Gene: CATSPER1 (cation channel sperm associated 1) Homo sapiens
Symbol: CATSPER1
Name: cation channel sperm associated 1
Description: Predicted to have voltage-gated calcium channel activity. Predicted to be 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. Predicted to localize to CatSper complex. Implicated in spermatogenic failure 7.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: cation channel sperm-associated protein 1; cation channel, sperm associated 1; CATSPER; hCatSper; MGC33335; MGC33368; sperm ion channel; sperm-associated cation channel 1; SPGF7
