Zinc-activated ion channel (ZAC), is a human protein encoded by the ZACN gene. ZAC forms a cation-permeable ligand-gated ion channel of the "Cys-loop" superfamily. The ZAC gene is present in humans and dogs, but no ortholog is thought to exist in the rat or mouse genomes.[3]

ZAC mRNA is expressed in prostate, thyroid, trachea, lung, brain (adult and fetal), spinal cord, skeletal muscle, heart, placenta, pancreas, liver, kidney and stomach.[3][4] The endogenous ligand for ZAC is thought to be Zn²⁺, although ZAC has also been found to activate spontaneously. The function of spontaneous ZAC activation is unknown.[3]
