     DETAILED DESCRIPTION 
     For the purposes of this application, the terms listed below shall have the following meaning: 
     enzymatically active segment 
     A segment of a multifunctional protein having activity comprising at least one of a chymotrypsin, trypsin, collagenase, elastase or exo peptidase activity. 
     hydrolase 
     An enzyme that degrades bonds formed by dehydration reactions such as amide, ester, or ether bonds. The term encompasses, but is not limited to, proteases such as trypsin and chymotrypsin. 
     isoform 
     A naturally occurring sequence variant of a substantially homologous protein within the same organism. Preferably, the isoform shares at least about 80% identity, and more preferably, at least about 85% identity with SEQ. ID NO:4. 
     krill-derived multifunctional protein 
     A multifunctional protein having the same sequence as a protein isolated from krill having the properties of the protein described in the section entitled &#34;Preferred Characteristics of the Multifunctional Protein.&#34; This protein is also referred to as the &#34;krill-derived multifunctional hydrolase&#34; and includes all isoforms of the protein. The amino acid sequence included in SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:8 or SEQ ID NO:10 or other isoforms thereof or chimeric polypeptides thereof are examples of krill-derived multifunctional proteins. 
     multifunctional protein 
     A protein having activity comprising at least one of a chymotrypsin, trypsin, collagenase, elastase or exo peptidase activity or asialo GM 1  ceramide binding activity, and substantial homology to at least a segment of a krill-derived multifunctional protein. 
     substantial homology 
     At least about 60% sequence homology. 
     The present invention provides DNA and corresponding amino acid sequences of a krill-derived multifunctional protein that has been found to be useful in numerous medical and cosmetic contexts. Crustaceans, including antarctic krill, are useful sources for the multifunctional protein of the invention. A protein having &#34;multifunctional activity,&#34; is defined herein as including at least one of a chymotrypsin, trypsin, collagenase, elastase or exo peptidase activity, or asialo GM 1  ceramide binding activity. For purification of krill-derived multifunctional protein, see, for example, U.S. patent application Ser. No.08/600,273 (filed Feb. 8, 1996), deFaire et al., inventors, entitled &#34;Multifunctional Enzyme,&#34; relevant portions of which are hereby incorporated by reference. 
     The present invention provides nucleic acids and polypeptides and analogs thereof, including nucleic acids that bind to a multifunctional protein encoding nucleic acid, as well as pharmaceutical compositions, gene therapy and antibodies and antisera against the multifunctional protein. Some of the nucleic acids and polypeptides are naturally occurring variants (isoforms) whereas others are non-naturally occurring (engineered) variants. 
     1. Nucleic Acids 
     The nucleic acid embodiments of the invention are preferably deoxyribonucleic acids (DNAs), both single- and double-stranded, and most preferably double-stranded deoxyribonucleic acids. However, they can also be ribonucleic acids (RNAs), as well as hybrid RNA:DNA double-stranded molecules. 
     Nucleic acids encoding a multifunctional protein include all multifunctional protein-encoding nucleic acids, whether native or synthetic, RNA, DNA, or cDNA, that encode a multifunctional protein, or the complementary strand thereof, including but not limited to nucleic acid found in a multifunctional protein-expressing organism. For recombinant expression purposes, codon usage preferences for the organism in which such a nucleic acid is to be expressed are advantageously considered in designing a synthetic multifunctional protein-encoding nucleic acid. 
     The nucleic acid sequences of the invention can encode, for example, one of several isoforms of a krill-derived protein. SEQ ID NO:4, SEQ ID NO:5 and SEQ ID NO:8 represent three isoforms that share about 88-89% identity with each other in overlapping amino acids. See, for example, FIG. 1 which compares the DNA sequence of the first isoform, SEQ ID NO:1, with the DNA sequence of the second isoform, SEQ ID NO:2, which share about 88% identical nucleotides. See also, for example, FIG. 3, which provides a comparison of the DNA sequence of the third isoform (SEQ ID NO:7) and the first isoform (SEQ ID NO:1), which share about 89% identical nucleotides. 
     These isoforms all lack the initiation codon methionine. Further, two of these three isoforms contain a hydrophobic sequence which may function as a signal sequence, namely, LLLALVAAASA, which is amino acid residues 1-11 in the first isoform, SEQ ID NO:4, and PGRSRIALLLALVAATASA, which is amino acid residues 1-19 in the third isoform, SEQ ID NO:8. These two isoforms additionally contain a pro-protein segment. The pro-protein segment is the segment of the protein, other than the hydrophobic segment, that is present in the precursor protein but absent in the mature protein. Without being limited to a particular theory, it is possible that at least a part of the pro-protein segment may still be attached to the mature protein. Further, it is believed that krill-derived multifunctional proteins may have two chains linked by a disulfide bond. For example, a cysteine in the pro-protein segment may participate in a disulfide bond in the mature protein. 
     In the first isoform, the pro-protein segment has the following sequence, which corresponds to amino acid residues 12-63 in the first isoform, SEQ ID NO:4: AEWRWQFRHPTVTPNPRAKNPFRVTKSSPV QPPAVRGTKAVENCGPVAPRNK. The third isoform has a pro-protein segment with the following sequence, which corresponds to amino acid residues 20-71 in SEQ ID NO:8: SEWRWQFRHPTVTPNPRANNPFR PSKVAPVQPPAVRGTKAVENCGPVAPKNK. The remaining amino acid sequences of these polypeptides (other than the hydrophobic segment and the pro-protein segment) represent the mature protein. See FIG. 2, which provides a comparison of the amino acid sequence of the first isoform and the second isoform, which share about 89% identical amino acids. Additionally, see FIG. 4 which provides a comparison of the amino acid sequences of all three isoforms. 
