FKBP51 Polyclonal Antibody

The immunophilins are a highly conserved family of cis-trans peptidyl-prolyl isomerases that bind to and mediate the effects of immunosuppressive drugs, such as cyclosporin, FK506 and rapamycin (1) . Several related immunophilins, FKBP12, FKBP51 and FKBP52, are characterized as cytosolic FK506-binding proteins, and following ligand binding, they functionally inhibit the phosphatase activity of calcineurin (2,3) . The ubiquitously expressed FKBP12 also associates with the cytoplasmic domain of the TGF?type I receptor, where it stabilizes the inactive conformation of the receptor and blocks the activation of the TGF?pathway (4) . FKBP51 and FKBP52 are two highly related proteins (5,6) . FKBP51 is predominantly expressed in T cells and is induced by glucocorticoids (5) . FKBP51 mediates the effects of FK506 and rapamycin by inhibiting intracellular calcineurin activity, and by blocking T-cell activation and proliferation (7) . FKBP52, known also as FKBP-59 or heat shock protein 56, is expressed in a variety of tissues and can also associate with the heat shock protein (hsp90) in mature steroid receptor complexes (6,8) .
