## Abstract

Nucleic acids encoding each of three subunits, .alpha.1B, .alpha.2.delta., and .beta.3, of a calcium channel, are disclosed. Also disclosed are vectors containing the nucleic acids encoding the subunits; host cells containing the nucleic acids encoding the subunits; methods of isolating nucleic acids encoding related calcium channel subunits; the subunit proteins; fusion proteins comprising the subunit proteins; antibodies to the subunit proteins; assays to identify agents that modulate calcium channel activity, and agents identified thereby; methods of treating certain central nervous system disorders by altering calcium channel activity; and methods of diagnosing diseases associated with particular calcium channels, such as Lambert-Eaton syndrome.

## Background
Calcium channels are multi-subunit protein complexes that span the plasma membrane and are involved in the movement of calcium ions into the cell. Voltage-dependent calcium channels, the most common type of calcium channels, are classified as L-, T-, N-, or P-type channels, based on conductance levels, sensitivity to agonists and antagonists, and holding potential (K. Dunlap et al., Trends Neurosci. 18: 89-98 (1995)). Calcium channels contain two large subunits, .alpha.1 and .alpha.2, having molecular weights between about 130 and about 200 kDa, and one to three smaller subunits, such as .beta., and/or .gamma. subunits, each having a molecular weight that is usually less than about 60 kDa. At least one of the large subunits is glycosylated, and a smaller subunit may be glycosylated as well. Subunit .alpha.1 is approximately 200 to about 230 kDa, based on sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE). This subunit forms the pore through which calcium enters cells. Subunit .alpha.2 is approximately 160 to 190 kDa under non-reducing conditions on SDS-PAGE. The .gamma. subunit is about 52 to 65 kDa (SDS-PAGE); it is insensitive to reducing conditions. The .gamma. subunit, which is not observed in nervous tissue or in other certain preparations, is a glycoprotein of approximately 30 to 33 kDa (SDS-PAGE).

Investigation of particular calcium channel subtypes is rendered difficult by the presence of a mixture of different tissue-specific types of calcium channels in cells. Study of particular subtypes is essential, however, because of the importance of intracellular calcium levels in contributing to vital cellular processes including neurotransmitter release, muscle contraction, pacemaker activity, and secretion of hormones and other substances. A need remains for identifying and studying individual calcium channel subtypes.

The current invention pertains to the isolation and sequencing of nucleic acids encoding three subunits of human N-type calcium channel: an .alpha.1B subunit, an .alpha.2.delta. subunit, and a .beta.3 subunit. Previously unknown alterations are present in the sequence of nucleotides encoding each of the subunits. The nucleic acid encoding the .alpha.1B subunit has a change from G to A at position 194; a change from T to G at position 2559; a change from G to A at position 6470; and a deletion of nucleotides 4814-4819. The nucleic acid encoding the .alpha.2.delta. subunit has a change from A to C at position 329; a change from G to C at position 1191; a change from G to C at position 1219; a change from T to C at position 1596; a change from T to C at position 1980; a change from A to G at position 2090; and a change from A to G at position 3261. The nucleic acid encoding the .beta.3 subunit has a change from C to G at position 46; a TCC insertion at position 119; a change from A to T at position 203; a change from C to T at position 300; a change from C to G at position 303; a change from A to G at position 420; a change from C to T at position 438; a change from T to C at position 477; a change from T to G at position 486; a change from G to A at position 534; a change from A to C at position 552; a change from G to T at position 561; an ATG insertion at position 978; a change from T to A at position 1064; a change from CG to GC at positions 1283-1284; or a change from C to T at position 1308. Certain of these changes result in amino acid alterations in the encoded proteins, while others are synonymous changes.

Vectors containing the nucleic acids encoding the subunits described above have been prepared, as have host cells containing the nucleic acids. Methods of isolating nucleic acids encoding related calcium channel subunits, by employing hybridization of the nucleic acids of the invention to nucleic acid libraries, are now available by virtue of the discoveries described herein. Also available are the subunit proteins encoded by the nucleic acids, and also fusion proteins comprising the subunit proteins. Antibodies to the subunit proteins can also be generated. Assays to identify agents that modulate calcium channel activity are described, in which test cells are exposed to the agent to be tested and a calcium channel-selective ion; depolarizing the cell membrane of the test cell; detecting current flowing into the cell; and comparing the current to that of a control cell, wherein a difference in the current detected in the test cell, as compared with the current of the control cell, indicates that the agent modulates calcium channel activity. In addition, methods of diagnosing diseases associated with particular calcium channels, such as Lambert-Eaton syndrome, are described, using assays to detect the presence of calcium channel-specific antibodies in a sample from the individual suspected of having the disease.

The changes that are present in the subunits described herein may produce functional differences in the calcium channel formed by the three subunits, which will have an effect on the interaction between the calcium channels and agonists or antagonists of the channels. Furthermore, calcium channel subunits described herein are an advantageous combination, because the .beta.3 subunit is normally found associated with an .alpha.1B subunit in vivo; thus, this combination closely resembles the calcium channel in vivo.

