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 catsper-related male infertility. Among its related pathways are Sweet Taste Signaling and Reproduction. GO annotations related to this gene include voltage-gated calcium channel activity.

UniProtKB/Swiss-Prot 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. Activated by extracellular progesterone and prostaglandins following the sequence: progesterone > PGF1-alpha = PGE1 > PGA1 > PGE2 >> PGD2. 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. Sperm capacitation enhances the effect of progesterone by providing additional negative shift. Also activated by the elevation of intracellular pH.

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. Activated by extracellular progesterone and prostaglandins following the sequence: progesterone > PGF1-alpha = PGE1 > PGA1 > PGE2 >> PGD2. 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. Sperm capacitation enhances the effect of progesterone by providing additional negative shift. Also activated by the elevation of intracellular pH.
UniProtKB/Swiss-Prot Induction: Down-regulated in patients lacking sperm motility.
