FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Calcium ions play a primary role in the regulation of sperm motility. This gene belongs to a family of putative cation channels that are specific to spermatozoa and localize to the flagellum. The protein family features a single repeat with six membrane-spanning segments and a predicted calcium-selective pore region. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit sperm with markedly decreased motility that are unable to fertilize ova and lack a calcium ion influx response to cyclic-AMP. [provided by MGI curators]