The FIGURE is a graphic representation of average counts per minute (CPM) for omega-conotoxin GVIA-sensitive potassium-stimulated calcium uptake in cells transfected with the three human calcium channel subunits.

The current invention pertains to the isolation and identification of DNA encoding subunits of a particular calcium channel. As described in the Examples below, cDNA encoding an .alpha.1B subunit, an .alpha.2.delta. subunit, and a .beta.3 subunit of the human N-type calcium channel has been isolated. The cDNA clones have been inserted into expression vectors, and are stably expressed in transformed cell lines. The resulting transformed cells express each of the three mRNA encoding the individual subunits of the N-type channel. The transformed cells show omega-conotoxin GVIA binding activity, and omega-conotoxin GVIA toxin sensitive potassium-stimulated calcium uptake, indicating that the proteins expressed by the clones are capable of forming a functioning calcium channel.

As a result of this discovery, nucleic acids encoding the three subunits, as well as vectors containing the nucleic acids encoding one or more of the subunits, host cells containing the nucleic acids encoding one or more of the subunits, and methods of isolating nucleic acids encoding related calcium channel subunits are now available. The subunit proteins, fusion proteins comprising the subunit proteins, and antibodies to the subunit proteins, as well as assays to identify agents that modulate calcium channel activity, are also described. Agents that modulate calcium channel activity can be used to treat certain central nervous system disorders by altering calcium channel activity. In addition, methods of diagnosing diseases associated with particular calcium channels, such as Lambert-Eaton syndrome, are described.

A "nucleic acid encoding a calcium channel subunit", as used herein, is a sequence of nucleotides which encodes either an .alpha.1B subunit, an .alpha.2.delta. subunit, or a .beta.3 subunit of the N-type calcium channel. Nucleic acid encoding a calcium channel subunit can be either cDNA, DNA or mRNA. The nucleic acid encoding a calcium channel subunit is "isolated," indicating that it has been purified according to standard techniques known in the art (for example, such as by techniques described by Sambrook et al. (eds), in Molecular Cloning: A Laboratory Manual, (2nd ed.), Cold Spring Harbor Laboratory Press (1989)).

In one embodiment, nucleic acid encoding a calcium channel .alpha.1B subunit has the sequence of (SEQ ID NO. 1). In another embodiment, nucleic acid encoding a calcium channel .alpha.1B subunit is a nucleic acid encoding a functional equivalent of the subunit encoded by sequence of (SEQ ID NO. 1). A "functional equivalent" has the same function as the calcium channel subunit, but is encoded by a nucleic acid that may have minor variations in the sequence of nucleotides, in comparison to the nucleic acid encoding the subunit. A nucleic acid encoding a functional equivalent is referred to herein as an "equivalent" nucleic acid. Minor variations in equivalent nucleic acids include variations that result in no alteration of the encoded amino acid sequence (synonymous changes); variations that result in conservative amino acid substitutions in the encoded amino acid sequence; and/or minor deletions or insertions of nucleotides that do not alter the activity of the peptide. Such changes are readily known to the skilled artisan. For example, representative conservative amino acid changes include: alanine to glycine or serine; arginine to lysine; asparagine to glutamine or histidine; cysteine to serine; glutamine to asparagine; glutamate to aspartate; glycine to alanine or proline; histidine to asparagine or glutamine; isoleucine to leucine or valine; leucine to isoleucine or valine; lysine to arginine or glutamine; methionine to leucine tyrosine, or isoleucine; phenylalanine to methionine, leucine to tyrosine; serine to threonine; threonine to serine; tryptophan to tyrosine; tyrosine to tryptophan or phenylalanine; valine to isoleucine or leucine.

A functional equivalent of a subunit has an activity that is equivalent to the subunit. "Activity" refers to the ability of the peptide to form a functional calcium channel with other necessary subunits. A functional calcium channel is a calcium channel that is able to provide for and regulate entry of calcium channel-selective ions, including calcium, in response to appropriate stimuli, and/or is able to bind ligands having affinity for the calcium channel. The activity of a calcium channel may be assessed in vitro by standard methods, such as electrophysiological or other methods described below.

Nucleic acids encoding a functional equivalent of a calcium channel .alpha.1B subunit, include at least one of the following alterations, in comparison to the nucleic acid sequence in GenBank sequence data base, Accession number M94172 (see Williams, M. E. et al., Science 257: 389-395 (1992)): a change from G to A change at position 194; a change from T to G at position 2559; a change from G to A at position 6470; or a deletion of nucleotides 4814-4819. The nucleic acid having the sequence of SEQ ID NO. 1, as well as nucleic acids encoding a functional equivalent of the subunit encoded by the sequence of (SEQ ID No. 1), are collectively referred to herein as a nucleic acid encoding a calcium channel .alpha.1B subunit.

