We have previously shown that immunoadsorption of the FKBP52 immunophilin component of steroid receptor⅐hsp90 heterocomplexes is accompanied by coadsorption of cytoplasmic dynein, a motor protein involved in retrograde transport of vesicles toward the nucleus. Coimmunoadsorption of dynein is competed by an expressed fragment of FKBP52 comprising its peptidylprolyl isomerase (PPIase) domain (Silverstein, A. M.,
