TRPV5 encodes the human gene, Transient receptor potential cation channel, subfamily V, member 5. It may also be known as: Transient receptor potential cation channel subfamily V member 5; Calcium transport protein 2; Epithelial calcium channel 1; Osm-9-like TRP channel 3; OTRPC3; TrpV5; ECAC1. The encoded protein has an amino acid length of 729 and a mass of 82.6 kDa. Other isoforms may exist. TRPV5 is a member of the Transient receptor (TC 1.A.4) family, TrpV subfamily, TRPV5 sub-subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog.