A nucleic acid encoding a calcium channel .alpha.2.delta. subunit has the sequence of SEQ ID NO. 3, or a sequence of nucleotides encoding a functional equivalent of the subunit encoded by the SEQ ID NO. 3. A nucleic acid encoding a functional equivalent of the subunit encoded by the sequence of 2 SEQ ID NO. 3 includes at least one of the following alterations, in comparison to the GenBank sequence data base, Accession number M76559 (Williams M. E. et al., Neuron 8: 71-84 (1992)): a change from A to C at position 329; a change from G to C at position 1191; a change from G to C at position 1219; a change from T to C at position 1596; a change from T to C at position 1980; a change from A to G at position 2090; or a change from A to G at position 3261.

A nucleic acid encoding a calcium channel .beta.3 subunit has the sequence of SEQ ID NO. 5, or the sequence of nucleotides encoding a functional equivalent of the subunit encoded by SEQ ID NO. 5. A sequence of nucleotides encoding a functional equivalent of the subunit encoded by SEQ ID NO. 5 includes at least one of the following alterations, in comparison to the GenBank sequence data base, Accession number L27584 (see Collin, T. et al., Eur. J. Biochem. 220(1): 257-262 (1994)): a change from C to G at position 46; a TCC insertion at position 119; a change from A to T at position 203; a change from C to T at position 300; a change from C to G at position 303; a change from A to G at position 420; a change from C to T at position 438; a change from T to C at position 477; a change from T to G at position 486; a change from G to A at position 534; a change from A to C at position 552; a change from G to T at position 561; an ATG insertion at position 978; a change from T to A at position 1064; a change from CG to GC at positions 1283-1284; or a change from C to T at position 1308.

The nucleic acids encoding calcium channel subunits of the invention can be used to isolate other nucleic acids encoding related subunits. For example, all or a portion of one of the nucleic acids encoding a calcium channel subunit can be used as a probe to isolate nucleic acids from a nucleic acid library by hybridization techniques. A "portion" of the nucleic acid indicates a part of the nucleic acid that contains one of the specific alterations described above. Stringency conditions should be tailored to eliminate hybridization of the probes to extraneous nucleic acid sequences (see Sambrook et al. (eds), Molecular Cloning: A Laboratory Manual, (2nd ed.), Cold Spring Harbor Laboratory Press (1989), particularly chapter 11.45). In a preferred embodiment, stringency conditions are selected such that the nucleic acid encoding a calcium channel subunit, or a portion of the nucleic acid, selectively hybridizes to a second nucleic acid (the target nucleic acid). "Selective hybridization" indicates that the hybridization is of sufficient specificity to allow the target nucleic acid to be identified or isolated from other nucleic acids. Generally, medium stringency conditions will allow selective hybridization. Nucleic acids that encode a calcium channel subunit, and are capable of selectively hybridizing, under medium or high stringency conditions, to all or a portion of a nucleic acid encoding a calcium channel subunit of the invention, or to all or a portion of a nucleic acid encoding a functional equivalent of a calcium channel subunit of the invention, are also encompassed by the invention.

Nucleic acids encoding a calcium channel .alpha.1B subunit, a calcium channel .alpha.2.delta. subunit, or a calcium channel .beta.3 subunit, as described above, can be inserted into a vector to facilitate expression. The vector is capable of expressing nucleic acids that are in operative linkage with endogenous or exogenous regulatory sequences; it may be a plasmid, a phage, a virus, or other vector. The vector can contain other elements, such as transcriptional promoter elements, enhancer elements, splicing signals, termination and polyadenylation signals, viral replicons, and/or bacterial plasmid sequences. Upon introduction of the vector into a host cell, the nucleic acid inserted into the vector is expressed. The vector can contain more than one nucleic acid encoding a calcium channel subunit of the invention. For example, a vector can contain nucleic acids encoding a calcium channel .alpha.1B subunit, as well as nucleic acids encoding a calcium channel .alpha.2.delta. subunit. If only one subunit is used, it is understood that other known sequences are present to encode a functional protein.

A vector containing the nucleic acids encoding a calcium channel subunit of the invention, as described above, can be transformed or transfected into an appropriate host cell for expression. Alternatively, a nucleic acid encoding a calcium channel subunit of the invention can be inserted directly into the host cell. The nucleic acids can be introduced into the cell in a manner such that they are integrated into the host cell genome; alternatively, they can be maintained episomally.

Representative host cells include Escherichia coli, HEK 293 cells, Chinese hamster ovary (CHO) cells, African green monkey cells, mouse L cells, amphibian oocytes, and CHODUX cells (Mitchell, P. J. et al., Mol. Cell Biol. 6(6)1926-35 (1986)). In a preferred embodiment, the host cell does not naturally contain nucleic acids encoding, or produce calcium channels comprising, .alpha.1B, .alpha.2.delta., or .beta.3 subunits, in order to facilitate distinguishing the nucleic acids and encoded subunits of the invention from other, native nucleic acids and subunits. In a more preferred embodiment, the host cell does not express or produce endogenous calcium channel subunits of the type, or in an amount, that substantially interferes with detection of the nucleic acids and encoded subunits of the invention.

