Abstract

The present invention provides novel polynucleotides encoding K+betaM3 polypeptides, fragments and homologues thereof. Also provided are vectors, host cells, antibodies, and recombinant and synthetic methods for producing said polypeptides. The invention further relates to diagnostic and therapeutic methods for applying these novel K+betaM3 polypeptides to the diagnosis, treatment, and/or prevention of various diseases and/or disorders related to these polypeptides. The invention further relates to screening methods for identifying agonists and antagonists of the polynucleotides and polypeptides of the present invention.

An isolated nucleic acid molecule comprising a polynucleotide having a nucleotide sequence at least 95.0% identical to a sequence selected from the group consisting of:

(a) a polynucleotide fragment of SEQ ID NO:
1 or a polynucleotide fragment of the eDNA sequence included in ATCC Deposit No:
XXXXX, which is hybridizable to SEQ ID NO 1;
(b) a polynucleotide encoding a polypeptide fragment of SEQ ID NO:
2 or a polypeptide fragment encoded by the cDNA sequence included in ATCC Deposit No:
XXXXX, which is hybridizable to SEQ ID NO:
1;
(c) a polynucleotide encoding a polypeptide domain of SEQ ID NO:
2 or a polypeptide domain encoded by the cDNA sequence included in ATCC Deposit No:
XXXXX, which is hybridizable to SEQ ID NO:
1;
(d) a polynucleotide encoding a polypeptide epitope of SEQ ID NO:
2 or a polypeptide epitope encoded by the cDNA sequence included in ATCC Deposit No:
XXXXX, which is hybridizable to SEQ ID NO:
1;
(e) a polynucleotide encoding a polypeptide of SEQ ID NO:
2 or the cDNA sequence included in ATCC Deposit No:
XXXXX, which is hybridizable to SEQ ID NO:
1, having potassium channel beta subunit activity;
(f) a polynucleotide which is a variant of SEQ ID NO:
1;
(g) a polynucleotide which is an allelic variant of SEQ ID NO:
1;
(h) an isolated polynucleotide comprising nucleotides 420 to 1097 of SEQ ID NO:
1, wherein said nucleotides encode a polypeptide corresponding to amino acids 2 to 227 of SEQ ID NO:
2 minus the start codon;
(i) an isolated polynucleotide comprising nucleotides 417 to 1097 of SEQ ID NO:
1, wherein said nucleotides encode a polypeptide corresponding to amino acids 1 to 227 of SEQ ID NO:
2 including the start codon;
(j) a polynucleotide which represents the complimentary sequence (antisense) of SEQ ID NO:
1;
and
(k) a polynucleotide capable of hybridizing under stringent conditions to any one of the polynucleotides specified in (a)-(j), wherein said polynucleotide does not hybridize under stringent conditions to a nucleic acid molecule having a nucleotide sequence of only A residues or of only T residues.
