Seπal No 08/655.847. filed May 31. 1996 The present invention relates to nucleic acid encoding the "GlyT-2" member of the family of human glycine transporters, to the isolated protein encoded by the nucleic acid, and to the field of drug discovery Synap c transmission is a complex form of intercellular communication that involves a considerable array of specialized structures in both the pre- and post-synaptic neuron High-affinity neurotransmitter transporters are one such component, located on the pre-synaptic terminal and surrounding glial cells ( anner and Schuldiner. CRC Critical Reviews in Biochemistry 22 1032, 1987) Transporters sequester neurotransmitter from the synapse, thereby regulating the concentration of neurotransmitter in the synapse, as well as its duration in the synapse, w hich together influence the magnitude of synapUc transmission By preventing the spread of transmitter to neighboring synapses, transporters maintain the fidelity of synaptic transmission Further, by sequesteπng released transmitter into the presynaptic terminal, transporters allow for transmitter reutihzation Neurotransmitter transport is dependent on extracellular sodium and the \ oltage difference across the membrane, under conditions of intense neuronal firing, as for example during a seizure, transporters can function in reverse, releasing neurotransmitter in a calcium-independent non-exocytotic manner (Attwell et al . Neuron 1 1 401 -407. 1993) Pharmacologic modulation of neurotransmitter transporters thus provides a means for modifying synaptic activity, which provides useful therapy for the treatment of neurological and psychiatric disturbances The amino acid glycine is a major neurotransm itter in the mammalian nervous system, functioning at both inhibitory and excitatory svnapses By the phrase "nervous system " both the central and peripheral portions of the nervous system are intended The distinct inhibitory and excitatory functions of glv cine are mediated by two different types of receptor, each of which is associated with a different class of glycine transporter The inhibitory actions of glycine are mediated by glvcine receptors that are sensitive to the convulsant alkaloid, strychnine, and are thus referred to as "strychnine- sensitive" Such receptors contain an intrinsic chloride channel that is opened upon binding of glycine to the receptor, by increasing chloride conductance, the threshold for firing of an action potential is increased Strychnine-sensitive glycine receptors are found predominantly in the spinal cord and bramstcm . and pharmacological agents that enhance the activation of such receptors will thus increase inhibitors neurotransmission in these regions Glycine functions in excitatory transmission by modulating the actions of glutamate, the major excitatory neurotransmitter in the central nervous system See Johnson and Ascher, Nature 325 529-531 . 1987. Fletcher et al . Glvcine Transmission Otterson and Storm-Mathisen, eds , 1990, pp 193-219 Specifically, glycine is an obligatory co-agonist at the class of glutamate receptor termed N-methyl-D-aspartatc (NMDA) receptor Activation of NMDA receptors on a neuron increases sodium and calcium conductance, which depolarizes the neuron, thereby increasing the likelihood that the neuron will fire an action potential NMDA receptors are widely distributed throughout the brain, with a particularly high density in the cerebral cortex and hippocampal formation Molecular cloning has revealed the existence in mammalian brains of two classes of glycine transporters, termed GlyT-1 and GlyT-2 GlyT-1 is found predominantly in the forebrain, and its distribution corresponds to that of glutamatergic pathways and NMDA receptors (Smith, et al , Neuron 8 927-935. 1992) The distribution of GlyT-2 differs, this transporter is found predominantly in the brain stem and spinal cord, and its distribution corresponds closely to that of strychnine-sensitive glycine receptors Liu et al , J Bwl Chem 268 22802-22808. 1993 , Jursky and Nelson. J Neurochem 64 1026-1033. 1995 These observations are consistent with the view that, by regulating the synaptic levels of glycine. GlyT-1 and GK T-2 preferentially influence the activity of NMDA receptors and strychnine-sensitive glycine receptors, respectively Sequence comparisons of GlyT- 1 and GlvT-2 have revealed that these glycine transporters are members of a broader family of sodium-dependent neurotransmitter transporters, including, for example, transporters specific for γ-amino-n- butyπc acid (GABA) and others Uhl, I rends in Neiiroscience 15 265-268. 