     Further embodiments of the invention include nucleic acid sequences that encode polypeptides that are preferably present in the protein. The following examples are derived from the pro-protein segment of SEQ ID NO:4, and are polypeptides that are preferably present in the mature protein. Without being limited to a particular theory, these polypeptides may form at least part of a first amino acid chain that is linked via a disulfide bond to a second amino acid chain, which can be, for example, the mature protein. For instance, in certain preferred embodiments, the nucleic acid further encodes a polypeptide sequence such as AVENCGPVAPR (SEQ ID NO:11), AVENCGPVAPRNK (SEQ ID NO:12), GTKAVENCGPVAPR (SEQ ID NO:13), GTKAVENCGPVAPRNK (SEQ ID NO:14), SSPVQPPAVRGTKAVENCGPVAPR (SEQ ID NO:15), or SSPVQPPAVRGTKAVENCGPVAPRNK (SEQ ID NO:16). Without being limited to a particular theory, the above-listed polypeptides (SEQ ID NO:11-16) may be linked to the remainder of the mature krill-derived multifunctional protein via a disulfide bond as follows. For example, the cysteine residue in one of these sequences (SEQ ID NO:11-16) may participate in a disulfide bond with, for example, a cysteine in the mature protein, such as a cysteine corresponding the cysteine at residue 171 of SEQ ID NO:4. At least one of these sequences (SEQ ID NO:11-16) are therefore present in preferred embodiments of the invention. See, for example, FIG. 5, which shows the amino acid sequences of several proteins, namely, Factor VII, thrombin, kallikrein, a Limulus pro-clotting enzyme from the Japanese horshoe crab (Tachypleus tridentatus), plasmin, hepsin and Factor XII, aligned with the amino acid sequence of SEQ ID NO:4. All of the proteins aligned with the krill-derived multifunctional protein, except for the Limulus protein and Hepsin, are involved in the human blood coagulation pathway. 
     Without being limited to any particular theory, it is believed that krill-derived multifunctional proteins include a larger N-terminus than that found in the first, second or the third isoform, SEQ ID NO:4, SEQ ID NO:5 or SEQ ID NO:8, respectively. 
     The nucleic acids of the invention can encode engineered multifunctional proteins based on forming chimeric polypeptides from the above isoforms, for example. The hydrophobic sequence or the pro-protein segment of one naturally occurring isoform can optionally be matched with the mature protein sequences of another naturally occurring isoform or isoforms. For example, the mature protein segment of SEQ ID NO:4 is amino acids 64-300. SEQ ID NO:5, for instance, is a partial sequence of the second isoform, which has a mature protein sequence of about 75% of the length of the mature protein segment of SEQ ID NO:4. Therefore, certain embodiments of the invention include a chimeric polypeptide in which the N-terminus of the polypeptide of SEQ ID NO:5 is linked to the remaining 25% of the length of the mature protein sequence found in SEQ ID NO:4, namely amino acids 64-116. In another embodiment of the invention, a hypothetical chimeric sequence includes the first 63 amino acids of the protein of SEQ ID NO:4 together with the amino acid sequence of SEQ ID NO:5. See SEQ ID NO:6, which is a composite of the proteins of SEQ ID NO:4 and SEQ ID NO:5. See, for example, FIG. 2, which aligns SEQ ID NO:4 with SEQ ID NO:5. The nucleic acid sequence corresponding to the amino acid sequence of SEQ ID NO:6 is provided in SEQ ID NO:3, which provides the first 344 nucleic acids of SEQ ID NO:1 together with the nucleic acid sequence of SEQ ID NO:2. 
     Thus, the nucleic acids of the invention include nucleic acids that code for the mature protein, the protein including the pro-protein segment or the protein including the hydrophobic segment and the pro-protein segment, or portions thereof. For example, the nucleic acid of the first isoform, SEQ ID NO:1, or the chimeric molecule, SEQ ID NO:3, are nucleic acids encoding the pro-protein, including the hydrophobic sequence and the pro-protein segment. The chimeric molecule, SEQ ID NO:3, represents the first 344 nucleotides of SEQ ID NO:1, coding for the hydrophobic sequence and the pro-protein segment of the protein and the first 25% of the mature protein, together with the 599 nucleotides of SEQ ID NO:2, coding for the remaining 75% of the mature protein. 
     Further, for example, the N-terminus of SEQ ID NO:8 can be attached to the mature protein sequences of SEQ ID NO:5, thereby forming a chimeric polypeptide, shown in SEQ ID NO:10. The corresponding DNA sequence can be found in SEQ ID NO:9. 
     Alternatively, for example, amino acid sequence of isoforms can be used to create an engineered polypeptide. For example, the chimeric polypeptide of SEQ ID NO:6 can be further modified by adding to the N-terminus of the protein the amino acid sequence PGRSRIA, which is amino acid residues 1-7 from the N-terminus of the third isoform, SEQ ID NO:10. 
     Without being bound to a particular theory, it is believed that there are at least about 4 isoforms, each having a different amino acid at the position corresponding to amino acid residue 68 of SEQ ID NO:4, including glutamine, methionine, lysine and asparagine. Such isoforms and other homologous polypeptides can be isolated using the techniques described under Section 5 below, entitled &#34;Means for Identifying Polypeptides with Multifunctional Activity.&#34; 
     To construct engineered variants of multifunctional protein-encoding nucleic acids, the native sequences of any of the isoforms can be used as a starting point and modified to suit particular needs. For example, in certain embodiments, the nucleic acid sequence need not include the sequences encoding the 5&#39; portion of the amino acid sequence that is absent in the mature protein, including amino acids 1-63 of SEQ ID NO:4. Thus, in certain embodiments of the invention, the encoded polypeptide is homologous to or has the sequence of the mature protein only, and not the segments corresponding to the N-terminal portions that are removed during cellular processing, namely, the hydrophobic sequence and the pro-protein segment. 
     Nonetheless, in preferred embodiments of the nucleic acids of the invention, the sequences encoding the N-terminal portion of the amino acid sequence that is absent in the mature protein, including amino acids 1-63 of SEQ ID NO:4, are included in the nucleic acid sequences. 
     The amino acid sequence forming a synthetic multifunctional protein preferably includes an enzymatically active segment of a krill-derived multifunctional protein, such as amino acids 64-300 of SEQ ID NO:4, particularly including the histidine at residue 104, the aspartic acid at residue 151 and the serine at residue 246, which are implicated in the catalytic mechanism of serine proteases. Thus, the protein need not include the hydrophobic sequence or pro-protein segment that are present in a krill-derived protein before cellular processing occurs, although the hydrophobic sequence and the pro-protein segment are preferably present. 
     Preferably, the nucleic acids will encode polypeptides having at least about 70% homology, more preferably, at least about 80% homology, even more preferably, at least about 85% homology, yet more preferably at least about 90% homology, and most preferably at least about 95% homology to a krill-derived multifunctional protein, such as the polypeptides of SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:8 or SEQ ID NO:10, or amino acid sequences 64-300 of SEQ ID NO:4, or other naturally occurring isoforms. Even more preferably, the nucleic acids will encode polypeptides sharing at least about 70% identity, more preferably, at least about 80% identity, yet more preferably, at least about 85% identity, still more preferably at least about 90% identity, and most preferably at least about 95% identity with a krill-derived multifunctional protein. 
