Detection of Human FKBP52 by Western Blot. Western blot shows lysates of MCF-7 human breast cancer cell line. PVDF membrane was probed with 1 µg/mL Rat Anti-Human FKBP52 Monoclonal Antibody (Catalog # MAB4095) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). For additional reference, 5 ng recombinant human FKBP38, FKBP51, and FKBP52 were included. A specific band for FKBP52 was detected at approximately 62 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

FK506 binding protein, also called FKBP52 and FKBP4, is a peptidyl-prolyl isomerase that catalyzes the transition between cis- and trans- proline residues critical for proper folding of proteins. It associates with HSP90 complexes that are critical for the proper folding of steroid receptors. FKBP52 knockout mice have abnormal reproductive organ development due to disruption of androgen receptor folding; and phosphorylation of FKBP52 at Thr143 seems important for steroid receptor activity.
