YY1-dependent chromatin structure stabilization of B lineage commitment
During B cell lineage commitment, a dynamic shift of genes between transcriptionally restricted and transcriptionally permissive compartments at the pre-pro-B to pro-B cell transition results in activation of the B lineage program and repression of alternative lineage programs. While B lineage commitment is generally believed to be driven by lineage-specific transcription factors, we have made the surprising discovery that conditional knock-out of the ubiquitous transcription factor YY1 results in loss of B lineage commitment, allowing subsequent development into the T cell lineage both in vitro and in vivo. Pioneer transcription factors such as Ebf1 promote transcription of B lineages…
