TRPC channels: Structure, function, regulation and recent advances in small molecular probes.

Area of Science:

• Ion channel research
• Molecular biology
• Pharmacology

Background:

• Transient receptor potential canonical (TRPC) channels are calcium-permeable cation channels involved in diverse cellular functions.
• TRPC channels are classified into four subgroups and play significant physiological roles.
• Their complex regulation involves phospholipase C pathway, G-proteins, and internal calcium stores.

Purpose of the Study:

• To review recent advancements in TRPC channel understanding.
• To cover TRPC channel regulation, structure, and novel small molecule probes.
• To facilitate drug discovery and therapeutic development for TRPC-related diseases.

Main Methods:

• Cryo-electron microscopy for high-resolution structures.
• Analysis of genetic mutations linking TRPC6 to kidney disease.
• Discovery and characterization of novel TRPC-targeting small molecules.

Main Results:

• High-resolution structures of TRPC channels have been elucidated.
• TRPC6 mutations are linked to familial focal segmental glomerulosclerosis.
• Potent synthetic and natural compounds targeting TRPC subtypes have been identified.

Conclusions:

• TRPC channel research is rapidly advancing, particularly in pharmacology.
• Novel TRPC probes and preclinical candidates show therapeutic potential.
• Further research aims to leverage TRPC understanding for drug discovery.