1992 Clark and Amara, BwEssays 15 323-332. 1993 Overall, each of these transporters includes 12 putative transmembrane domains that predominantly contain hydrophobic ammo acids Comparing rat GlyT-1 to rat GlyT-2. using the Lipman-Pearson FAST A algorithm , reveals a 51 % ammo acid sequence identity and a 55% nucleic acid sequence identity Comparison of the sequence of human GlvT-1 with rat GlyT-2 reveals a 51% amino acid sequence identity and a 53-55% nucleic acid sequence identity, with the range of values for nucleic acid sequence identity resulting from the existence of three variant forms of GlyT-1 Compounds that inhibit or activate glycine transporters would be expected to alter receptor function, and provide therapeutic benefits in a vanety of disease states For example, inhibition of GlyT-2 can be used to diminish the activity of neurons having strychnine-sensitive glycine receptors via increasing synaptic levels of glycine. thus diminishing the transmission of pain-related (/ e , nociceptive) information in the spinal cord, which has been shown to be mediated by these receptors Yaksh, Pain 1 1 1 -123. 1989 Additionally, enhancing inhibitory glycinergic transmission through strychnine- sensitive glycine receptors in the spinal cord can be used to decrease muscle hyperactivity. which is useful in treating diseases or conditions associated with increased muscle contraction, such as spasticity. myoclonus (which relates to rapid muscle spasms). and epilepsy (Truong et al .

Molecular Cloning A Laboratory Manual. 2nd ed . Cold Spring Harbor Press. 1989 Hybridization conditions and probes can be adjusted in well -characterized ways to achieve selective hybridization of human-derived probes Nucleic acid molecules that will hybndize to a glycine transporter-encoding nucleic acid under stringent conditions can be identified functionally, using methods outlined above, or by using for example the hybridization rules reviewed in Sam brook ct al , Molecular Cloning A Laboratory Manual, 2nd ed , Cold Spπng Harbor Press. 1989 Without limitation, examples of the uses for hybridization probes include histochemical uses such as identifying tissues that express the human GlyT-2 transporter, measuring mRNA levels, for instance to identify a sample's tissue type or to identify cells that express abnormal levels of glycine transporter, and detecting polymorphisms in the glycine transporter gene RNA hybridization procedures are described in Maniatis et al Molecular Cloning, a Laboratory Manual (Cold Spring Harbor Press. 1989) PCR Primers Rules for designing polymerasc chain reaction ("PCR") primers are now established, as reviewed by PCR Protocols. Cold Spring Harbor Press. 1991 Degenerate primers, I e , preparations of primers that are heterogeneous at given sequence locations, can be designed to amplify nucleic acid sequences that are highly homologous to. but not identical to. a human GlyT-2 nucleic acid Strategies are now available that allow for only one of the primers to be required to specifically hybridize with a known sequence See. Froman et al . Proc Nail Acad S t USA 85 8998. 1988 and Loh el al Science 243 217. 1989 For example, appropriate nucleic acid primers can be ligated to the nucleic acid sought to be amplified to provide the hybridization partner for one of the primers In this way, only one of the primers need be based on the sequence of the nucleic acid sought to be amplified PCR methods of amplifying nucleic acid will utilize at least two primers One of these primers will be capable of hybridizing to a first strand of the nucleic acid to be amplified and of priming enzyme-driven nucleic acid synthesis in a first direction The other will be capable of hybridizing the reciprocal sequence of the first strand (if the sequence to be amplified is single stranded, this sequence will initially be hypothetical. but will be 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 pπmer Conditions for conducting such amplifications, particularly under preferred stringent hybridization conditions, arc well known See. for example, PCR Protocols, Cold Spring Harbor Press. 