Novel esk potassium channel polypeptide and polynucleotide compositions

摘要

The present ivention provides a novel potassium channel subunit (ESK) and polynucleotides which identify and encode ESK. The invention also provides expression vectors and host cells comprising nucleic acid sequence encoding ESK. The invention also provides antibodies of ESK and methods of diagnosing and treating diseases associated with expression of ESK, and screening assays employing the polypeptide, nucleotide, and antibody compositions.
