About KCNAB2

Cytogenetic location: 1p36.31 Genomic coordinates (GRCh38): 1:5,992,676-6,101,180 (from NCBI)

This gene has 48 transcripts (splice variants), 279 orthologues, 16 paralogues and is associated with 1 phenotype. Broad expression in brain (RPKM 17.0), bone marrow (RPKM 11.9) and 17 other tissues.

Summary

Voltage-gated potassium (Kv) channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Their diverse functions include regulating neurotransmitter release, heart rate, Insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. Four sequence-related Potassium Channel genes - shaker, shaw, shab, and shal - have been identified in Drosophila, and each has been shown to have human homolog(s). This gene encodes a member of the Potassium Channel, voltage-gated, shaker-related subfamily. This member is one of the beta subunits, which are auxiliary proteins associating with functional Kv-alpha subunits. This member alters functional properties of the KCNA4 gene product. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Dec 2010]
