C/EBPβ-Interacting Multi-protein Complexes in HEK293T Cells
(A) Co-immunoprecipitation of FLAG-tagged C/EBPβ and the MLL/Ash2/Wdr5 complex.
(B) Left panel: FLAG-tagged C/EBPβ was co-expressed with GFP-tagged Spt16 and SSRP1. Right panel: Immunoprecipitation of FLAG-tagged C/EBPβ co-precipitates both endogenous FACT complex subunits.
(C) Interaction with the super elongation complex. Immunoprecipitation of human C/EBPβ (C/EBPβ) pulls down the entire super elongation complex.
(D) Interaction with the NuRD complex. The integral subunits of the NuRD complex MBD2 (HA-tagged) and MBD3 (GFDP-tagged) were pulled down by immunoprecipitation. Detection by western blot shows that C/EBPβ interacts with both subunits. IB, immunoblotting; IP, immunoprecipitation.
