Potassium channel subfamily U member 1

UniProtKB accession:  A8MYU2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Testis-specific potassium channel activated by both intracellular pH and membrane voltage that mediates export of K(+) (PubMed:23129643, PubMed:24670955, PubMed:36649421, PubMed:38267364, PubMed:9452476). Represents the primary spermatozoan K(+) current. The channel underlies a pH-triggered membrane hyperpolarization during the process of sperm capacitation, as sperm encounter the alkaline environment near the ovum in the female reproductive tract, thereby playing an essential for male fertility (PubMed:34980136, PubMed:35551387, PubMed:36649421).
