TOBF1 modulates mouse embryonic stem cell fate through co-transcriptional regulation of alternative splicing
Abstract Embryonic stem (ES) cells retain the ability to undergo lineage-specific differentiation that can eventually give rise to different cell types that constitute an organism. Although stem cell specific biological networks of transcription factors and epigenetic modifiers are well established, how the ES cell specific transcriptional and alternative splicing (AS) machinery regulate their expression has not been sufficiently explored. In this study, we show that the lncRNA associated protein TOBF1 regulates the co-transcriptional alternative splicing of transcripts necessary for maintaining stem cell identity in mouse ES cells. Overlaying information derived from TOBF1 chromatin occupancy, the distribution of its pluripotency-associated OCT-SOX binding motifs, and transcripts undergoing differential expression and alternative splicing upon its disruption unmasked local nuclear territories where these distinct events converge, ultimately leading to the maintenance of mouse ES cell identity..