1991 Vectors A suitable expression vector is capable of fostering expression of the included GlyT-2 encoding DNA in a host cell, which can be eukaryotic, fungal, or prokaryotic Suitable expression vectors include pRc/CMV (Invitrogen, San Diego. CA), pRc/RSV (Invitrogen), pcDNA3 (Invitrogen). Zap Express Vector (Stratagene Cloning Systems, LaJolla. CA). pBk/CMV or pBk-RSV vectors (Stratagene). Bluescnpt II SK +/- Phagemid Vectors (Stratagene), LacSwitch (Stratagene), pMAM and pMAM neo (Clontech, Palo Alto, CA), pKSVlϋ (Pharmacia. Piscataway, NJ), pCRscπpt (Stratagene) and pCR2 1 (Invitrogen). among others Useful yeast expression systems include, for example, pYEUra3 (Clontech) Useful baculovirus vectors include several viral vectors from Invitrogen (San Diego. CA) such as pVL 1393. pVL 1392. pBluBac2. pBluBacHis A. B or C, and pbacPAC6 (from Clontech) Cells In one embodiment of the invention, the transporter is preferably expressed in a mammalian cell line, preferably a transformed cell line with an established cell ulture history In this embodiment, particularly preferred cell lines include COS-1. COS-7, LM(tk ~" ), HcLa. HEK293. CHO. Rat- 1 and NIH3T3 Other preferred cells include avian cells such as QT-6 cells Other cells that can be used include insect cells such as drosophila cells, fish cells, amphibian cells and reptilian cells In another embodiment, the transporter is expressed in a cell line that is more inexpensively maintained and grown than are mammalian cell lines, such as a bacterial cell line or a yeast cell line Isolated Glycine Transporter The invention also provides for the human GlyT-2 proteins encoded by any of the nucleic acids of the invention preferably in a puπty of at least about 80% with respect to proteins, preferably 90%, more preferably 95% The purities are achieved, for example, by applying protein purification methods, such as those described below, to a lysate of a recombinant cell according to the invention The human GIyT-2 variants of the above paragraphs can be used to create organisms or cells that produce human GlyT-2 activity Purification methods, including associated molecular biology methods, are described below Method of Producing Glycine Transporter One simplified method of isolating polypeptides synthesized by an organism under the direction of one of the nucleic acids of the invention is to recombinantly express a fusion protein wherein the fusion partner is facilely affinity purified For instance, the fusion partner can be glutathione S-transferase, which is encoded on commercial expression vectors (e g , vector pGEX4T3, available from Pharmacia, Piscataway, NJ) The fusion protein can then be purified on a glutathione affinity column (for instance, that available from Pharmacia. Piscataway. New Jersey) Additional fusion partners are available for example in various expression vectors sold bv Invitrogen (Carlsbad, CA) Of course, the recombinant polypeptides can be affinity puπfied without such a fusion partner using an appropπate antibody that binds to GlyT-2 Methods of producing such antibodies are available to those of ordinary skill in light of the ample description herein of GlyT-2 expression systems and known antibody production methods. See. for example. Ausubcl et al.. Short Protocols in Molecular Biology. John Wiley & Sons. New York. 1992 If fusion proteins are used, the fusion partner can be removed by partial proteolytic digestion approaches that preferentially attack unstructured regions such as the linkers between the fusion partner and GlyT-2 The linkers can be designed to lack structure, for instance using the rules for secondary structure forming potential developed, for instance, by Chou and Fasman. Biochemistry 13. 21 1 , 1974 and Chou and Fasman, Adv in Enzvmol 47. 45-147. 1978 The linker can also be designed to incorporate protease target amino acids, such as. arginine and lysinc residues, the ammo acids that define the sites cleaved by trypsin. or such as a target sequence for enterokinase. for example AspAspAspAspLys. which is cleaved after the lysine residue. To create the linkers, standard synthetic approaches for making oligonucleotides can be employed together with standard subcloning methodologies Other fusion partners besides GST can be used Procedures that utilize eukaryotic cells. particularly mammalian cells, are preferred since these cells will post-translationallv modify the protein to create molecules highly similar to or functionally identical to native proteins Additional purification techniques can be applied, 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, "salting out" precipitations), ion-exchange chromatography and affinity chromatography Because GlyT-2 is a membrane protein, which by analogy to related transporter proteins is believed to have twelve transmembrane sequences, isolation methods will often utilize detergents, generally non-ionic detergents, to maintain the appropriate secondary and tertiary structure of the protein. See. for example, Lopez- Corcuera et al.. J. Biol. Chem. 266- 24809-24814. 