     Additionally, the invention includes a substantially pure nucleic acid comprising a nucleic acid that binds to a nucleic acid encoding a polypeptide having at least about 70% homology to a krill-derived multifunctional protein. Even more preferably, the nucleic acid binds to a nucleic acid encoding a polypeptide having at least about 80% homology, and more preferably, at least about 90% homology to a krill-derived multifunctional protein. Yet more preferably, the nucleic acid binds to a nucleic acid encoding a polypeptide sharing at least about 70% amino acid identity, and more preferably, at least about 80% amino acid identity, and yet more preferably, at least about 90% amino acid identity with a krill-derived multifunctional protein, such as the polypeptide of SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:8 or SEQ ID NO:10 and especially, SEQ ID NO:4, SEQ ID NO:6 or SEQ ID NO:10. A nucleic acid that binds to a nucleic acid that encodes a polypeptide homologous to a krill-derived multifunction protein can be used as a probe, for example, to identify additional multifunctional proteins or to determine multifunctional protein expression. 
     Numerous methods for determining percent homology are known in the art. One preferred method is to use version 6.0 of the GAP computer program for making sequence comparisons. The program is available from the University of Wisconsin Genetics Computer Group and utilizes the alignment method of Needleman and Wunsch, J. Mol. Biol. 48, 443, 1970, as revised by Smith and Waterman Adv. Appl. Math. 2, 482, 1981. Numerous methods for determining percent identity are also known in the art, and a preferred method is to use the FASTA computer program, which is also available from the University of Wisconsin Genetics Computer Group. 
     The mature protein of the polypeptide of SEQ ID NO:4 is about 61 % identical to the chymotrypsin-like serine proteinase in the shrimp Penaeus vannamei according to the sequence provided by Genbank (Mountain View, Calif.), database acquisition no. X66415, and about 60% identical to the collagenolytic serine proteinase in the fiddler crab Uca pugilator, according to the sequence provided by Genbank, database acquisition no. U49931. The amino acid sequence of the pro-protein of SEQ ID NO:4 is about 53% identical to the precursor of the chymotrypsin-like serine proteinase in the shrimp Penaeus vannamei, and about 51 % identical to the precursor of the collagenolytic serine proteinase in the fiddler crab Uca pugilator. Preferably, the nucleic acids encoding polypeptides having multifunctional activity are less than about 70% identical to the above-identified proteinases of Penaeus vannamei or Uca pugilator. 
     In addition to nucleic acids encoding a multifunctional protein, the present invention includes nucleic acids encoding polypeptides that are homologous to a krill-derived multifunctional protein or that share a percentage identity with a krill-derived multifunctional protein. Further, the present invention includes nucleic acids that encode a portion of a multifunctional protein or a variant thereof, such as the enzymatically active portion of the protein or the portion of the protein that provides asialo GM 1  ceramide binding activity. 
     The invention also is directed to a nucleic acid encoding a krill-derived multifunctional protein that has at least one of the following activities: chymotrypsin, trypsin, collagenase, elastase and exopeptidase activity or asialo GM 1  ceramide binding activity. Preferably, the encoded polypeptide will be effective to remove or inactivate a cell-surface adhesion molecule, and most preferably, the encoded polypeptide will be pharmaceutically effective. 
     For identifying the active segment or segments of multifunctional protein, one approach is to take a multifunctional protein cDNA and create deletional mutants lacking segments at either the 5&#39; or the 3&#39; end by, for instance, partial digestion with S1 nuclease, Bal 31 or Mung Bean nuclease (the latter approach described in literature available from Stratagene, San Diego, Calif., in connection with a commercial deletion cloning kit). Alternatively, the deletion mutants are constructed by subcloning restriction fragments of a multifunctional protein cDNA. The deletional constructs are cloned into expression vectors and tested for their multifunctional activity. 
     These structural genes can be altered by mutagenesis methods such as that described by Adelman et al., DNA, 2: 183, 1983 or through the use of synthetic nucleic acid strands. The products of mutant genes can be readily tested for multifunctional activity. 
     The nucleic acid sequences can be further mutated, for example, to incorporate useful restriction sites. See Maniatis et al. Molecular Cloning, a Laboratory Manual (Cold Spring Harbor Press, 1989). Such restriction sites can be used to create &#34;cassettes&#34;, or regions of nucleic acid sequence that are facilely substituted using restriction enzymes and ligation reactions. The cassettes can be used to substitute synthetic sequences encoding mutated multifunctional protein amino acid sequences. 
     The multifunctional protein-encoding sequence can be, for instance, substantially or fully synthetic. See, for example, Goeddel et al., Proc. Natl. Acad. Sci. USA, 76, 106-110, 1979. For recombinant expression purposes, codon usage preferences for the organism in which such a nucleic acid is to be expressed are advantageously considered in designing a synthetic multifunctional protein-encoding nucleic acid. Since the nucleic acid code is degenerate, numerous nucleic acid sequences can be used to create the same amino acid sequence. 
     Further, with an altered amino acid sequence, numerous methods are known to delete sequence from or mutate nucleic acid sequences that encode a polypeptide and to confirm the function of the polypeptides encoded by these deleted or mutated sequences. Accordingly, the invention also relates to a mutated or deleted version of a multifunctional protein nucleic acid that encodes a polypeptide that retains multifunctional protein activity. 
     Conservative mutations of the naturally occurring isoforms are preferred for engineered variants. Such conservative mutations include mutations that switch one amino acid for another within one of the following groups: 
     1. Small aliphatic, nonpolar or slightly polar residues: Ala, Ser, Thr, Pro and Gly; 
     2. Polar, negatively charged residues and their amides: Asp, Asn, Glu and Gln; 
     3. Polar, positively charged residues: His, Arg and Lys; 
     4. Large aliphatic, nonpolar residues: Met, Leu, Ile, Val and Cys; and 
     5. Aromatic residues: Phe, Tyr and Trp. 
     A preferred listing of conservative substitutions is the following: 
     
         ______________________________________Original Residue     Substitution______________________________________Ala                  Gly, Ser  Arg Lys  Asn Gln, His  Asp Glu  Cys Ser  Gln Asn  Glu Asp  Gly Ala, Pro  His Asn, Gln  Ile Leu, Val  Leu Ile, Val  Lys Arg, Gln, Glu  Met Leu, Tyr, Ile  Phe Met, Leu, Tyr  Ser Thr  Thr Ser  Trp Tyr  Tyr Trp, Phe  Val Ile, Leu______________________________________ 
    
     The types of substitutions selected may be based on the analysis of the frequencies of amino acid substitutions between homologous proteins of different species developed by Schulz et al., Principles of Protein Structure, Springer-Verlag, 1978, pp. 14-16, on the analyses of structure-forming potentials developed by Chou and Fasman, Biochemistry 13, 211, 1974 or other such methods reviewed by Schulz et al, Principles in Protein Structure, Springer-Verlag, 1978, pp. 108-130, and on the analysis of hydrophobicity patterns in proteins developed by Kyte and Doolittle, J. Mol. Biol. 157: 105-132, 1982. 
