Background

Transient receptor potential cation channel subfamily C member 6 (TRPC6) is a multi-pass transmembrane channel protein encoded by the TRPC6 gene, composed of six transmembrane helices, pore-forming extracellular loop and cytoplasmic regulatory C-terminal domain, and acts as a core pore-forming subunit for receptor-operated cation channel complexes. TRPC6 is widely expressed across contractile mesenchymal, epithelial and glomerular cell populations, serving as a core scaffold mediating channel tetramer assembly and downstream calcium-dependent kinase recruitment upon GPCR ligand stimulation.

TRPC6 exerts its biological effects through tetrameric pore assembly within plasma membranes, a mechanism that modulates cation permeation stability and intracellular calcium signal cascade activation efficiency. Unlike auxiliary channel subunits, TRPC6 cannot mediate sustained cation flux without complete tetramer formation and relies on channel oligomerization to initiate full calcium signal output; it recruits cytoplasmic signal mediators to assembled channel complexes, uncoupling extracellular receptor stimulation from intracellular calcium-dependent transcription factor activation and sustaining persistent contractile cellular signals. This dual regulation modulates the intensity of calcium-triggered tissue contractile responses after ligand stimulation, fine-tuning local cellular contraction and fibrotic mediator secretion levels, while sustained abnormal TRPC6-mediated cation conduction drives excessive extracellular matrix deposition and fibrotic lesions. TRPC6 participates in key physiological and pathological processes including receptor-operated calcium entry, cellular contractile activation, matrix-mediated tissue remodeling and chronic fibrotic disorders. Dysregulation of TRPC6 expression or channel permeation capacity is closely associated with unregulated tissue contraction and impaired matrix homeostasis, making TRPC6 a crucial research target for cation channel signaling, calcium transduction and fibrotic disease research.

TRPC6 Protein Function: Core Roles in Cation Channel Oligomerization and Calcium Homeostasis

The biological functions of TRPC6 are focused on receptor-operated cation channel assembly, calcium signal propagation and tissue matrix balance:

  • Channel Pore Modulation: Forms tetrameric cation-permeable pores at cell membranes to stabilize calcium gradient flux and amplify downstream contractile signal activity, the primary molecular mechanism of TRPC6-mediated regulation.
  • Calcium Signal Amplification: Recruits cytoplasmic signaling kinases to trigger calcium-dependent transcription factor activation, fine-tuning cellular contractile response dynamics.
  • Fibrotic Mediation: Supports sustained secretion of matrix mediators to coordinate local tissue remodeling reactions.
  • Tissue Contractile Homeostasis: Strengthens GPCR-triggered calcium signaling to maintain balanced tissue contractile surveillance.
  • Disease Relevance: Abnormal TRPC6 expression is closely related to excessive matrix deposition and chronic fibrotic pathologies, making it a key target for calcium channel signaling research.
