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. Has also been shown to be calcium-selective By similarity. May also be activated by intracellular calcium store depletion. TRPC4 deficient mice lack a store-operated calcium entry in endothelial cells.

Subunit structure

Isoform alpha but not isoform beta associates with inositol-1,4,5-triphosphate receptor (ITPR) By similarity. Interacts with NHERF. Interacts with MX1 and RNF24 By similarity.

Subcellular location

Membrane; Multi-pass membrane protein Probable.

Tissue specificity

Abundantly expressed in brain (hippocampal CA1 pyramidal neurons, dentate gyrus granule cells, and cerebral cortical neurons, and in the septal nuclei and the mitral layer of olfactory bulb). Lower levels are detected in other tissues.

Sequence similarities

Belongs to the transient receptor family. STrpC subfamily.

Contains 2 ANK repeats.
