General description

Calcineurin/PP2B Aβ, also known as Serine/threonine-protein phosphatase 2B catalytic subunit beta isoform, and encoded by the gene PPP3CB/CALNA2/CALNB/CNA2, is a calcium dependent, calmodulin stimulated catalytic subunit protein phosphatase critical in the function of Calcineurin an important phosphatase governing immune responses such as T cell activation and the T cell immune response. Calcineurin is a heterodimeric protein consisting of a catalytic subunit Calcineurin A, which contains an active site dinuclear metal center, and a tightly associated, myristoylated, Ca(2+)-binding subunit, Calcineurin B. Calcineurin/PP2B Aβ is the beta isoform of the catalytic active site of the subunit A of Calcineurin. Calcineurin also plays pivotal roles in signaling transduction cascades in a variety of other immune cells as well as non-immune cells like myocytes and neurons.
