evidence: Zinc-activated ion channel -LRB- ZAC -RRB- , is a human protein encoded by the gene .. protein. protein. gene. gene. ZAC forms a cation-permeable ligand-gated ion channel of the `` Cys-loop '' superfamily .. ligand-gated ion channel. ligand-gated ion channel. ligand. ligand. The ZAC gene is present in humans and dogs , but no ortholog is thought to exist in the rat or mouse genomes .. gene. gene. ZAC mRNA is expressed in prostate , thyroid , trachea , lung , brain -LRB- adult and fetal -RRB- , spinal cord , skeletal muscle , heart , placenta , pancreas , liver , kidney and stomach .. The endogenous ligand for ZAC is thought to be Zn2 + , although ZAC has also been found to activate spontaneously .. ligand. ligand. The function of spontaneous ZAC activation is unknown .
