Abstract

Among the “classical” or “canonical” transient receptor potential (TRPC) family, the TRPC3, -6, and -7 channels share 75% amino acid identity and are gated by exposure to diacylglycerol. TRPC3, TRPC6, and TRPC7 interact physically and coassemble to form functional tetrameric channels. This review focuses on the TRPC3/6/7 subfamily and describes their functional properties and regulation as homomers obtained from overexpression studies in cell lines. It also summarizes their heteromultimerization potential in vitro and in vivo and presents initial data concerning their physiological functions analyzed in isolated tissues with downregulated channel activity and gene-deficient mouse models.
