Transient receptor potential cation channel, subfamily C, member 6 or Transient receptor potential canonical 6, also known as TRPC6, is a protein encoded in the human by the TRPC6gene. TRPC6 is a transient receptor potential channel of the classical TRPC subfamily.[5]
Unlike the closely related TRPC3 channels, TRPC6 channels possess the distinctive ability to transport heavy metal ions. TRPC6 channels facilitate the transport of zinc ions, promoting their accumulation inside cells.[6][7]
In addition, despite their non-selectiveness, TRPC6 exhibits a strong preference for calcium ions, with a permeability ratio of calcium to sodium (PCa/PNa) of roughly six. This selectivity is significantly higher compared to TRPC3, which displays a weaker preference for calcium with a (PCa/PNa) ratio of only 1.1.[6]
