General annotation (Comments)

Function

Thought to form non-selective a receptor-activated calcium permeant cation channel. Probably is operated by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases or G-protein coupled receptors. Acts as a cell-cell contact-dependent endothelial calcium entry channel. Has also been shown to be calcium-selective By similarity. May also be activated by intracellular calcium store depletion.

Subunit structure

Homotetramer and heterotetramer with TRPC1 and/or TRPC5. Heteromers containing TRPC3 or TRPC6 are also found exclusively in embryonic brain. Isoform alphabut not isoform betaassociates with inositol 1,4,5-trisphosphate receptor (ITPR). Interacts with NHERF By similarity. Interacts with MX1 and RNF24 By similarity. Interacts (via CIRB domain) with SESTD1 (via the spectrin 1 repeat) and SPTBN5 (via C-terminus) By similarity. Interacts with CDH5 and CTNNB1 By similarity. Interacts (via protein 4.1-binding domain) with EPB41L2 By similarity. Interacts with TRPC4AP By similarity. Ref.4

Subcellular location

Membrane; Multi-pass membrane protein Probable. Cell membrane; Multi-pass membrane protein By similarity.

Sequence similarities

Belongs to the transient receptor (TC 1.A.4) family. STrpC subfamily. TRPC4 sub-subfamily. [View classification]

Contains 4 ANK repeats.

Sequence caution

The sequence BAA23599.2 differs from that shown. Reason: Frameshift at positions 121 and 412.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform Alpha (identifier: O35119-1)

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.
Isoform Beta (identifier: O35119-2)

The sequence of this isoform differs from the canonical sequence as follows:
     784-867: Missing.
