Short transient receptor potential channel 5 (TrpC5) also known as transient receptor protein 5 (TRP-5) is a protein that in humans is encoded by the TRPC5 gene.[1][1][2] TrpC5 is subtype of the TRPC family of mammalian transient receptor potential ion channels.

Function

TrpC5 is one of the seven mammalian TRPC (transient receptor potential canonical) proteins. TrpC5 is a multi-pass membrane protein and is thought to form a receptor-activated non-selective calcium permeant cation channel. The protein is active alone or as a heteromultimeric assembly with TRPC1, TRPC3, and TRPC4. It also interacts with multiple proteins including calmodulin, CABP1, enkurin, Na+–H+ exchange regulatory factor (NHERF), interferon-induced GTP-binding protein (MX1), ring finger protein 24 (RNF24), and SEC14 domain and spectrin repeat-containing protein 1 (SESTD1).[3]

TRPC4 and TRPC5 have been implicated in the mechanism of mercury toxicity[4] and neurological behavior.[5]

Activation

Homomultimeric TRPC5 and heteromultimeric TRPC5-TRPC1 channels are activated by extracellular reduced thioredoxin.[6] This channel has also been found to be involved in the action of anaesthetics such as chloroform, halothane and propofol.[7]

Interactions

TRPC5 has been shown to interact with STMN3,[8] TRPC1,[9][10] and TRPC4.[10]
