JUN and infection: Of the 227 BRD4 interactors that were recruited to the BRD4 complex during RSV-infection, we observe that 95 ( 42%) are disrupted to some degree by treatment with ZL0454, including most of the transcription factors described in the earlier section (e.g., c-JUN, CTNNB1, JUP, DDX3X, MTDH).
