Gene Gene information from NCBI Gene database.
Entrez ID 157855
Gene name Potassium calcium-activated channel subfamily U member 1
Gene symbol KCNU1
Synonyms (NCBI Gene)
KCNMC1KCa5KCa5.1Kcnma3SPGF79Slo3
Chromosome 8
Chromosome location 8p11.23
Summary This gene encodes a member of the potassium channel family of proteins. The encoded voltage-gated ion channel allows the outward flow of potassium ions during plasma membrane hyperpolarization in sperm. Opening of this channel may be regulated by calcium
