Background:  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. FKBPL (FK506-binding protein-like), also known as WAF-1/CIP1 stabilizing protein 39 and DIR1, is a 349 amino acid immunophilin protein that recruits Hsp90 to stabilize p21 by preventing its proteosomal degradation. After ionizing radiation, FKBPL is transiently repressed and may play a role in induced radioresistance through a mechanism that increases rate of DNA repair in X ray exposed cells. siRNA knockdown of FKBPL results in decreased levels of cell cycle inhibitor p21WAF1 and increased ER-α phosphorylation in response to 17β-estradiol and tamoxifen. This evidence suggests that FKBPL may have an impact on tumor proliferative capacity and sensitivity to endocrine therapies.
