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. This gene is part of a tandem repeat on chromosome 15q15; the second copy of this gene is thought to be a pseudogene. Alternatively spliced transcript variants have been found for this gene.

PHENOTYPE: Homozygous null male mice are infertile due to a sperm motility defect. [provided by MGI curators]