1991 For a description of methods for re-integrating a solubilized transporter into a membrane, see Lopez-Corcuera et al.. J Biol. Chem. 266: 24809-24814, 1991. The isolation of GlyT-2 can comprise isolating membranes from cells that have been transformed to express GlyT-2. Preferably, such cells express GlyT-2 in sufficient copy number such that the amount of GlyT-2 in a membrane fraction is at least about 10-fold higher than that found in comparable membranes from cells that naturally express Gl T-2, more preferably the amount is at least about 100-fold higher. Preferably, the protein is substantially pure, meaning a purity of at least 60% wt/ t with respect to other proteins For the purposes of this application GlyT-2 is "isolated" if it has been separated from other proteins or other macromolccules of the cell or tissue from which it is derived Preferably, the composition containing GlvT-2 is at least about 10-fold enriched, preferably at least about 100-fold, with respect to protein content, over the composition of the source cells Expression of GlyT-2 by RNA Insertion It w ill be recognized that human Glv T-2 can be expressed bv the simple method of inserting mRNA into a cell RNA for these uses can be prepared by sub- cloning the nucleic acid encoding a protein with Gl T-2 activity into a vector containing a promoter for high efficiency in vitro transcription, such as a SP6 or T7 RNA polym erase promoter RNA production from the vector can be conducted, for instance with the method described in Ausubel et al . Short Protocols in Molecular Biology. John Wiley & Sons. New York, 1992, pp 10-63 to 10-65 Insertion of RNA into Xenopus- denved oocytes is described, for instance, in Liu et al FEBS Letters 305 1 10-1 14 1992 and Bannon et al , J Neuroche 54 706-708. 1990 Alternatively, it will be recognized that human GlyT-2 can be expressed by the simple method of inserting mRNA into an in vitro translation system, which can be a membrane-containing translation system Expression of proteins in vitro is described, for instance, in Ausubel et al . Short Protocols in Molecular Bto/ogv John Wiley & Sons New York, 1992, pp 10-63 to 10-65 See, also, Guasteila et al Science 249 1303- 1306, 1990 (in vitro expression of a transporter) The use of subcellular membranous material to produce membrane proteins in vitro is described in Walter and Blobcl.

Cell 44 177, 1986 (for wheat germ translation system) Method of Characterizing or Identifying agent A method for the analysis of or screening for a bioactive agent for treatment of a disease or condition associated with a nervous system disorder or condition compπses cultuπng separately first and second cells, wherein the first and second cells are preferably of the same species, more preferably of the same strain thereof, and comprise an exogenous nucleic acid encoding a glycine transporter as described herein The nervous system disorders or conditions for which the agent can be used for treatment include, but are not limited to, (a) pain, (b) myoclonus. (c) muscle spasm, (d) muscle hyperactivity, (e) epilepsy or (f) spasticity such as that associated with stroke, head trauma, neuronal cell death, multiple sclerosis, spinal cord injury, dystonia, Huntington's disease or amyotrophic lateral sclerosis In this method, the first cell is contacted with the bioactive agent or a prospective agent, which is preferably a compound, such as a peptide or an organic compound in the presence of glycine which preferably incorporates a radioisotope. such as 3 H or 14 C The contacted first cell is then tested for enhancement or inhibition of glycine transport into the first cell as compared to glycine transport into the second cell that was not contacted with the compound (i e . the control cell) Such analysis or screening preferably includes activities of finding, learning, discovering. determining, identifying, or ascertaining Alternatively, the assay can utilize a composition comprising an isolated GlyT-2 transporter in place of cells Preferably , such preparation of isolated transporter will comprise membrane or hpid bilayer. preferably in vesicles, which vesicles have an inside and an outside across which transport can be measured Sec. for example Kanner. Biochemistry 17 1207-121 1. 