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. May also be activated by internal calcium store depletion. Ref.1 Ref.9 Ref.11 Ref.15 |
| 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. Ref.10 Ref.12 Ref.13 Ref.14 Ref.15 |
| Subcellular location | |
| Tissue specificity | Expressed predominantly in brain and at much lower levels in ovary, colon, small intestine, lung, prostate, placenta and testis. |
| Sequence similarities | Belongs to the transient receptor (TC 1.A.4) family. STrpC subfamily. TRPC3 sub-subfamily. [View classification] Contains 4 ANK repeats. |
