Calcineurin (CN) is a eukaryotic calcium-dependent serine/threonine protein phosphatase 2B which dephosphorylates serine/threonine residues. CN activates T cells of the immune system. It participates in Ca+2-dependent signal transduction pathways. It contains a calmodulin-binding catalytic subunit and a Ca+2-binding regulatory subunit. There are 2 metal ions in CN active site. CN inhibitors are used as drugs in cases of rheumatic diseases, schizophrenia and diabetes. It is inhibited by immunosuppressant drugs like cyclosporine.
