Transient receptor potential cation channel subfamily M member 1 is a protein that in humans is encoded by the TRPM1 gene.
The protein encoded by this gene is a member of the transient receptor potential (TRP) family of non-selective cation channels. The expression of this protein is inversely correlated with melanoma aggressiveness, suggesting that it suppresses melanoma metastasis. The expression of the TRPM1 gene is regulated by the Microphthalmia-associated transcription factor.
Mutations in TRPM1 are associated with congenital stationary night blindness in humans and coat spotting patterns in Appaloosa horses.
