Sperm-specific sodium:proton exchanger

UniProtKB accession:  A3RL54

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Electroneutral sodium:proton antiporter that regulates intracellular pH of sperm along with capacitation and fertility. Activated in response to egg-derived chemoattractants, couples membrane voltage to sodium:proton exchange and transduces membrane hyperpolarization to cytoplasmic alkalization to cAMP signaling and ultimately to sperm motility.
