ChIP-seq of pro-B cells to test the role of phase separation in EBF1 pioneering function

EBF1 is a transcription factor crucial for early B cell development. The phase separation ability of the EBF1 C-terminal domain (CTD) is essential for the transcription activation and pioneering function of EBF1. We identified the specific tyrosine residues in the CTD required for phase separation. We transduced pro-B cells with EBF1 wt, deletion of the entire CTD (dC), or mutation of these tyrosines (YmA). We performed ChIP-seq, ATAC-seq, and RNA-seq to see the effect of disrupting phase separation ability on DNA binding, chromatin opening, and target gene expression. Our findings confirm that phase separation is important for the EBF1 function. Overall design: EBF1 and BRG1 ChIP-seq in EBF1 wt, dC, or YmA pro-B cells