1978 A bioactive agent is an enhancer of glycine transport uptake if at the end of the test the amount of intracellular. mtravesicle or otherwise transported glycine is greater in the agent-contacted composition than in the non -agent-contacted composition, conversely, a bioactive agent is an inhibitor of glycine transport if the amount of intracellular or mtravesicle glycine is greater in the non-agent-contacted composition as compared lo the other Preferably, the difference in glycine uptake between a tested first composition and a control second composition is at least about two-fold, more preferably, the difference is at least about five-fold, most preferably, the difference is at least about ten-fold or greater A bioactive agent that is an inhibitor or an enhancer with respect to the GlyT-2 transporter may have a neutral or opposite effect with another glycine transporter. such as one of the GlyT-1 transporters Preferred bioactive agents have specificity to enhance or inhibit the GlyT-2 transporter and have neutral or negligible effect on other glycine transporters Preferably, a bioactive agent has at least an order of magnitude greater potency, reflected in a concentration dependent parameter such as the IC 50 value. in inhibiting or activating glycine uptake mediated by the GlyT-2 transporter as compared to its effect on the second glycine transporter More preferred agents have greater potencies of at least about 100-fold for one of the glycine transporters as compared to the other The bioactive agent can be any compound, material, composition, mixture, or chemical, that can be presented to a glycine transporter in a form that allows for the agent to diffuse so as to contact the transporter Such bioactive agents include but are not limited to polypeptides preferably of two up to about 25 amino acids in length, more preferably from two to about ten, yet more preferably from two to about five amino acids in length Other suitable bioactive agents in the context of the present invention include small organic compounds, preferably of molecular weight between about 100 daltons and about 5.000 daltons. and arc composed of such functionalities as alkyl. arvl. alkene. alkyne. halo, cyano and other groups, including heteroatoms or not Such organic compounds can be carbohydrates, including simple sugars, amino or imino acids, nucleic acids, steroids, and others The chemicals tested as prospective agents can be prepared using combinatorial chemical processes known in the art or conventional means for chemical synthesis Preferably, bioactive agents arc useful as drugs for treatment of nervous system disorders or conditions Some compounds that inhibit GlyT- 1 or GlyT-2 mediated transport also bind to the glycine binding site on the strychnine-sensitive receptor, or to the glycine binding site on the NMDA receptor Such binding to the strychnine-sensitive receptor can be identified by a binding assay whereby, for example, radiolabeled strychnine is placed in contact with a preparation of strychnine-sensitive receptors, such as can be prepared from a membrane fraction from spinal cord or brain stem tissue A membrane fraction can be prepared using conventional means, including, for example, methods of homogenization and centπfugation Such binding to the NMDA receptor can be identified by a binding assay whereby, for example, radiolabeled glycine is placed in contact with a preparation of NMDA receptors, such as can be prepared from a membrane fraction from neuronal cells or brain tissue Gπmwood et al . Molec Pharmacol , 41 923-930, 1992 The NMDA receptors located in such membranes are treated using mild detergent, such as about 0 1% to about 0 5% saponin, to remove any endogenous glycine or glutamate The Iigand used in such a binding assay is radiolabeled with any detectable isotope, such as radioactive isotopes of carbon or hydrogen Specific binding of the radiolabeled Iigand is then determined by subtracting the radioactivity due to non-specific binding from that which is due to total (I e., specific and non-specific) binding of the radiolabeled Iigand The radioactivity due to non-specific binding is determined