     2. Polypeptides 
     Polypeptides of the invention include all polypeptides having multifunctional activity, whether native or synthetic, including but not limited to polypeptides purified from a multifunctional protein-expressing organism. A preferred embodiment of the invention provides a polypeptide comprising a substantially pure isoform of a krill-derived multifunctional protein or engineered variant thereof, and more preferably, a polypeptide comprising SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:8 or SEQ ID NO:10 and especially, SEQ ID NO:4, SEQ ID NO:6 or SEQ ID NO:10. Further, polypeptides of the invention preferably comprise at least one of the amino acid sequences of SEQ ID NO:11-16. 
     In addition to the multifunctional protein and its isoforms and portions thereof, the present invention includes polypeptides that are homologous to a krill-derived multifunctional protein or that share a percentage identity with a krill-derived multifunctional protein. Further, the present invention includes portions of the multifunctional protein or a variant thereof, such as the enzymatically active portion of the protein or the portion of the protein that provides asialo GM 1  ceramide binding activity. 
     Additionally, the present invention includes engineered variants of multifunctional proteins that retain multifunctional activity. In certain embodiments, these engineered variants lack, for example, no more than about 63 amino acid residues at the N-terminal end of SEQ ID NO:4. 
     Preferably, the variants will have at least about 70% homology, more preferably, at least about 80% homology, even more preferably, at least about 85% homology, still more preferably at least about 90% homology, and most preferably at least about 95% homology to a krill-derived multifunctional protein, such as the polypeptides of SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, or other isoforms, or amino acid sequences 64-300 of SEQ ID NO:4. Even more preferably, the analogs will share at least about 70% identity, more preferably, at least about 80% identity, yet more preferably, at least about 85% identity, still more preferably at least about 90% identity, and most preferably at least about 95% identity with a krill-derived multifunctional protein. 
     Preferably, the polypeptide has the sequence of a contiguous stretch of at least about 237 amino acids of the following mature proteins: in SEQ ID NO:4, amino acid residues 64-300; in SEQ ID NO:6, amino acid residues 64-300; and in SEQ ID NO:10, amino acid residues 72-308. 
     Amino acid analogs of the above-described polypeptides are also included in the present invention. 
     Additionally, the present invention provides a pharmaceutical composition for treating an animal comprising an effective amount of a polypeptide comprising a substantially pure isoform of a krill-derived multifunctional protein or engineered variant thereof and a pharmaceutically acceptable carrier. More preferably, the polypeptide comprises SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:8 or SEQ ID NO:10, and even more preferably, SEQ ID NO:4, SEQ ID NO:6 or SEQ ID NO:10, and the polypeptide preferably comprises at least one of the amino acid sequences of SEQ ID NO:11-16. 
     3. Methods of Synthesizing Polypeptides 
     In one embodiment, the polypeptides of the invention are made as follows, using a gene fusion. For example, fusion to maltose-binding protein (&#34;MBP&#34;) can be used to facilitate the expression and purification of a multifunctional protein in a prokaryote such as E. coli. The hybrid protein can be purified, for example, using affinity chromatography using the binding protein&#39;s substrate. See, for example, Gene 67: 21-30 (1988). When using a fusion protein that includes maltose binding protein, a cross-linked amylose affinity chromatography column can be used to purify the protein. 
     The cDNA specific for a given multifunctional protein or analog thereof can also be linked using standard means to a cDNA for glutathione s-transferase (&#34;GST&#34;), found on a commercial vector, for example. The fusion protein expressed by such a vector construct includes the multifunctional protein or analog and GST, and can be treated for purification. 
     Should the MBP or GST portion of the fusion protein interfere with function, it is removed by partial proteolytic digestion approaches that preferentially attack unstructured regions, such as the linkers between MBP or GST and the multifunctional protein. The linkers are designed to lack structure, for instance using the rules for secondary structure-forming potential developed by Chou and Fasman, Biochemistry 13, 211, 1974. The linker is also designed to incorporate protease target amino acids, such as trypsin, arginine and lysine residues. To create the linkers, standard synthetic approaches for making oligonucleotides are employed together with standard subcloning methodologies. Other fusion partners other than GST or MBP can also be used. 
     Additionally, the multifunctional proteins can be directly synthesized from nucleic acid (by the cellular machinery) without use of fusion partners. For instance, nucleic acids having the sequence of SEQ ID NO:1, SEQ ID NO:3 or SEQ ID NO:9 are subcloned into an appropriate expression vector having an appropriate promoter and expressed in an appropriate organism. Antibodies against multifunctional protein can be employed to facilitate purification. 
     Additional purifications techniques are applied as needed, including without limitation, preparative electrophoresis, FPLC (Pharmacia, Uppsala, Sweden), HPLC (e.g., using gel filtration, reverse-phase or mildly hydrophobic columns), gel filtration, differential precipitation (for instance, &#34;salting out&#34; precipitations), ion-exchange chromatography and affinity chromatography (including affinity chromatography using the RE1 duplex nucleotide sequence as the affinity ligand). 
     A polypeptide or nucleic acid is &#34;isolated&#34; in accordance with the invention in that the molecular cloning of the nucleic acid of interest, for example, involves taking a multifunctional protein nucleic acid from a cell, and isolating it from other nucleic acids. This isolated nucleic acid may then be inserted into a host cell, which may be yeast or bacteria, for example. A polypeptide or nucleic acid is &#34;substantially pure&#34; in accordance with the invention if it is predominantly free of other polypeptides or nucleic acids, respectively. A macromolecule, such as a nucleic acid or a polypeptide, is predominantly free of other polypeptides or nucleic acids if it constitutes at least about 50% by weight of the given macromolecule in a composition. Preferably, the polypeptide or nucleic acid of the present invention constitutes at least about 60% by weight of the total polypeptides or nucleic acids, respectively, that are present in a given composition thereof, more preferably about 80%, still more preferably about 90%, yet more preferably about 95%, and most preferably about 100%. Such compositions are referred to herein as being polypeptides or nucleic acids that are 60% pure, 80% pure, 90% pure, 95% pure, or 100% pure, any of which are substantially pure. 
