(A) A heat map showing the 71 DNA-interacting proteins that were co-immunoprecipitated with only RUNX3 (cluster 1), RUNX1 and RUNX3 (cluster 2), or only RUNX1 (cluster 3) from transduced 1200M cells. (B) A list of the transcription factors, DNA methyltransferases, and histone modifying enzymes in (A). (C) Immunoblotting (IB) for RUNX proteins co-immunoprecipitated with FLAG-G9a from lysates of AKR1 cells transduced with RUNX1, RUNX3 or FLAG-G9a. Blots are representative of 2 experiments.
