General annotation (Comments)
| Function | Thought to form a receptor-activated non-selective calcium permeant cation channel. Probably is operated by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases or G-protein coupled receptors. Activated by diacylglycerol (DAG) in a membrane-delimited fashion, independently of protein kinase C, and by inositol 1,4,5-triphosphate receptors (ITPR) with bound IP3 By similarity. May also be activated by internal calcium store depletion. |
| Subunit structure | Interacts with TRPC1, ITPR1, ITPR3, MX1 and RNF24. Interacts with JPH2; the interaction is involved in maintaining Ca2+ homeostasis in skeletal muscle and is mediated by JPH2 'Ser-165' phosphorylation By similarity. |
| Subcellular location | Membrane; Multi-pass membrane protein Probable. |
| Sequence similarities | Belongs to the transient receptor (TC 1.A.4) family. STrpC subfamily. TRPC3 sub-subfamily. [View classification] Contains 4 ANK repeats. |
| Sequence caution | The sequence BAA93434.1 differs from that shown. Reason: Chimeric cDNA. |
