Transient receptor potential cation channel, subfamily C, member 6, also known as TRPC6, is a human gene encoding a protein of the same name. TRPC6 is a transient receptor potential ion channel. It has been associated with depression and anxiety (see below), as well as with focal segmental glomerulosclerosis (FSGS).[1]



TRPC6 has been shown to interact with TRPC2,[2] FYN,[3] and TRPC3.[4]


Two of the primary active constituents responsible for the antidepressant and anxiolytic benefits of Hypericum perforatum (St. John's Wort) are hyperforin and adhyperforin.[5][6] These compounds are inhibitors of the reuptake of serotonin, norepinephrine (noradrenaline) and epinephrine (adrenaline), dopamine, gamma-aminobutyric acid (GABA), and glutamate, and they exert these effects by binding to and activating TRPC6.[6][7] Activation of TRPC6 induces the entry of calcium (Ca2+) and sodium (Na+) into the cell, which results in the reuptake inhibition.[7]
