USP36 stabilizes ALKBH5 by inhibiting its ubiquitination. (A) 293T cells were transfected with indicated plasmids or specific siRNA. Cell lysates were immunoprecipitated with anti-HA antibody and then analyzed by immunoblotting. (B) 293T cells were transfected with indicated plasmids, and followed by treatment with MG132 for 6 hours before cell harvest. Cell lysates were immunoprecipitated with anti-HA antibody and then analyzed by immunoblotting using the indicated antibodies. (C) The endogenous ubiquitination of ALKBH5 was analyzed in USP36-knockout GSC17 cells after transfected with HA-Ubi. Cell lysates were immunoprecipitated with anti-HA antibody and then analyzed by immunoblotting using the indicated antibodies. (D) 293T cells were transfected with His-ALKBH5 and HA-Ubi and then treated with MG132 for 6 hours. ALKBH5 protein was purified using the magnetic bead. The ubiquitinated ALKBH5 was then incubated with 50 ng or 500 ng USP36 in a deubiquitination buffer. The resulting reactions were subjected to immunoblotting analysis.
