TRPC6
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]
Interactions
TRPC6 has been shown to interact with:
Ligands
Two of the primary active constituents responsible for the antidepressant and anxiolytic benefits of Hypericum perforatum, also known as St. John's Wort, are hyperforin and adhyperforin.[5][6] These compounds are inhibitors of the reuptake of serotonin, norepinephrine ,dopamine, γ-aminobutyric acid, and glutamate, and they exert these effects by binding to and activating TRPC6.[6][7] Activation of TRPC6 induces the entry of Ca2+ and Na+ into the cell, which results in the inhibition of reuptake.[7]
