Summaries for CATSPER1 Gene

Entrez Gene Summary 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. GO annotations related to this gene include ion channel activity and calcium activated cation channel activity. An important paralog of this gene is CACNA1B.

UniProtKB/Swiss-Prot for CATSPER1 Gene

Function for CATSPER1 Gene

Molecular function for CATSPER1 Gene

UniProtKB/Swiss-Prot EnzymeRegulation:
The CatSper calcium channel is indirectly activated by extracellular progesterone and prostaglandins following the sequence: progesterone > PGF1-alpha = PGE1 > PGA1 > PGE2 >> PGD2 (PubMed:21412338, PubMed:21412339, PubMed:26989199). The CatSper calcium channel is directly inhibited by endocannabinoid 2-arachidonoylglycerol (2AG) (PubMed:26989199). Indirect activation by progesterone takes place via the following mechanism: progesterone binds and activates the acylglycerol lipase ABHD2, which in turn mediates hydrolysis of 2AG inhibitor, relieving inhibition of the CatSper channel (PubMed:26989199). The primary effect of progesterone activation is to shift voltage dependence towards more physiological, negative membrane potentials; it is not mediated by metabotropic receptors and second messengers (PubMed:21412338, PubMed:21412339). Sperm capacitation enhances the effect of progesterone by providing additional negative shift. Also activated by the elevation of intracellular pH (PubMed:21412338, PubMed:21412339).
UniProtKB/Swiss-Prot Function:
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.
UniProtKB/Swiss-Prot Induction:
Down-regulated in patients lacking sperm motility.
