Entrez Gene Summary for TRPM1 Gene

  • This gene encodes a member of the transient receptor potential melastatin subfamily of transient receptor potential ion channels. The encoded protein is a calcium permeable cation channel that is expressed in melanocytes and may play a role in melanin synthesis. Specific mutations in this gene are the cause autosomal recessive complete congenital stationary night blindness-1C. The expression of this protein is inversely correlated with melanoma aggressiveness and as such it is used as a prognostic marker for melanoma metastasis. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2011]

GeneCards Summary for TRPM1 Gene

TRPM1 (Transient Receptor Potential Cation Channel, Subfamily M, Member 1) is a Protein Coding gene. Diseases associated with TRPM1 include night blindness, congenital stationary , 1c, autosomal recessive and melanoma metastasis. Among its related pathways are CREB Pathway and Ion channel transport. GO annotations related to this gene include calcium channel activity. An important paralog of this gene is TRPM8.

UniProtKB/Swiss-Prot for TRPM1 Gene

  • Cation channel essential for the depolarizing photoresponse of retinal ON bipolar cells. It is part of the GRM6 signaling cascade. May play a role in metastasis suppression (By similarity). May act as a spontaneously active, calcium-permeable plasma membrane channel.

mRNA Expression by UniProt/SwissProt for TRPM1 Gene

Tissue specificity: Expressed in the retina where it localizes to the outer plexiform layer. Highly expressed in benign melanocytic nevi and diffusely expressed in various in situ melanomas, but not detected in melanoma metastases. Also expressed in melanocytes and pigmented metastatic melanoma cell lines. In melanocytes expression appears to be regulated at the level of transcription and mRNA processing.
