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, 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. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous inactivation of this gene leads to cerebellar ataxia, Purkinje cell dysfunction, uneven gait patterns, bladder hyperactivity, urinary incontinence, abnormal colonic K+ secretion, and hearing impairment. [provided by MGI curators]
