BD, 610259, Purified Mouse Anti-Calcineurin 29/Calcineurin

Calcineurin is a Ca2+/calmodulin-dependent protein phosphatase. The active enzyme is a heterodimer of a large calmodulin-binding catalytic subunit A (61 kDa) and a smaller Ca2+ binding subunit B (19 kDa). Regions corresponding to the calmodulin-binding site, an autoinhibitory domain, and a putative subunit B binding site have been identified within the large subunit A. The activity of calcineurin is sensitive to immunosuppressants such as cyclosporin A (CsA) and tacrolimus (FK506). The study of FK506-mediated inhibition of nitric oxide formation has revealed that nitric oxide synthase (NOS) is a calcineurin substrate. Calcineurin dephosphorylates NOS and enhances its catalytic activity. Therefore, Calcineurin is an essential mediator for efficient T cell antigen receptor (TCR)-mediated T cell activation.
