Function

The protein encoded by this gene is similar to the transient receptor potential (Trp) calcium channel family members. The expression of this protein is inversely correlated with melanoma aggressiveness, suggesting that it suppresses melanoma metastasis.^[4] The expression of the TRPM1 gene is regulated by the Microphthalmia-associated transcription factor.^[5]^[6]

Clinical significance

Mutations in TRPM1 are associated with congenital stationary night blindness and coat spotting patterns in Appaloosa horses.^[7]
