== Function ==
[https://www.uniprot.org/uniprot/SL9C1_STRPU SL9C1_STRPU] 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.<ref>PMID:30022052</ref> <ref>PMID:37880360</ref> <ref>PMID:37880361</ref>
