Predicted to enable voltage-gated calcium channel activity. Predicted to be involved in calcium ion transmembrane transport. Predicted to act 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. Predicted to be located in plasma membrane. Predicted to be part of CatSper complex. 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]