     4. Preferred Characteristics of the Multifunctional Protein 
     Krill, including without limitation krill of the genuses Euphasia (such as superba, crystallorphias, frigida, triacantha, vellantini, lougirostris, lucens, similis, spinifera, recurva and the like), Meganyctiphanes (such as norvegica and the like) and Tysanoessa (such as macurura, vicina, gregaria and the like), are a preferred source of krill-derived multifunctional proteins. 
     Preferably, the protein has a molecular weight between about 20 kd and about 40 kd, and more preferably from about 26 kd to about 32 kd, and most preferably about 29 kd, as determined by sodium dodecyl sulfate (&#34;SDS&#34;) polyacrylamide gel electrophoresis (&#34;PAGE&#34;). Further, the protein preferably has substantial homology to a krill-derived multifunctional protein. Preferred proteins are hydrolases, and preferably, proteases. Preferably, the protein is selectively reactive with cell-surface receptors such as polypeptides or glycolipids. 
     Protease activity can be determined by incubating a protein preparation with casein (concentration 1 % w/v) at 30° C. for 20 hours and measuring the release of amino acids or peptides (which can be measured by the increase in colorometrically determinable amino groups). Isolated multifunctional protein of 95% purity will typically have a specific activity of at least about 25 Casein Units per mg. Casein Units are defined in Biochem. J., 173: 291-298, 1978 (using azocasein as the substrate). 
     Alternatively, tryptic protease activity can be measured against tyrosine-arginine-methyl-ester (&#34;TAME&#34;). The multifunctional protein (of at least about 95% purity) will preferably have specific activity of at least about 60 TAME Units per mg. Or, tryptic activity can be measured using Benzoyl-Val-Gly-Arg-p-NO 2  -anilide as the substrate. Using this substrate and the method of Biochemical J., 185: 423-433, 1980, the multifunctional protein will preferably have specific activity of at least about 210 Units per mg. Chymotryptic activity can be measured using Succinyl-Ala-Ala-Pro-Phe-p-NO 2  -anilide as the substrate. Using this substrate and the method of J. Biol. Chem., 269: 19565-19572, 1994, the multifunctional protein will preferably have specific activity at least about 260 Units per mg. Elastase activity can be measured using Boc-Ala-Ala-Pro-Ala-p-NO 2  -anilide as the substrate. Using this substrate and the method of J. Biol. Chem., 269: 19565-19572, 1994, the multifunctional protein will preferably have specific activity of at least about 270 Units per mg. 
     Generally, the multifunctional protein will be sufficiently stable so that at least about 50% of the proteolytic activity is retained after incubation at 50° C. for 24 hours at pH 7.0 at a concentration of 5 mg/ml. Preferably at least about 50% of the proteolytic activity is retained after incubation at 60° C. for 5 hours at pH 7.0 at a concentration of 5 mg/ml. 
     Preferably, the pH optimum of the multifunctional protein is substrate dependent. For the substrate azocasein, the pH optimum is preferably from about 3.5 to about 6.5, more preferably, from about 4.0 to about 6.0. For the substrate Benzoyl-Val-Gly-Arg-p-nitroanilide, the pH optimum is preferably in excess of about 8.0, more preferably in excess of about 9.0. For the substrate Boc-Ala-Ala-Pro-Ala-p-nitroanilide, the pH optimum is preferably between about 6.0 and about 7.0, more preferably about 7.0. 
     Using Benzoyl-Val-Gly-Arg-p-nitroanilide as the substrate, the K m  at about pH 9.5 in the presence of 2 mM Ca 2+   is preferably between about 200 and about 240 μM. Using Succinyl-Ala-Ala-Pro-Phe-p-nitroanilide as the substrate, the K m  at pH 9.5 in the presence of 2 mM Ca 2  + is preferably between about 250 and about 290 μM. 
     Preferably, the multifunctional protein has a temperature optimum for activity against casein of between about 45° C. and about 60° C. Generally, the protein retains at least about 50% of its activity when incubated at 5 mg/ml for 18 hours at a pH ranging from about 5.0 to about 9.5 at 25° C. 
     When HL60 cells are pretreated with krill-derived multifunctional hydrolase, their binding to TNFα stimulated endothelial cells is inhibited by more than about 60%. Preferably, treatment of HL60 or endothelial cells with the multifunctional protein of the invention will inhibit HL60 cell binding to TNFα stimulated endothelial cells by at least about 20%, more preferably at least about 40%, still more preferably at least about 60%, yet more preferably at least about 80%. Alternately, the multifunctional protein will preferably have at least about 30% of the adhesion-inhibiting activity of the krill-derived multifunctional hydrolase. More preferably, the multifunctional protein shall have at least about 60% of the adhesion inhibiting activity of the krill-derived multifunctional hydrolase, still more preferably at least about 80%, yet more preferably at least about 100%. 
     The multifunctional protein of the invention effectively removes or inactivates certain cell-surface adhesion molecules, such as ICAM-1 (i.e., CD 54), ICAM-2, VCAM-1, CD4, CD8, CD28, CD31, CD44 and the asialo GM 1  ceramide, without affecting cell viability. This adhesion site removal or inactivation phenomenon is believed to provide at least a partial explanation for the protein&#39;s effectiveness against many, though probably not all, of the indications against which the multifunctional protein is effective as a treatment or preventative agent. Other cell surface receptors have been found to be substantially resistant to removal or inactivation by the multifunctional protein, such as the T-cell receptor, the Class I major histocompatibility complex or the integrins CD11 and CD18. 
     5. Means for Identifying Polypeptides with Multifunctional Activity 
     In one aspect, the present invention provides methods for identifying polypeptides that are homologous to the multifunctional protein. Such polypeptides may be found, for example, in fish and crustaceans. 
     The method by which multifunctional protein cDNA was isolated illustrates how readily multifunctional proteins are identified. For instance, see Example 1. The same methodology can be used to identify other sequences from other sources that have multifunctional activity. 
