TRPM4 is a symbol for the gene, Transient receptor potential cation channel, subfamily M, member 4, in humans. Other names include: Transient receptor potential cation channel subfamily M member 4; Calcium-activated non-selective cation channel 1; Long transient receptor potential channel 4; LTrpC-4; LTrpC4; Melastatin-4; hTRPM4; TRPM4B. The encoded protein has an amino acid length of 1214 and a mass of 134.3 kDa. Other isoforms may exist. TRPM4 is a member of the Transient receptor (TC 1.A.4) family, LTrpC subfamily, TRPM4 sub-subfamily. This gene shares homology with other species, including: Mouse, Zebrafish.
