HTRP-1, or Transient receptor potential cation channel, subfamily C, member 1, is a human gene encoded by TRPC1. It may also be known as: Short transient receptor potential channel 1; Transient receptor protein 1; TrpC1; TRP1. The encoded protein has an amino acid length of 793 and a mass of 91.2 kDa. Other isoforms may exist. HTRP-1 is a member of the Transient receptor (TC 1.A.4) family, STrpC subfamily, TRPC1 sub-subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