A single .alpha.1 subunit is sufficient to form a calcium channel; therefore, at least the nucleic acid encoding the .alpha.1B subunit is introduced into the host cell. In a preferred embodiment, nucleic acids encoding each of the three subunits are introduced into the host cell such that the host cell expresses the subunits and includes one or more of them in membrane-spanning calcium channels. In a preferred embodiment, the host cell expresses functional calcium channels that are capable of controlling movement of calcium channel-selective ions and/or binding compounds. In a more preferred embodiment, the calcium channels are composed substantially or entirely of the three subunits encoded by the nucleic acids of the invention, in order to generate a calcium channel that is closer to the normal physiologic state of the channel in the mammalian central nervous system. A host cell which has been transformed or transfected as described above is also referred to herein as a transformed cell.

Host cells transformed or transfected with nucleic acids encoding one or more of the calcium channel subunits of the invention can be used for screening for compounds that modulate calcium channel activity. Because the host cells have a homogeneous population of calcium channels, they provide a means to identify agents that specifically modulate activity of the particular calcium channels. An agent that modulates (e.g., enhances or upregulates, or inhibits or downregulates) calcium channel activity is an agent that affects the ability of the calcium channel to pass calcium channel-selective ions, or affects other detectable calcium channel characteristics, such as current kinetics. The agent may affect the calcium channel directly or indirectly.

For example, transformed cells can be used in assays that identify agents that are agonists or antagonists of calcium channel activity. To identify agents that modulate calcium channel activity, a transformed cell (or a culture of transformed cells), used as a "test" cell, is maintained in a solution containing an agent to be tested for its ability to modulate calcium channel activity (the test agent) and a calcium channel selective ion. A "calcium channel selective ion" refers to an ion that is capable of flowing through, or being blocked from flowing through, a calcium channel which spans a cellular membrane under conditions which would permit or block the flow of calcium ions. Ba.sup.2+  is an example of a calcium channel selective ion. The cell membrane of the test cell is then depolarized, and current flowing into the test cell is detected. If the current that is detected is different from the current produced by depolarizing the same cell or a control cell in the presence of the same calcium channel selective ion, but in the absence of the compound, then the agent modulates calcium channel activity. In a preferred embodiment, the test cell is maintained at a holding potential which substantially inactivates calcium channels prior to the depolarization step. If the current is higher in the presence of the agent than in the absence of the agent, then the agent is an agent that enhances calcium channel activity (a calcium channel agonist). If the current is lower in the presence of the agent than in the absence of the agent, then the agent is an agent that inhibits calcium channel activity (a calcium channel antagonist).

One "control" cell which can be used as described above, is a cell that is maintained in substantially the same manner as the test cell, with the exception that the control cell is not exposed to the agent to be tested. An alternative "control" cell is a cell which is identical to the test cell, except that it does not express functional calcium channels.

Agents identified by these methods can be used to modulate activity of calcium channels in vivo. The in vitro assays described above should accurately predict relative efficacy of an agent as an agonist or an antagonist of calcium channels, since the calcium channel subunits described herein are subtype- and tissue-specific. Specific disease targets include central nervous system disorders, including stroke, cerebral ischemia, epilepsy, chronic pain, head trauma, and other central nervous system diseases or conditions in which too much or too little neurotransmitter is released. The agent is administered by an appropriate route, such as orally, subcutaneously, transdermally, intravenously, intramuscularly, intraperitoneally, topically, rectally, vaginally, nasally, or via an implanted reservoir. The agent can be administered in dosage formulations containing conventional, non-toxic, physiologically-acceptable carriers, adjuvants, and/or vehicles. The formulation in which the agent is administered will depend at least in part on the route by which it is administered. The agent is administered in an effective amount, which is that amount necessary to alleviate, reduce, eliminate, or prevent the symptoms associated with the disease, disorder or condition to be treated. More than one agent can be administered; if more than agent is used, the effective amount is that amount of the combination of agents that is necessary to alleviate, reduce, eliminate or prevent the symptoms associated with disease, disorder or condition. The effective amount will be determined on an individual basis, and will be based in part, on consideration of the particular agent, the individual's size and gender, the severity of the symptoms to be treated, the result sought, and the disease, disorder or condition to be treated. The effective amount can be administered in a series of doses separated by appropriate intervals, such as hours, days, or weeks. Alternatively, the effective amount can be administered as a sustained release dose, such as by a controlled-release dosage formulation.

