The enhancer module of Integrator controls cell identity and early neural fate commitment.

ABSTRACT: Lineage-specific transcription factors operate as master orchestrators of developmental processes by activating select cis-regulatory enhancers and proximal promoters. Direct DNA binding of transcription factors ultimately drives context-specific recruitment of the basal transcriptional machinery that comprises RNA polymerase II (RNAPII) and a host of polymerase-associated multiprotein complexes, including the metazoan-specific Integrator complex. Integrator is primarily known to modulate RNAPII processivity and to surveil RNA integrity across coding genes. Here we describe an enhancer module of Integrator that directs cell fate specification by promoting epigenetic changes and transcription factor binding at neural enhancers. Depletion of Integrator's INTS10 subunit upends neural traits a
