Detection of Human/Mouse/Rat Calcineurin A by Western Blot. Western blot shows lysates of HT-29 human colon adenocarcinoma cell line, TS1 mouse helper T cell line, and Nb2‑11 rat lymphoma cell line. PVDF membrane was probed with 1 µg/mL Rat Anti-Human/Mouse/Rat Calcineurin A Monoclonal Antibody (Catalog # MAB2839) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). For additional reference, Recombinant Human Calcineurin (Catalog # 3160-CA) (1 ng) was included. A specific band for Calcineurin A was detected at approximately 59 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Calcineurin A
Calcineurin A, also known as PP2B and PPP3CA, is the 59 kDa catalytic subunit of the calcium/calmodulin-dependent protein phosphatase. When activated by calcium in the presence of the regulatory B subunit and calmodulin, Calcineurin A selectively removes phosphates from serine and threonine residues on target proteins. Although ubiquitously expressed, Calcineurin levels are highest in brain, where the phosphatase plays a role in the formation and retention of memories. Calcineurin activity is inhibited by the immunosuppressant drug cyclosporine A bound to cyclophilins.
