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. Seems to be also activated by intracellular calcium store depletion.

Subunit structure

Homotetramer and heterotetramer with TRPC4 and/or TRPC5 By similarity. Interacts with TRPC3, TRPC4 and TRPC5 By similarity. Interacts with ITPR3 By similarity. Interacts with MX1 and RNF24 By similarity. Interacts with FKBP4 By similarity. Interacts with TRPC4AP. Ref.4

Subcellular location

Membrane; Multi-pass membrane protein Probable.

Sequence similarities

Belongs to the transient receptor (TC 1.A.4) family. STrpC subfamily. TRPC1 sub-subfamily. [View classification]

Contains 4 ANK repeats.

Sequence caution

The sequence AAB50622.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.

The sequence AAC53162.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.

The sequence AAF05725.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform Alpha (identifier: Q61056-1)

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: Q61056-2)

The sequence of this isoform differs from the canonical sequence as follows:
     110-143: Missing.
