The four proteins in this family together form a Ca2+-permeant ion channel specific essential for the correct function of sperm cells.*{{cite web | url = http://www.iuphar-db.org/IC/FamilyIntroductionForward?familyId=13 | title = CatSper and Two-Pore Channels: Introduction | work = IUPHAR Database of Receptors and Ion Channels | publisher = International Union of Basic and Clinical Pharmacology | access-date = 2008-12-16 | archive-date = 2012-09-05 | archive-url = https://web.archive.org/web/20120905080216/http://www.iuphar-db.org/IC/FamilyIntroductionForward?familyId=13 | url-status = dead }}
Function
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.{{cite web | title = Entrez Gene: CatSper2 | url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=117155 }}