by measunng the amount of radiolabel associated with a strvchnine-sensitive or NMDA receptor-containing membrane fraction that has been contacted with both radiolabeled Iigand and a significant excess of non-radiolabeled Iigand, such as a 100-fold excess The radioactivity due to total binding of the radiolabeled Iigand is determined bv measuring the amount of radiolabel bound to the receptor preparation in the absence of non-radiolabeled Iigand For the NMDA receptor, one can also measure binding to the glycine site on the receptor using labeled analogs of amino acids, such as. for example. dichlorokynuremc acid or L-689.560 See. for example. Gnmwood et al . Molecular Pharmacol , 49 923-930. 1992 Functional ion-flux assays are used to measure the effect of compounds identified by the present invention in enhancing or inhibiting calcium flux (for NMDA receptor preparations) or chloride flux (for strychnine-sensitive receptor preparations) This test is performed on cell cultures that have membrane-bound NMDA receptors or strvchinine-sensitive receptors and glycine transporters Such cells include neuronal cells generally, including those of the brain stem and spinal cord, and cell lines derived therefrom, and any other cell that has been induced or transfected to express NMDA receptors or strychnine-sensitive receptors Calcium used in such a test is commonly the 4 Ca isotope, although other calcium measuring techniques can be used as well, such as calcium -associated fluorescence, which can be fluorescence associated with a calcium chelator. and the like Chloride used in such a test usually includes the isotope 6 C1 By whatever method the calcium or chloride is monitored, ion flux can be enhanced or inhibited as a result of the discrete addition of a bioactive agent of the present invention An advantage of this system is that it allows one to monitor the net effect on NMDA receptor or strychnine-sensitive receptor function of a compound that interacts with both the glycine site on a receptor and on a glycine transporter GlyT-2 inhibitors that are also strychnine-sensitive receptor agonists act in the above-described indications by increasing glycine concentrations at the strychnine- sensitive receptor-expressing synapses via inhibition of the glycine transporter, and via directly enhancing strychnine-sensitive receptor activity Glycine transporter inhibitors that are also strychnine-sensitive receptor antagonists can nonetheless retain activity in treating these indications, for example if the increase in glycine due to glycine transport inhibition prevails over the strychnine-sensitive receptor antagonism Where the strychnine-sensitive receptor antagonist activity prevails over the effect of increased extracellular glycine resulting from inhibition of the glycine transporter, these compounds are useful in treating conditions associated with decreased muscle activity such as myasthenia gravis As discussed above, the bioactive agents of the invention can have a number of phaπnacological actions The relative effectiveness of the compounds can be assessed in a number of ways, including the following 1 Comparing the activity mediated through GlyT- 1 and GlvT-2 transporters This testing identifies bioactive agents (a) that are more active against GlyT-1 transporters and thus more useful in treating or preventing schizophrenia, increasing cognition and enhancing memory or (b) that are more active against GlyT-2 transporters and thus more useful in treating or preventing epilepsy, pain or spasticity 2 Testing for strychnine-sensitive receptor or NMDA receptor binding This test establishes whether there is sufficient binding at this site to warrant further examination of the pharmacological effect of such binding 3 Testing the activity of the compounds in enhancing or diminishing ion fluxes in primary tissue culture, for example chloride ion fluxes mediated by strvchninc- sensitive receptors or calcium ion fluxes mediated by NMDA receptors A bioactive agent that increases ion flux either (a) has little or no antagonist activity at the strychnine-sensitive receptor and should not affect the potentiation of glycine activity through GlyT-2 transporter inhibition or (b). if marked increases are observed over results with comparative GlyT-2 inhibitors that have little direct interaction with strychnine- sensitive receptors, then the agent is a receptor agonist In some cases, the agent analysis