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. For more details see Group:MUZIC:Calcineurin.
