Previous GeneCards Identifiers for CATSPER1 Gene
Calcium ions play a primary role in the regulation of sperm motility. This gene belongs to a family of putative cation channels that are specific to spermatozoa and localize to the flagellum. The protein family features a single repeat with six membrane-spanning segments and a predicted calcium-selective pore region. [provided by RefSeq, Jul 2008]
GeneCards Summary for CATSPER1 Gene
CATSPER1 (Cation Channel Sperm Associated 1) is a Protein Coding gene. Diseases associated with CATSPER1 include Spermatogenic Failure 7 and Non-Syndromic Male Infertility Due To Sperm Motility Disorder. Among its related pathways are Fertilization and Sweet Taste Signaling. Gene Ontology (GO) annotations related to this gene include ion channel activity and calcium activated cation channel activity. An important paralog of this gene is SCN3A.
UniProtKB/Swiss-Prot Summary for CATSPER1 Gene
Voltage-gated calcium channel that plays a central role in calcium-dependent physiological responses essential for successful fertilization, such as sperm hyperactivation, acrosome reaction and chemotaxis towards the oocyte.