method of the invention will be used to characterize whether a bioactive agent is useful in treating an indication in which NMDA receptors and GlyT-1 transporters are implicated In this case, generally, a lower measure of activity with respect to strychnine-sensitive receptors and GlyT-2 transporters is more desirable Antisense Therapies One aspect of the present invention is directed to the use of "antisense" nucleic acid to treat neurological indications such as those identified above The approach involves the use of an antisense molecule designed to bind mRNA coding for a GlyT-2, thereby stopping or inhibiting the translation of the mRNA. or to bind to the GlyT-2 gene to interfere with its transcription For discussion of the design of nucleotide sequences that bind genomic DNA to interfere with transcription, see Helene, Anti-Cancer Drug Design 6, 569, 1991 Once the sequence of the mRNA sought to be bound is known, an antisense molecule can be designed that binds the sense strand by the Watson-Cπck base-pairing rules, forming a duplex structure analogous to the DNA double helix Gene Regulation Biology of Antisense RNA and DNA, Eπkson and Ixzant, eds . Raven Press. New York. 1991. Helene. Anti-Cancer Drug Design. 6 569 ( 1 91 ). Crooke. Anti-Cancer Drug Design 6. 609. 1991 A serious bamer to fully exploiting antisense technology is the problem of efficiently introducing into cells a sufficient number of antisense molecules to effectively interfere with the translation of the targeted mRNA or the function of DNA One method that has been employed to overcome this problem is to covalently modify the 5' or the 3' end of the antisense polynucleic acid molecule with hydrophobic substituents These modified nucleic acids generally gam access lo the cells interior with greater efficiency See, for example. Boutoπn et al , FEBS Lett 23.1382-1390, 1989. Shea et al. Nucleic Acids Res 18, 3777-3783, 1990 Additionally, the phosphate backbone of the antisense molecules has been modified to remove or diminish negative charge (sec, for example Agπs et al , Biochemistry 25, 6268. 1986 Cazenave and Helene in Antisense Nucleic Acids and Proteins Fundamentals and Applications. Mol and Van dcr Krol. eds . p 47 et seq . Marcel Dekker. New York. 1991 ) or the puπne or pyπmidine bases have been modified (see, for example, Antisense Nucleic Acids and Proteins Fundamentals and Applications, Mol and Van der Krol, eds , p 47 et seq . Marcel Dekker, New York. 1991. Milhgan et al in Gene Therapy For Neoplasttc Diseases Huber and Laso. eds , p 228 et seq , New York Academy of Sciences. New York. 1994) Other methods to overcome the cell penetration barrier include incorporating antisense polynucleic acid sequences into expression vectors that can be inserted into the cell in low copy number, but which in the cell can direct the cellular machinery to synthesize more substantial amounts of antisense polynucleic molecules See. for example. Farhood et al . Ann N Y Acad Sci 716, 23, 1994 This strategy includes the use of recombinant viruses that have an expression site into which the antisense sequence has been incorporated See. e g , Bons-Lawrie and Temin, Ann N Y Acad Sci , 716 59 (1994) Others have tried to increase membrane permeability by neutralizing the negative charges on antisense molecules or other nucleic acid molecules with polycations See, e g Wu and Wu, Biochemistry, 27 887-892, 1988, Behr et al , Proc Nat/ Acad Sci U S A 86 6982-6986, 1989 For gene therapy such as antisense therapy, medical workers often try to incorporate, into one or more cell types of an organism, a DNA vector capable of directing the synthesis of a protein 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 protein or a greater amount of a protein are called "transfection" methods See. generally.

