Protein: Transient receptor potential cation channel subfamily M member 1 (Long transient receptor potential channel 1) (LTrpC1) (Melastatin-1) (Q2TV84)
Organism: Mus musculus (Mouse)
Function: Forms nonselective divalent cation-conducting channels which mediate the influx of Na(2+), Ca(2+), Mg(2+), Mn(2+), Ba(2+), and Ni(2+) into the cytoplasm, leading to membrane depolarization (By similarity). Impermeable to zinc ions (By similarity). In addition, forms heteromultimeric ion channels with TRPM3 which are permeable for calcium and zinc ions (By similarity). Essential for the depolarizing photoresponse of retinal ON bipolar cells. It is part of the GRM6 signaling cascade. Calcium channel which may play a role in metastasis suppression. May act as a spontaneously active, calcium-permeable plasma membrane channel.
Subcellular location: Cell membrane {ECO:0000250|UniProtKB:Q7Z4N2}; Multi-pass membrane protein {ECO:0000255}. Endoplasmic reticulum membrane {ECO:0000269|PubMed:30027108}; Multi-pass membrane protein {ECO:0000255}. Cell projection, axon {ECO:0000269|PubMed:30027108}. Note=In ON-bipolar cells is intracellular and located predominantly in the ER, and not at the plasma membrane or Golgi apparatus. {ECO:0000250|UniProtKB:Q7Z4N2}.
