Catsper1 - cation channel, sperm associated 1

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. 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). [provided by Alliance of Genome Resources, Apr 2022]
