This study investigates the effects of p300 on Rev-erba protein levels in transfected 293T cells. Cells were treated with cycloheximide and harvested at specified time points to assess protein levels through Western blot analysis. Both wild-type (WT) and mutant forms of HA-Rev-erba (K591A, K400A) were evaluated in the presence or absence of p300. This allows for the understanding of how p300 influences Rev-erba stability and expression, shedding light on the molecular interactions in cellular contexts.
