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] See more...

Function for CATSPER1 Gene

Molecular function for CATSPER1 Gene

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 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 Induction:
Down-regulated in patients lacking sperm motility.
