Activity summary

TRPC6 TRPC3 and TRPC5 are members of the transient receptor potential (TRP) channel family. These proteins function as non-selective cation channels allowing the passage of calcium ions and other cations such as sodium. TRPC channels often respond to various chemical and mechanical stimuli. TRPC6 TRPC3 and TRPC5 have molecular masses of approximately 106 kDa 97 kDa and 105 kDa respectively. They express widely in tissues such as the brain heart kidneys and to a lesser degree in the vasculature. Each of these proteins forms homo- or heteromeric complexes which modulate their functional diversity.

Biological function summary

These channels participate in important cellular processes maintaining ion homeostasis and influencing cellular responses. TRPC6 TRPC3 and TRPC5 contribute to receptor-operated calcium entry (ROCE) playing a significant role in the physiological regulation of calcium levels. They form part of multimeric channel complexes with other TRPC subunits influencing vascular smooth muscle contraction and neuronal signaling. These proteins also interact with other channels and cellular components including the NCX (sodium-calcium exchanger) which further delineates their role in cellular calcium handling.

Pathways

TRPC6 TRPC3 and TRPC5 integrate into the PIP2 pathway and calcium signaling pathways. These channels interact with phospholipase C to generate inositol trisphosphate and diacylglycerol key second messengers that propagate cellular signals. In the context of these pathways TRPC channels associate closely with proteins such as NCX and PLC modulating intracellular calcium dynamics. This interaction is critical for many cellular processes including smooth muscle contraction and neuronal activity.

Associated diseases and disorders

TRPC channels particularly TRPC6 and TRPC3 are associated with disorders like focal segmental glomerulosclerosis (FSGS) and cardiac hypertrophy. Mutations or dysregulation of TRPC channels can lead to abnormal calcium signaling contributing to the pathophysiology of these conditions. In these disease states TRPC channels interact with key proteins such as podocin in kidney diseases or calcineurin in cardiac hypertrophy influencing cellular outcomes and tissue pathology. Understanding the detailed mechanisms of these interactions helps in developing targeted therapeutic strategies.