Purified proteins encoded by a nucleic acid encoding a calcium channel .alpha.1B subunit, a calcium channel .alpha.2.delta. subunit, or a calcium channel .beta.3 subunit, as described above, are also described. The proteins (also referred to herein as calcium channel subunits of the invention) can be isolated from a host cell transfected or transformed with the nucleic acid encoding the subunit. Representative proteins include a calcium channel .alpha.1B subunit having the amino acid sequence 7 SEQ ID NO. 2; a calcium channel .alpha.2.delta. subunit having the amino acid sequence 7 SEQ ID NO. 4; or a calcium channel .beta.3 subunit having the amino acid sequence of 7 SEQ ID NO. 6.

Fusion proteins comprising the calcium channel .alpha.1B subunit, a calcium channel .alpha.2.delta. subunit, or a calcium channel .beta.3 subunit can also be generated using standard techniques. For example, a fusion nucleic acid can be generated by splicing, or attaching the nucleic acid encoding the calcium channel subunit to a nucleic acid encoding another protein or peptide (the fusion partner or protein), or by inserting the nucleic acid encoding the calcium channel subunit and the fusion protein into a common vector; the fusion nucleic acid can then be transformed, transfected, or inserted into a host cell for transcription and translation.

Antibodies (or immunoglobulins) to the calcium channel subunits of the invention can be generated. The term "antibody", as used herein, encompasses both polyclonal and monoclonal antibodies, as well as mixtures of more than one antibody reactive with a calcium channel subunit of the invention (e.g., a cocktail of different types of monoclonal antibodies reactive with the mutant protein or protein fragment). The term antibody is further intended to encompass whole antibodies and/or biologically functional fragments thereof, chimeric antibodies comprising portions from more than one species, humanized antibodies, human-like antibodies, and bifunctional antibodies. Biologically functional antibody fragments which can be used are those fragments sufficient for binding of the antibody fragment to the calcium channel subunit of interest. Once the antibodies are raised, they are assessed for the ability to bind to the calcium channel subunit of interest. Conventional methods can be used to perform this assessment. Antibodies can also be raised to calcium channels formed by the combination of the calcium channel .alpha.1B subunit, the calcium channel .alpha.2.delta. subunit, and the calcium channel .beta.3 subunit described herein.

The chimeric antibodies can comprise portions derived from two different species (e.g., a constant region from one species and variable or binding regions from another species). The portions derived from two different species can be joined together chemically by conventional techniques or can be prepared as single contiguous proteins using genetic engineering techniques. DNA encoding the proteins of both the light chain and heavy chain portions of the chimeric antibody can be expressed as contiguous proteins.

Monoclonal antibodies (mAb) reactive with a calcium channel subunit of the invention, or a calcium channel formed by the subunits, can be produced using somatic cell hybridization techniques (Kohler and Milstein, Nature 256: 495-497 (1975)) or other techniques. In a typical hybridization procedure, purified calcium channel subunit, or calcium channels, can be used as the immunogen. An animal is immunized with the immunogen to obtain antibody-producing spleen cells. The species of animal immunized will vary depending on the specificity of mAb desired. The antibody producing cell is fused with an immortalizing cell (e.g., a myeloma cell) to create a hybridoma capable of secreting antibodies. The unfused residual antibody-producing cells and immortalizing cells are eliminated. Hybridomas producing desired antibodies are selected using conventional techniques and the selected hybridomas are cloned and cultured.

Polyclonal antibodies can be prepared by immunizing an animal in a similar fashion as described above for the production of monoclonal antibodies. The animal is maintained under conditions whereby antibodies reactive with the calcium channel subunit of interest, or the calcium channel, are produced. Blood is collected from the animal upon reaching a desired titer of antibodies. The serum containing the polyclonal antibodies (antisera) is separated from the other blood components. The polyclonal antibody-containing serum can optionally be further separated into fractions of particular types of antibodies (e.g., IgG, IgM).

Antibodies that are specific for the calcium channel subunits of the invention, or for the calcium channel formed by the three subunits of the invention, can be used for immunohistochemistry to monitor distribution and expression density of the various subunits, or of the calcium channels themselves, in different tissues, including in normal and in diseased tissue. The antibodies can also be used as a therapeutic agent, in order to modulate calcium channel activity, as described in detail above.

Antibodies that are specific for the calcium channel subunits of the invention, or for the calcium channel formed by the three subunits of the invention, can also be used to facilitate diagnosis of Lambert-Eaton Syndrome (LES). LES autoimmune disease is characterized by insufficient release of acetylcholine from motor nerve terminals which normally are responsive to nerve impulses. IgG from LES patients block individual voltage-dependent calcium channels and thus inhibit calcium channel activity (Kim and Neher, Science 239: 405-8 (1988)). To diagnose LES, a test sample of blood or other bodily fluid is obtained from an individual suspected of having or carrying the disease. The test sample is contacted with a calcium channel subunit of the invention, or a calcium channel formed by the three subunits of the invention, under conditions which would allow any antibody which is specific for the calcium channel subunit or the calcium channel, and which may be present in the test sample, to bind. Binding of antibody to the calcium channel subunit of the invention, or the calcium channel formed by the subunits of the invention, if such binding exists, is then detected. The presence of binding indicates that the individual has antibodies to the calcium channel, and thus, is afflicted with LES.

