MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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 and the product of this gene, the modulatory beta subunit. Intracellular calcium regulates the physical association between the alpha and beta subunits. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous mutation of this gene results in increased blood pressure, and impaired motor coordination and cerebellar function. [provided by MGI curators]
