Fig. 6. USP8 promoted ubiquitination and degradation of TAK1.

Fig. 6

A The protein levels of USP8 and TAK1 were examined by western blot in KCs overexpressing control (NC) or USP8. B The interaction between USP8 and TAK1 was examined by Co-IP in HEK293T cells co-transfected with Myc-tagged TAK1 and Flag-tagged USP8 (left and middle panels). C The interaction between endogenous USP8 and Myc-TAK1, and that between endogenous TAK1 and Flag-USP8 was examined by Co-IP in HEK293T cells. D KCs were transfected with Myc-TAK1 and treated with or without MG132. The level of TAK1 was examined by western blot. E KCs cells from D were treated with cycloheximide (CHX) for indicated time periods. The expression of TAK1 was examined by western blot. F si-NC- or si-USP8-transfected KCs were treated with CHX for indicated time periods. The protein levels of TAK1 and USP8 were examined by western blot.
