Automated description from the Alliance of Genome Resources (Release 3.2)
Exhibits voltage-gated calcium channel activity. Involved in several processes, including flagellated sperm motility; fusion of sperm to egg plasma membrane involved in single fertilization; and regulation of cilium beat frequency involved in ciliary motility. Localizes to CatSper complex. Is expressed in germ cell of testis; spermatid; spermatocyte; spermatozoon; and testis. Human ortholog(s) of this gene implicated in spermatogenic failure 7. Orthologous to human CATSPER1 (cation channel sperm associated 1).
