Automated description from the Alliance of Genome Resources (Release 5.2.2)
Enables voltage-gated calcium channel activity. Acts upstream of or within 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. Located in plasma membrane and sperm principal piece. Part of 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).
