Summaries for CATSPER2 Gene

Entrez Gene Summary for CATSPER2 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. This gene is part of a tandem repeat on chromosome 15q15; the second copy of this gene is thought to be a pseudogene. Alternatively spliced transcript variants have been found for this gene.

GeneCards Summary for CATSPER2 Gene

CATSPER2 (Cation Channel, Sperm Associated 2) is a Protein Coding gene. Diseases associated with CATSPER2 include deafness-infertility syndrome and catsper-related male infertility. Among its related pathways are Sweet Taste Signaling and Reproduction. GO annotations related to this gene include calcium channel activity and voltage-gated ion channel activity.

UniProtKB/Swiss-Prot for CATSPER2 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.