     Additionally, probes for multifunctional protein expression can be used, for example, to detect the presence of a multifunctional protein. Such probes include antibodies directed against multifunctional protein or fragments thereof, nucleic acid probes that hybridize to multifunctional protein mRNA under stringent conditions, and oligonucleotides that specifically prime a PCR amplification of multifunctional protein mRNA. Nucleic acid molecules that bind to a multifunctional protein-encoding nucleic acid under high stringency conditions are identified functionally, or by using the hybridization rules reviewed in Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Press, 1989. 
     Many deletional or mutational analogs of nucleic acid sequences for a multifunctional protein are effective hybridization probes for multifunctional protein-encoding nucleic acid. Accordingly, the present invention relates to nucleic acids that hybridize with such multifunctional protein-encoding nucleic acids under stringent conditions. Preferably, the nucleic acid of the present invention hybridizes with at least a segment of the nucleic acid described as SEQ ID NO:1 SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:7 or SEQ ID NO:9 under stringent conditions. 
     &#34;Stringent conditions&#34; refers to conditions that allow for the hybridization of substantially related nucleic acids, where relatedness is a function of the sequence of nucleotides in the respective nucleic acids. For instance, for a nucleic acid of 100 nucleotides, such conditions will generally allow hybridization thereto of a second nucleic acid having at least about 85% homology, and more preferably having at least about 90% homology. Such hybridization conditions are described by Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Press, 1989. Hybridization can be conducted as follows: Add the probe to the prehybridization solution. Prehybridization solution includes 50% formamide and 6× SSC. Virtually complete suppression of background hybridization is obtained by prehybridizing filters with a blocking agent consisting of 5× Denhardt&#39;s reagent, 0.5% SDS, and 100 μg/ml denatured, fragmented, salmon sperm DNA. Thus, prehybridization solution can include 50% formamide, 6× SSC, 5× Denhardt&#39;s reagent, 0.5% SDS, and 100 μg/ml denatured, fragmented, salmon sperm DNA. If the experiment demands washing at high stringencies, wash by immersing in 0.2× SSC and 0.1% SDS at 68° C. 
     PCR (polymerase chain reaction) can be used to detect nucleic acids having multifunctional protein sequences through amplification of such sequences using multifunctional protein nucleic acid primers. PCR methods of amplifying nucleic acids utilize at least two primers. One of these primers is capable of hybridizing to a first strand of the nucleic acid to be amplified and of priming protein-driven nucleic acid synthesis in a first direction. The other is capable of hybridizing the reciprocal sequence of the first strand (if the sequence to be amplified is single stranded, this sequence is initially hypothetical, but is synthesized in the first amplification cycle) and of priming nucleic acid synthesis from that strand in the direction opposite the first direction and towards the site of hybridization for the first primer. Conditions for conducting such amplifications, particularly under preferred high stringency conditions, are well known. See, for example, PCR Protocols, Cold Spring Harbor Press, 1991. 
     Antibodies against multifunctional proteins can also be used to identify polypeptides that are homologous to multifunctional protein. Antigens for eliciting the production of antibodies against the multifunctional protein can be produced recombinantly by expressing all of or a part of the nucleic acid of a multifunctional protein in a prokaryote such as bacteria or a eukaryote such as yeast. In one embodiment, the recombinant protein is expressed as a fusion protein, with the non-multifunctional protein portion of the protein serving either to facilitate purification or to enhance the immunogenicity of the fusion protein. For instance, the non-multifunctional protein portion comprises a protein for which there is a readily-available binding partner that is utilized for affinity purification of the fusion protein. The antigen includes an &#34;antigenic determinant,&#34; i.e., a minimum portion of amino acids sufficient to bind specifically with an anti-multifunctional protein antibody. 
     Antisera to multifunctional protein can be made, for example, by creating a multifunctional protein antigen by linking a portion of the cDNA for human multifunctional protein to a cDNA for glutathione s-transferase (&#34;GST&#34;) found on a commercial vector. The resulting vector expresses a fusion protein containing an antigenic segment of multifunctional protein and GST that is readily purified from the expressing bacteria using a glutathione affinity column. The purified antigenic fusion protein is used to immunize rabbits. The same approach is used to make antigens based on other segments of the multifunctional protein. Procedures for making antibodies and for identifying antigenic segments of proteins are well known. See, for instance, Harlow, Antibodies, Cold Spring Harbor Press, 1989. 
     6. Gene Therapy 
     The invention also encompasses the use of gene therapy approaches to insert a gene expressing a multifunctional protein or a polypeptide with multifunctional protein activity. For gene therapy, medical workers prefer to incorporate, into one or more cell types of an organism, a DNA vector capable of directing the synthesis of a polypeptide missing from the cell or useful to the cell or organism when expressed in greater amounts. The methods for introducing DNA to cause a cell to produce a new polypeptide or a greater amount of a polypeptide are called &#34;transfection&#34; methods. See, generally, Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Press, 1989. 
     For viral gene therapy vectors, dosages are generally from about 1 μg to about 1 mg of nucleic acid per kg of body mass. For non-infective gene therapy vectors, dosages are generally from about 1 μg to about 100 mg of nucleic acid per kg of body mass. 
     7. Routes of Administration 
     The multifunctional protein polypeptides and nucleic acid compositions of the invention can be administered orally, topically, rectally, vaginally, by instillation (for instance into the urinary tract or into fistulas), by pulmonary route by use of an aerosol, by application of drops to the eye, or systemically, such as parenterally, including, for example, intramuscularly, subcutaneously, intraperitoneally, intraarterially or intravenously. The multifunctional protein composition can be administered alone, or it can be combined with a pharmaceutically-acceptable carrier or excipient according to standard pharmaceutical practice. For the oral mode of administration, the multifunctional protein composition can be used in the form of tablets, capsules, lozenges, chewing gum, troches, powders, syrups, elixirs, aqueous solutions and suspensions, and the like. In the case of tablets, carriers that is used include lactose, sodium citrate and salts of phosphoric acid. Various disintegrants such as starch, and lubricating agents such as magnesium stearate and talc, are commonly used in tablets. For oral administration in capsule form, useful diluents are lactose and high molecular weight polyethylene glycols. If desired, certain sweetening and/or flavoring agents are added. For parenteral administration, sterile solutions of the multifunctional protein are usually prepared, and the pHs of the solutions are suitably adjusted and buffered. For intravenous use, the total concentration of solutes should be controlled to render the preparation isotonic. For ocular administration, ointments or droppable liquids may be delivered by ocular delivery systems known to the art such as applicators or eye droppers. Such compositions can include mucomimetics such as hyaluronic acid, chondroitin sulfate, hydroxypropyl methylcellulose or polyvinyl alcohol, preservatives such as sorbic acid, EDTA or benzylchronium chloride, and the usual quantities of diluents and/or carriers. For pulmonary administration, diluents and/or carriers will be selected to be appropriate to allow the formation of an aerosol. For topical administrations, the multifunctional protein is typically administered in aqueous form or in a hydrogel. A preferred hydrogel comprises an aqueous suspension of from about 1% (w/v) to about 10% of low molecular weight hydrolyzed starch. 
