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.6 Ref.8 Ref.12

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.7 Ref.9 Ref.10 Ref.11 Ref.12

Subcellular location

Membrane; Multi-pass membrane protein.

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.
