Calcium ions play a primary role in the regulation ofsperm motility. This gene belongs to a family of putative cationchannels that are specific to spermatozoa and localize to theflagellum. The protein family features a single repeat with sixmembrane-spanning segments and a predicted calcium-selective poreregion. This gene is part of a tandem repeat on chromosome 15q15;the second copy of this gene is thought to be a pseudogene.Additional splice variants have been described but theirfull-length nature has not been determined.
