ABSTRACT:
FK506 and geldanamycin promote nerve regeneration by a common mechanism that involves the binding of these compounds to polypeptide components of steroid receptor complexes other than the steroid hormone binding portion of the complex (FKBP52 and hsp90, respectively). These and other agents cause hsp90 dissociation from steroid receptor complexes or block association of hsp90 with steroid receptor complexes.
