PP1δ interacts with nucleophosmin. Whole cell lysate prepared from Saos-2 cells was immunoprecipitated with the anti-PP1δ antibody and normal rabbit IgG (A) or with the anti-nucleophosmin (NPS) antibody and normal goat IgG (B). The immunoprecipitants were analysed by Western blotting using the anti-NPS antibody (A) or anti-PP1δ antibody (B). As a positive control, whole cell lysate was used as input.