     Suppository forms of the multifunctional protein are useful for vaginal, urethral and rectal administrations. Such suppositories will generally be constructed of a mixture of substances that is solid at room temperature but melts at body temperature. The substances commonly used to create such vehicles include theobroma oil, glycerinated gelatin, hydrogenated vegetable oils, mixtures of polyethylene glycols of various molecular weighty and fatty acid esters of polyethylene glycol. See, Remington&#39;s Pharmaceutical Sciences, 16th Ed., Mack Publishing, Easton, Pa., 1980, pp. 1530-1533 for further discussion of suppository dosage forms. Analogous gels or cremes can be used for vaginal, urethral and rectal administrations. 
     Numerous administration vehicles will be apparent to those of ordinary skill in the art, including without limitation slow release formulations, liposomal formulations and polymeric matrices. 
     For topical treatments, a suitable dose of multifunctional protein per application ranges from about 0.1 μg/cm 2  to about 1 mg/cm 2 , preferably from about 1 μg/cm 2  (for example, using about 10 μg/ml) to about 1 mg/cm 2  (for example, using about 10 mg/ml), more preferably from about 5 μg/cm 2  (for example, using about 50 μg/ml) to about 100 μg/cm 2  (for example, using about 1 mg/ml), yet more preferably from about 10 μg/cm 2  to about 250 μg/cm 2 , still yet more preferably from about 10 μg/cm 2  (for example, using about 100 μg/ml) to about 50 μg/cm 2  (for example, about 500 μg/ml). For systemic treatments, dosages will generally be selected to maintain a serum level of multifunctional protein between about 0.1 μg/100 cc and about 5 μg/100 cc, preferably between about 0.5 μg/100 cc and about 2.0 μg/100 cc. In an alternative measure of preferred systemic administration amounts, preferably from about 0.1 mg/kg to about 10 mg/kg, more preferably about 1 mg/kg, will be administered (although toxicology in animal models suggests that in excess of 25 mg/kg is acceptable). For ocular treatments, a suitable dose of multifunctional protein per application ranges from about 0.01 mg per eye to about 5 mg per eye, preferably from about 0.1 mg per eye to about 2.0 mg per eye. For vaginal and urinary tract treatments, suitable flushing/instillation solutions of the multifunctional protein will generally have concentrations from about 1 μg/ml to about 15 mg/ml, preferably from about 100 μg/ml to about 3 mg/ml. For oral treatments, suitable mouthwash solutions will generally have concentration of multifunctional protein from about 1 mg/ml to about 15 mg/ml preferably from about 2 mg/ml to about 10 mg/ml. Lozenges will typically contain from about 100 μg to about 10 mg of multifunctional protein. Aerosols will generally be made from solutions having protein concentrations from about 0.1 mg/ml to about 15 mg/ml, preferably from about 1 mg/ml to about 10 mg/ml. Generally, from about 0.1 ml to about 2 ml of aerosol will be applied to the airways of the patient, preferably from about 0.5 ml to about 1.0 ml. For scar and keloid treatments, generally between about 0.1 mg and about 5 mg of multifunctional protein will be injected into each cm 2  of the lesion, preferably from about 0.5 mg to about 3 mg. For treating adhered connective tissue or joints, generally between about 0.5 mg and about 10 mg of multifunctional protein will be injected interstitially at the adhesion, preferably between about 1 mg and about 5 mg. For all treatments, the protein composition will generally be applied from about 1 to about 10 times per day, preferably from about 2 to about 5 times per day. These values, of course, will vary with a number of factors including the type and severity of the disease, and the age, weight and medical condition of the patient, as will be recognized by those of ordinary skill in the medical arts. It is believed that substantially higher doses can be used without substantial adverse effect. 
     For treating or preventing infection, the multifunctional protein can be administered systemically or in a manner adapted to target the affected tissue. For preventing cold or influenza transmission, the composition is preferably applied to the lungs or airways. For treating immune disorders, the composition may be applied systemically or in a manner adapted to target the affected tissue. For treating the primary and secondary infections of leprosy, the primary administration route will generally be the topical route. For treating scar or keloid tissue, generally the composition will be injected into the scar or keloid, except that for corneal scars the composition will generally be applied ocularly without injection. For cancer treatment, the composition will generally be administered systemically by a route or in a manner adopted to target the affected tissue. For treating atherosclerosis, the composition will generally be administered systemically, although the site of administration may be chosen to administer the highest dosages to the portion of the circulatory system most at risk. For asthma, the general route of administration will be pulmonary. For treating pseudomonas infections, the infection will typically be a lung infection and the administration route pulmonary. For reperfusion injury, the composition will generally be administered systemically, although the site of administration may be designed to administer the highest dosages to the portion of the body that suffered an ischemic event. For treating the painful symptoms of malaria, the administration mode will generally by systemic. 
     For wound healing, the multifunctional protein is preferably be applied more often than simply the time at which the wound is first dressed. Preferably, the multifunctional protein is applied at least about every time the wound dressing is changed. The multifunctional protein can also be applied at least about every other day, more preferably, every day. In one embodiment, the multifunctional protein is administered to a wound substantially free of necrotic tissue. The phrase &#34;substantially free of necrotic tissue&#34; shall mean sufficiently lacking in necrotic tissue so that an ordinarily-skilled pathologist would consider any residue of necrotic tissue to be irrelevant to determining a wound-healing prognosis. 
     For organ transplants, the organ to be transplanted will preferably be bathed in a solution of the multifunctional protein for between about 10 minutes and about 5 hours. The protein solution will preferably contain between about 0.01 mg/ml and about 25 mg/ml of the multifunctional protein, more preferably, between about 0.5 mg/ml and about 5 mg/ml. After transplantation, the multifunctional protein will preferably be administered systemically using the conditions described above. 
