Homo sapiens

Also known as SLO; BKTM; SLO1; hSlo; IEG16; LIWAS; MaxiK; PNKD3; SAKCA; mSLO1; CADEDS; KCa1.1; SLO-ALPHA; bA205K10.1

Gene ID: 3778 | Gene type: protein coding

About KCNMA1

Cytogenetic location: 10q22.3 Genomic coordinates (GRCh38): 10:76,869,602-77,637,808 (from NCBI)

This gene has 94 transcripts (splice variants), 296 orthologues, 3 paralogues and is associated with 8 phenotypes. Broad expression in endometrium (RPKM 7.1), brain (RPKM 4.7) and 17 other tissues.

Summary

This gene encodes the alpha subunit of calcium-activated BK channel. The encoded protein is involved in several physiological processes including smooth muscle contraction, neurotransmitter release and neuronal excitability. Mutations in this gene are associated with a spectrum of neurological disorders including Paroxysmal Nonkinesigenic Dyskinesia 3, Idiopathic Generalized Epilepsy 16 and Liang-Wang syndrome.
