cell line High Five (2.4xl0 5 cells/ml) grown in 50 ml of Excell 400 (JRH) medium. After this infection, the cells were cultured in a spinner culture flask at 27°C for 3 days. The culture supernatant was recovered (this and subsequent procedures were performed at 4°C), filtered through a 0.22 μm filter to remove the cells and the filtrate was dialyzed against TBS buffer (10 mM Tris-HCl, 150 mM NaCl, pH 7.5) overnight and applied onto an anti-FLAG M2 affinity column (0.7x10 cm) (Cosmo Bio). After the column was washed with 30 ml of TBS buffer, elution was carried out with solutions of FLAG peptide in TBS buffer (25-75 μg/ml) to provide about 170 μg of the objective protein. A portion of this solution was subjected to SDS-PAGE and stained with CBB . As a result, the protein was detected as a single band near a molecular size of 47000 in agreement with the band detected by Western blotting analysis using anti-FLAG M2 monoclonal antibody. Another portion of the above solution was subjected to SDS-PAGE and transferred onto an PVDF (polyvinylidene difluorile) membrane (MILLIPORE) and the amino acid sequence was determined. Analysis with Peptide Sequencer (HP G1005A) gave SEQ ID NO:43 (AGRHPPWLV) , indicating that the N-terminal sequence of this protein was identical to the sequence available upon cleavage between the 33rd and 34th positions of the precursor protein of SEQ ID NO: 6. Example 12 Crude purification of human LCAT-like protein One milliliter of the human LCAT-like protein- producing recombinant virus obtained in Example 10 was added to the insect cell line High Five (2.0x10 cells/ml) cultured in 50 ml of Excell 400 (JRH) medium. After this infection, the cells were cultured in a spinner culture flask at 27°C for 3 days. The culture supernatant was recovered (this and subsequent procedures were carried out at 4°C), filtered through a 0.22 μm filter to remove cells and the filtrate was dialyzed against the buffer (4 mM sodium phosphate, 0.5 M NaCl, pH 7.4) overnight and loaded onto a Phenyl- Sepharose HP column (1.5x10 cm) (Pharmacia) equilibrated with the same buffer. After the column was washed with 100 ml of the same buffer, the objective protein was eluted in 2 ml fractions using about 25 ml of water. The elution patterns detected by UV absorbance and analyzed by Western blotting using anti-Peptide II antibody are shown in Fig. 14. It is clear that the product reacting with the antibody obtained in Example 5 (a molecular size of about 45000) was concentrated in the eluate. Example 13 Assay of the esterase activities of human LCAT-like protein/FLAG fusion protein and human LCAT-like protein using a fatty acid ester Assays were carried out in accordance with the method of Bonelli, F.S. and Jonas, A. [Journal of Biological Chemistry, 2_±, 14723-14728, 1989]. Thus, to the reaction buffer (10 mM Tris, pH 7.4, 150 mM NaCl, 0.01% EDTA, 1 mM NaN 3 ) was added a graded solution of p-nitrophenyl butyrate (PNPB) in acetonitrile (final concentration: 5 mM - 50 μM) as the substrate. Then, the human LCAT-like protein/FLAG fusion protein obtained in Example 9 was added (final concentration: 3.4 μg/ml) to make 1 ml. The mixture was incubated at 37 °C for 20 minutes and the absorbance at 400 nm was measured at 2-minute intervals. The results are shown in Fig. 15. From the percent changes in absorbance at the respective substrate concentrations, initial velocity was calculated, and according to the Lineweaver-Burk method, Vmax and Km were calculated (Fig. 16). Both the values agreed with the values of human plasma LCAT on an order basis. Using 50 μl of the semi-purified enzyme solution of fractions 6 and 7 ( 4 ml ) obtained in Example 12 (Fig. 14), a similar activity assay was carried out at a substrate concentration of 100 μM. As a result, the above enzyme solution was confirmed to have esterase activity (Fig. 17) . Example 14 Influence of DFP and DTNB on the esterase activity of human LCAT-like protein/FLAG fusion protein as assayed with PNPB Prior to addition of the substrate in the procedure of Example 13, DFP (diisopropyl fluorophosphate) or DTNB ( 5 , 5 ' -dithiobis ( 2-nitrobenzoic acid) ] was added to the reaction mixture without the substrate and the system was incubated at 25 °C for 1 hour to investigate whether the activity was inhibited or not. The substrate concentration was 500 μM and the final concentration of human LCAT-like protein/FLAG fusion protein was 3.4 μg/ml. As a result, the activity was inhibited by both the inhibitors (Fig. 18), suggesting that both serine and cysteine residues are associated with this esterase activity.