J.A.MA.. 270:2338 (1993), Dorudi et al., British J Surgery. 80.566 (1993) Other general methods of incorporating nucleic acids into cells include calcium phosphate precipitation of nucleic acid and incubation with the target cells (Graham and Van der Eb, Virology, 52.456. 1983), co-incubation of nucleic acid. DEAE-dextran and cells (Sompayrac and Danna. Proc Nail Acad Sci . 12 7575. 1981 ), electroporation of cells in the presence of nucleic acid (Potter et al.. Proc. Nail Acad Sci . 81.7161 -7165. 1984). incorporating nucleic acid into virus coats to create transfection vehicles (Gitman et al.. Proc. Nat/. Acad Sci U.S.A . 82:7309-7313. 1985) and incubating cells with nucleic acid incorporated into liposomes (Wang and Huang, Proc. Nail. Acad Sci., 84:7851 -7855, 1987) One approach to gene therapy is to incorporate the gene sought to be introduced into the cell into a virus, such as a herpes virus, adenovirus, parvovirus or a retrovirus. See. for instance, Akli et al.. Nature Genetics 3, 224. 1993 The nucleic acid compositions of the invention can be, for example. administered orally, topically, rectalfy. nasally, vaginally. by inhalation, for example by use of an aerosol, or parenterally, e.g. intramuscularly, subcutaneously, intraperitoneally. mtraventπcularly, or intravenously. The nucleic acid compositions can be administered alone, or they can be combined with a pharmaceutically-acceptable carrier or excipient according to standard pharmaceutical practice. For the oral mode of administration, the nucleic acid compositions can be used in the form of tablets, capsules, lozenges, troches, powders, syrups, elixirs, aqueous solutions and suspensions, and the like. In the case of tablets, carriers that can be used include lactose, sodium citrate and salts of phosphoric acid. Various disintegrants such as starch, and lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc, are commonly used in tablets. For oral administration in capsule form, useful diluents are lactose and high molecular weight polyethylene glycols. When aqueous suspensions are required for oral use. the nucleic acid compositions can be combined with emulsifying and suspending agents. If desired, certain sweetening and/or flavoring agents can be added. For parenteral administration. steπle solutions of the conjugate are usually prepared, and the pH 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 droppablc liquids may be delivered bv 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 poly(vιnyl 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 appropπate to allow ihe formation of an aerosol Generally, the nucleic acid compositions will be administered in an effective amount For pharmaceutical uses, an effectiv e amount is an amount effective to either (1 ) reduce the symptoms of the indication sought to be treated or (2) induce a pharmacological change relevant to treating or preventing the indication sought to be treated For viral gene therapy vectors, dosages will generally be from about 1 μg to about 1 mg of nucleic acid per kg of body mass For non-infective gene therapy vectors, dosages will generally be from about 1 μg to about 100 mg of nucleic acid per kg of body mass Antisense oligonucleotide dosages will generally be from about 1 μg to about 100 mg of nucleic acid per kg of body mass Autoimmune Disorders Autoimmune disorders whereby antibodies are produced against glycine transporters can be expected to be associated with disease states For example, for the GlyT-2 transporters, such disorders can be expected to be associated with decreased muscle activity, for instance decreased muscle activity that clinically presents much like myasthenia gravis, or to be associated with decreased pain perception Sec. for an example of a disease caused by autoantibodies to a molecule involved in neurotransmission (glutamic acid decarboxylase), Nathan et al , ./ Neurosci Res 40 134- 137, 1995. The presence of these antibodies can be measured by established immunological methods using protein sequences obtained from the nucleic acids descπbed herein or the related glycine transporters reported elsewhere See. for example. Kim et al., Mol Pharmacol . 45 608-617, 1994 and Liu et al , J Biol Chem 268 22802-22808, 1992. Such immunological methods are described, for example, in Ausubel et al., Short Protocols in Molecular Biology, John Wiley & Sons, New York, 1992 The following examples further illustrate the present invention, but of course, should not be construed as in any way limiting its scope Example I A - GlvT-2 Cloninc The cDNA encoding human GlyT-2 was generated by Reverse-Transcription PCR (RT-PCR) in two steps In the first step, a degenerate primer corresponding to the rat GlyT-2 nucleotide sequence from 2540 to 2521 (5'-GGRTCDATCATRTTYTTRTA) was used to prime cDNA synthesis from human spinal cord poly A mRNA (Clontech, Palo Alto, CA) The numbering recited herein for the rat sequence is according to the numbering reported in Liu et al.. J. Biol Chem. 268 22802-22808. 1992 The following primer pairs were then used in PCR reactions.