The invention is further illustrated by the following Examples. Channel

Sequences referred to herein are described in comparison to the sequence encoding an .alpha.1B subchannel, described in the GenBank sequence data base, Accession number M94172 (see William, M. E. et al., Science 257: 389-395 (1992)).

A. Isolation of Primary Clones

Three primary clones, each containing a portion of the .alpha..sub.1B subunit, were obtained by hybridization under low stringency conditions with human cerebellum library at 50.degree. C. in 6.times. sodium chloride, sodium citrate (SCC) overnight. Hybridized nucleic acids were washed using standard techniques (see Sambrook et al. (eds), Molecular Cloning: A Laboratory Manual, (2nd ed.), Cold Spring Harbor Laboratory Press (1989)).

First, clone pN, which spans sequences 54-1405, was cloned into the SmaI site of pSK-(Bluescript). The SacI site of the polylinker is at the 5' end. The SmaI site was destroyed. pN has a single nucleotide change (G to A at position 194), which alters the amino acid at the corresponding position in the protein from gly to ser.

The second clone, pM, spans sequences 978-4562. EcoRI/blunt fragment was inserted into EcoRI/SmaI sites of pSK-. The KpnI site of the polylinker was at the 5' end. The SmaI site was destroyed. pM has a single nucleotide change (T to G at position 2559), which results in an alteration of the amino acid at the corresponding position from leu to arg.

Clone pC, which spans sequences 4105-7322, was also isolated. An EcoRI/XbaI fragment was cloned into EcoRI/XbaI restricted pNK-CMV vector. The SacI site of the polylinker is at the 5' end. Clone pC has two changes: a single nucleotide change at position 6470 (G to A), resulting in an alteration of the corresponding amino acid from gly to ser; and a six base pair deletion at nucleic acid positions 4814-4819, resulting in a deletion of the two corresponding amino acids (glu and thr).

B. Generation of pSK-H.alpha.1

In order to generate a clone containing the entire .alpha.1B cDNA, combination vectors were made. First, pMC was created. To allow cleavage by MamI, both pM and pC were transformed into SCS110 cells (Stratagene; dam-, dcm-), and the unmethylated DNA was isolated. pC was digested with XbaI and MamI, and the 2930 bp fragment was isolated. pM was also digested with MamI and XbaI, and the 6.4 kb vector+ insert band was isolated. These two fragments were ligated together to create pMC. The fusion point is the MamI site at position 4395.

pNMC, a fusion of pN and pMC, was then generated. pN was restricted with KpnI and XbaI, and the 1.4 kb insert was isolated. pMC was restricted with XbaI and partially restricted with KpnI. The 6012 XbaI/KpnI fragment was isolated. These two fragments were ligated together, and the ligation reaction was then cut with XbaI. The resulting fragments were then ligated to a pSK- vector restricted with XbaI. The resulting plasmid contains the entire coding sequence of .alpha.1, with 91 bp 5' UT, and 157 bp 3' UT (pos 54-7322). the fusion point is the KpnI site at position 1310. The KpnI site of the pSK- polylinker is at the 5' end. This pNMC vector is referred to as pSK-H.alpha.1.

C. Expression Clones

Two expression clones were generated. The first, pNK-H.alpha.1, was constructed by isolating the XbaI insert of pSK-H.alpha.1; this XbaI insert was inserted into the XbaI site of pNK-CMV. The polylinker SacI site is at the 5' end.

A second expression clone, pNK-H.alpha.1-Koz, was also generated. A 540 primer containing an optimized Kozak sequence (CCACCATGG) (SEQ ID No. 7), an EcoRI site, and surrounding bases was synthesized. A 3' primer spanning the BglII site at position 1463 was also synthesized. These primers were used to PCR the .alpha.1 5' end from pNK-H.alpha.1. This product was cut with EcoRI and BglII, and cloned into a likewise restricted pNK-H.alpha.1 plasmid. The resulting truncated plasmid contains the Kozak sequence and has been shown to express at least as well as the parent plasmid in transient transfection studies.

The H.alpha.1 gene thus includes several changes from the previously known sequence presented in the GenBank sequence data base, Accession number M94172. A single nucleotide change (G to A at position 194), alters the amino acid at the corresponding position in the protein from gly to ser; a single nucleotide change (T to G at position 2559), results in an alteration of the amino acid at the corresponding position from leu to arg. Also, a single nucleotide change at position 6470 (G to A), results in an alteration of the corresponding amino acid from gly to ser; and a six base pair deletion at nucleic acid positions 4814-4819, results in a deletion of the two corresponding amino acids (glu and thr). These alterations are summarized in Table I. ______________________________________ .alpha.1B Alterations Nucleotide Position  Change         Amino Acid Change ______________________________________ 194      G to A         Gly to Ser 2559      T to G         Leu to Arg 6470      G to A         Gly to Ser 4814-4819 Deletion 6 bp  Deletion Glu and Thr ______________________________________ N-Type Channel

Sequences referred to herein are described in comparison to the sequence encoding an .alpha.2.delta. subchannel, described in the GenBank sequence data base, Accssion number M76556 (Williams, M. E. et al., Neuron 8: 71-84 (1992)).

