General annotation (Comments)
| Function | 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. Ref.7 Ref.8 Ref.9 |
| Subcellular location | Cell membrane; Multi-pass membrane protein Potential Ref.7. |
| 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. Ref.5 Ref.6 Ref.9 |
| Induction | Up-regulated by hexamethylene bisacetamide (HBMA). Ref.6 |
| Involvement in disease | Congenital stationary night blindness 1C (CSNB1C) [MIM:613216]: A non-progressive retinal disorder characterized by impaired night vision, often associated with nystagmus and myopia. |
| Sequence similarities | Belongs to the transient receptor (TC 1.A.4) family. LTrpC subfamily. TRPM1 sub-subfamily. [View classification] |
Ontologies
Alternative products
| This entry describes 4 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 Ref.3 (identifier: Q7Z4N2-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 2 Ref.1 Ref.2 Ref.4 (identifier: Q7Z4N2-2) The sequence of this isoform differs from the canonical sequence as follows: 1-70: Missing. | ||||||
| Isoform 3 Ref.2 (identifier: Q7Z4N2-3) The sequence of this isoform differs from the canonical sequence as follows: 295-300: Missing. | ||||||
| Isoform 4 Ref.2 (identifier: Q7Z4N2-4) The sequence of this isoform differs from the canonical sequence as follows: 301-1603: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. |
