CC -!- FUNCTION: Thought to form non-selective a receptor-activated calcium
CC permeant cation channel. Probably is operated by a phosphatidylinositol
CC second messenger system activated by receptor tyrosine kinases or G-
CC protein coupled receptors. Acts as a cell-cell contact-dependent
CC endothelial calcium entry channel. Has also been shown to be calcium-
CC selective (By similarity). May also be activated by intracellular
CC calcium store depletion. {ECO:0000250}.
CC -!- SUBUNIT: Homotetramer and heterotetramer with TRPC1 and/or TRPC5
CC (PubMed:12857742). Isoform alpha but not isoform beta interacts with
CC ITPR1, ITPR2 and ITPR3 (By similarity). Interacts with SLC9A3R1/NHERF
CC (By similarity). Interacts with MX1 and RNF24 (By similarity).
CC Interacts (via CIRB domain) with SESTD1 (via the spectrin 1 repeat) and
CC SPTBN5 (via C-terminus) (By similarity). Interacts with CDH5 and CTNNB1
CC (By similarity). Interacts (via protein 4.1-binding domain) with
CC EPB41L2 (By similarity). Interacts with TRPC4AP (By similarity).
CC Interacts with PLSCR1 (By similarity). {ECO:0000250|UniProtKB:Q9QUQ5,
CC ECO:0000250|UniProtKB:Q9UBN4, ECO:0000269|PubMed:12857742}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}. Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=Alpha;
CC IsoId=O35119-1; Sequence=Displayed;
CC Name=Beta;
CC IsoId=O35119-2; Sequence=VSP_006571;
CC -!- SIMILARITY: Belongs to the transient receptor (TC 1.A.4) family. STrpC
CC subfamily. TRPC4 sub-subfamily. {ECO:0000305}.