A. Isolation of Primary Clones and Generation of clone pNK-H.alpha.2

The clone pNK-H.alpha.2, was constructed as a fusion of two PCR clones. The template was human cerebellum QuickClone (Clonetech) cDNA, and the two PCR clones included sequences from 16-1409 (p2110) and from 1379-3313 (p2223). They were isolated as T/A clones in PCRII (Invitrogen) with the polylinker NotI site at the 5' end of each clone. p2110 was restricted with EcoRI and NsiI, and p2223 was restricted with NsiI and KpnI. The gel-purified inserts were fused at the NsiI site (Pos. 1394) and cloned into an EcoRI/KpnI restricted pNK-CMV vector. The SacI site is at the 5' end.

This clone, pNK-H.alpha.2, contained certain alterations from a previously identified .alpha.2 sequence described in the GenBank sequence data base Accession number M76559 EMBL file. These alterations are summarized in Table II. ______________________________________ Alterations in H.alpha.2.delta.

B. Expression Clones

Two expression clones were generated. First, pNK-H.alpha.2 was cut with KpnI and blunt ended. EcoRI linkers were attached. The reaction was treated with EcoRI, and the 3.3 kb EcoRI insert was isolated. This EcoRI insert was ligated into two different vectors, pED, and pBabe-CMV, which had been restricted with EcoRI. The correct orientations were selected. The resultant expression clones are referred to herein as pBabe-H.alpha.2 and pED-H.alpha.2. Channel

Sequences referred to herein are described in comparison to the sequence encoding an .beta.3 subchannel, described in the GenBank sequence data base, Accession number L27584 (see Collin, T. et al., Eur. J. Biochem. 220(1): 257-262 (1994)).

A. Isolation of Primary Clones and Generation of Clone pNK-H.beta.3

A blunt ended PCR product spanning sequences 21-1490 was cloned into the EcoRI site of pSK-. The template was human cerebellum QuickClone (Clonetech) cDNA, generating pSK-H.beta.3. The EcoRI/KpnI insert of pSK-H.beta.3 was isolated and subsequently subcloned into the EcoRI/KpnI sites of pNK-CMV. The SacI site of the polylinker is at the 5' end. This clone, pNK-H.beta.3, contained certain alterations from a previously identified .beta.3 sequence described in the HUMCALBA Genbank file. These alterations are summarized in Table III. ______________________________________ Alterations in H.beta.3 Nucleotide    Amino Acid Position     Change        Change ______________________________________ 46          C to G        Leu to Val 119          TCC insertion Ser insertion 203          A to T        Glu to Val 300          C to T        no change 303          C to G        no change 420          A to G        no change 438          C to T        no change 477          T to C        no change 486          T to G        no change 534          G to A        no change 552          A to C        no change 561          G to T        no change 978          ATG insertion Met insertion 1064         T to A        Leu to His 1283-4       CG to GC      Thr to Ser 1308         C to T        no change ______________________________________

CHODUX cells (Mitchell, P. J. et al., Mol. Cell Bio. 6(6): 1926-35 (1986), Genbank M13476, M13477) were seeded on 100 mm dishes with 1 to 2.times.10.sup.6 cells, at 24 hours before transfection. Cells were transformed with each of the following three expression clones: pNK-H.alpha.1, pNK-H.alpha.2, and pNK-H.beta.3, using CaPO.sub.4 transfection kit (Stratagene Mammalian Transfection Kit) according to the manufacturer's instructions. Cells were then washed using a single PBS wash, being careful not to dislodge cells. Thirty to 35 .mu.g DNA was used per plate, in an approximately 2:1:1 subunit ratio (20 .mu.g .alpha.1B, 7.5 .mu.g .alpha.2.delta., 5 .mu.g .beta.3). Transfection was allowed to proceed for approximately 16 hours overnight.

