FKBP25 interacts with the pre-60S ribosome in the presence of nucleolin. (A) Sucrose density gradient ultracentrifugation of HEK293 nuclear extract. RNA and protein were extracted from each fraction and were resolved by denaturing-formaldehyde gel electrophoresis or SDS-PAGE and Western blot. (B) Sucrose density gradient ultracentrifugation of FLAG-FKBP25 immunoprecipitate from HEK293 cells. RNA and protein were extracted from each fraction and were resolved by denaturing formaldehyde gel electrophoresis or SDS-PAGE and Western blot.
