Catsper1 Gene Summary [Rat]

Predicted to enable voltage-gated calcium channel activity. Predicted to be involved in several processes, including calcium ion transport; flagellated sperm motility; and regulation of cilium beat frequency involved in ciliary motility. Predicted to act upstream of or within fusion of sperm to egg plasma membrane involved in single fertilization and regulation of calcium ion transport. Predicted to be located in plasma membrane and sperm principal piece. 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, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Catsper1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