Saturating binding experiments were performed on the cells using a protocol as described by Harpold et al. (Science 257: 389-395 (1992)). Briefly, reaction tubes containing .sup.125 I-omega-conotoxin GVIA (NEN) were prepared. The .sup.125 I-omega-conotoxin GVIA is packaged in vials of 10 .mu.Ci at a specific activity of 2200 Ci/mmol. The vial is resuspended in 450 .mu.l water, to obtain 10 nM. For a 200 pM (saturating) final concentration, 10.mu.l/0.5 ml reaction was used. Cells were washed 1.times. with PBS and resuspended with 1-2 ml binding buffer and BSA per plate by pipetting. Approximately 500,000 cells (50-100 .mu.l) per 0.5 ml reaction were used to initiate binding reaction. The reaction was allowed to proceed for 30-60 minutes at 37.degree. C. Subsequently, 1 ml cold wash buffer+BSA was added, and cells were pelleted by 5 minutes at 2.8 krpm at 4.degree. C. (Sorvall RT6000). Cells were washed 1.times. with 2 ml cold wash buffer+BSA and resuspended by gently vortexing; subsequently, they were repelleted. After aspiration of liquid, scintillation counting was performed.

Results of the experiments demonstrated specific omega-conotoxin GVIA binding to whole cells. Specific binding indicates that the expression clones were expressed, and that the expressed subunits formed calcium channels. Potassium-Stimulated Calcium Uptake

The uptake of .sup.45 Ca into cells was performed by an adaptation of the method of Tan, K. and A. H. Tashjian (J. Biol. Chem. 259: 418-426 (1984). The principle of the method involves activating ion permeation through synaptosomal calcium channels by high potassium-induced depolarization of the synaptosomal preparation. The uptake of .sup.45 Ca measured by this procedure is mediated by N-type calcium channels, and is sensitive to dihydropyridine, phenylalkylamine, and benzothiazipine Ca antagonists at therapeutically relevant concentrations (Tan and Tashjian, ibid.)

Cells were transfected with the three human calcium channel subunits described herein. Transfected cells were suspended in 15 ml growth medium (Ham's F-10 medium plus 15% heat-inactivated horse serum and 2.5% heat-inactivated fetal bovine serum). The cells were centrifuged, resuspended, and then added to T-75 flasks containing 12-15 mls growth medium, and incubated at 37.degree. C. for approximately one week. The cells were then removed from the flask after dissociation from the walls of the flask by treatment for 5 minutes at 37.degree. C. with 10 .mu.M EDTA in phosphate buffered saline. The buffer was decanted, and the cells were resuspended in approximately 200 ml of growth medium. The cells were then aliquoted 200 .mu.g/well) into each well of several 96-well plates, and grown under the aforementioned conditions for 3-4 weeks, with replacement of growth medium occurring twice per week. Cells were fed growth medium 24 hours before they are employed for .sup.45 Ca uptake determinations.

At the time of the assay, media was aspirated from each 96-well plate using a manifold designed to allow 50 .mu.L of liquid to remain in each well. Each plate was washed and aspirated twice with a low K+ buffer solution "LKHBBS" (in mM: 5 KCl, 145 NaCl, 10 Hepes, 1 MgCl.sub.2, 0.5 CaCl.sub.2, 10 glucose, pH 7.4), 200 .mu.l/well. Each plate was incubated for 10 minutes at 37.degree. C., and aspirated as above. To each well of each plate, 50 .mu.l of LKHBBS containing the agent in twice the final concentration was added. The agents added are set forth in Table IV. ______________________________________ Agents Added to Transfected Cells, Demonstrating omega-Conotoxin GVIA-Sensitive Potassium- Stimulated Calcium Uptake Sample   Cell Type      Agent Added ______________________________________ 1        HEK293         Control (no agent) 2        HEK293         75 mM KCl 3        T9             Control (no agent) 4        T9             74 mM KCl 5        T9             SNX-111 (10 .mu.M) 6        T9             SNX-111 (10 .mu.M) plus KCl (negative control) 7        T9             gadolinium (10 .mu.M) 8        T9             gadolinium (10 .mu.M) plus KCl (negative control) ______________________________________

The plates were incubated for 10 minutes at room temperature. To each well of each plate, 50 .mu.l of either of two solutions were added: (a) LKHBBS containing 1 .mu.Ci of carrier-free .sup.45 Ca, or (b) HKHBBS (a high K+ buffer containing 150 mM KCl and no NaCl, but otherwise identical to LKHBBS).

Each plate was then incubated for 5 minutes at room temperature, aspirated as above, and quenched with 200 .mu.l/well of Quench Buffer (Ca-free LKHBBS containing 10 mM Tris-EGTA). Each plate was aspirated and rinsed with Quench Buffer a second time, then carefully aspirated to dryness. To each well of each plate 100 .mu.l of High Safe II scintillation fluid (MicroScint (Packard)) was added. The plates were sealed, shaken, and subjected to scintillation spectrophotometry on a Microbeta 96-well Scintillation Counter (Wallac, Gaithersburg, Md., USA). Average counts per minute (CPM) are plotted in the FIGURE (numbering of data points corresponds to the numbering of agents in Table IV). Results indicated that omega-conotoxin GVIA-sensitive potassium-stimulated calcium uptake occurred in the transfected cells, and was inhibited by the agents known to inhibit L-type calcium channels, thereby demonstrating that the three subunits formed a functioning calcium channel.
