GENE INFORMATION

Gene name

KCNMA1 (HGNC Symbol)

Synonyms

KCa1.1, mSLO1, SLO

Description

Potassium channel, calcium activated large conductance subfamily M alpha, member 1 (HGNC Symbol)

Entrez gene summary

MaxiK channels are large conductance, voltage and calcium-sensitive potassium channels which are fundamental to the control of smooth muscle tone and neuronal excitability. MaxiK channels can be formed by 2 subunits: the pore-forming alpha subunit, which is the product of this gene, and the modulatory beta subunit. Intracellular calcium regulates the physical association between the alpha and beta subunits. Alternatively spliced transcript variants encoding different isoforms have been identified.