     For cleaning contact lenses in situ the solutions described above for ocular treatments are preferred; For ex vivo treatments, higher concentrations of protein will generally be used. Cleaning incubations of from about 5 to about 30 minutes at from about 20° C. to about 50° C. are also preferred. For ex vivo treatments, the higher end of the temperature range is preferred. 
     For leprosy, many of the associated infections will be appropriately treated with a topical application of the multifunctional protein. For CF or COPD, the multifunctional protein can be used to treat (a) the build up of viscous fluids in the lungs and (b) associated pulmonary infections. Preferably, treatments of CF and COPD patients include pulmonary treatments with an aerosol of the multifunctional protein, but can include other routes of administration including systemic administrations. 
     Particularly important among the diseases relevant to the transmission inhibitory embodiment of the invention are sexually-transmitted diseases, such as candida, gonorrhea, chlamydia, syphilis, trichomonas, chancroid, HIV, herpes or hepatitis infections. Among these, viral diseases are particularly preferred targets for transmission prevention; HIV is a still more preferred target. For this use, the body cavity involved in sexual activity is generally rinsed or flushed with a composition containing the multifunctional protein, or a creme, gel or suppository designed to localize the composition to the body cavity is used. The composition can be used soon before, in conjunction with, or soon after, sexual activity, although prior or concurrent use is preferred. 
     For herpes infections, the viral targets include HSV-1, which primarily manifests as oral herpes, HSV-2, which primarily manifests as genital herpes, and herpes zoster. 
     For autoimmune diseases or diseases with autoimmune components, treatment targets include without limitation rheumatoid arthritis, multiple sclerosis, primary biliary cirrhosis, active chronic hepatitis, ulcerative colitis, rheumatic arthritis, scleroderma, systemic lupus erythematosus, Hashimoto&#39;s thyroiditis, primary myxedema, thyroroxicosis, pernicious anemia, Addison&#39;s disease, premature onset of menopause, autoimmune male infertility, insulin-dependent diabetes, type B insulin resistance of acanthosis nigricans, alopic allergy, myasthenia gravis, Lambert-Eaton syndrome, Goodpasture&#39;s syndrome, pemphigus vulgaris, pemphigoid, phacogenic uveitis, sympathetic ophthalmia, autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura, Sjogren&#39;s syndrome, discoid lupus erythematosus, dermatomyositis and mixed connective tissue disease. 
     For adhesion disorders, the cells or viruses involved can include, without limitation, endothelial cells, lymphocytes, including T-cells, tumor cells, microbial cells, viruses, including HIV and herpes. Adhesion processes are believed to be involved in tissue invasion, for instance, by immune cells, microbes, and tumor cells. 
     For many of diseases for which the multifunctional protein of the invention is useful as a prophylactic treatment, including those not caused by microbes, a patient&#39;s medical history, lifestyle or genetic background will often indicate a predisposition to acquire the disease. This is true, for instance, of atherosclerosis. 
     Generally, the multifunctional protein will be administered in an effective amount. An effective amount is an amount effective to either (1) reduce the symptoms of the disease sought to be treated, (2) induce a pharmacological change relevant to treating the disease sought to be treated, (3) inhibit or prevent infection or re-infection by an infective agent, or (4) prevent the occurrence of a non-infectious disease (for instance a disease treatable by blocking a cell adhesion phenomenon). For cancer, an effective amount further includes an amount effective to: prevent or limit metastasis, for instance, to reduce the level of metastasis; reduce the size of a tumor; slow the growth of a tumor; and increase the life expectancy of the affected animal. For wound treatment, in one aspect, an effective amount includes an amount which, if regularly applied, prevents the occurrence of infection. In another aspect, for wound healing, an effective amount includes an amount effective to reduce the average time it takes for a wound to heal. 
     Humans are the preferred subjects for treatment. However, the multifunctional protein can be used in many veterinary contexts to treat animals, preferably to treat mammals, as will be recognized by those of ordinary skill in light of the present disclosure. 
     The present invention is further exemplified by the following non-limiting examples. 
     EXAMPLE 1 
     Cloning of PHIM Polypeptide 
     The PHIM polypeptide was purified and the polypeptide was partially sequenced, as described in U.S. patent application Ser. No. 08/600,273 (filed Feb. 8, 1996), deFaire et al., inventors, entitled &#34;Multifunctional Enzyme,&#34; relevant portions of which are hereby incorporated by reference. Degenerate oligonucleotide primers were constructed based on the partial amino acid sequence. The primers had the following sequences: CACGCCTACCCITGGCA (SEQ ID NO:17) and GTGTTGGACTCGATCCAGATC (SEQ ID NO:18). The primers were used to screen a krill cDNA library that was constructed in lambda zap, using the lambda zap cDNA synthesis kit (Stratagene, San Diego, Calif.). Three positive clones were identified through screening with a PCR fragment as a probe. The PCR fragment used as a probe was sequences 217 to 881 of SEQ ID NO:1, with the following changes: at 219, T to C; at 222, T to C; at 228, C to G; at 270, T to A; at 330, G to A; at 417, C to A; at 534, T to C; at 741, C to T; and at 825, C to G. The three positive clones were sequenced, the first clone resulting in SEQ ID NO:1, the second clone resulting in SEQ ID NO:2 and the third clone resulting in SEQ ID NO:7. These isoforms all lack the initiation codon methionine. 
     EXAMPLE 2 
     Expression of Recombinant Multifunctional Protein 
     A recombinant multifunctional protein was expressed in an E. coli as follows, using the BamHI and Xho I sites of a pET23c vector provided by Novagen (Abingdon, Oxford, U.K.). The pET23c vector includes a gene 10 tag for facilitating purification of the expressed recombinant protein. Further, the pET vector places the recombinant multifunctional protein under the control of bacteriophage T7 transcription and translation signals. Once established in a non-expression host, E. coli MC1061, the plasmid was then transferred to an expression host, E. coli BL21 (DE3) pLYS S having a chromosomal copy of the T7 polymerase gene under lacUV5 control. Expression was induced by the addition of 1 mM IPTG at an optical density of 0.5 at wavelength 600. The cells were harvested after 2 hours at an optical density of 1.0. The recombinant protein was insoluble in the lysate and after harvesting, it was washed and dissolved in 6 M urea. Refolding of the recombinant protein was carried out by 200-fold dilution using a buffer containing 100 mM tris HCl pH 9.5, 100 mM CaCl 2 , 0.3 mM oxidized glutathione and 3 mM reduced glutathione, followed by stirring overnight at 4° C.
