<!--
'''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.

'''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.
