Natural genetic variation perturbs collaborative transcription factor binding required for enhancer selection and function


ABSTRACT: Natural genetic variation between two mouse strains was used as a natural mutagenesis screen to test various aspects of the proposed model for enhancer selection and function. Chromatin marks H3K4me2, H3K27Ac, and transcription factors PU.1, C/EBPa, and p65 were assessed by ChIP-Seq and GRO-Seq and RNA-Seq were used to measure gene expression in C57BL6/J and BALBc/J inbred mouse strains

The mechanisms by which genetic variation affects transcription regulation and phenotypes at the nucleotide level are incompletely understood. Here we use natural genetic variation as an in vivo mutagenesis screen to assess the genome-wide effects of sequence variation on lineage-determining and signal-specific transcription factor binding, epigenomics and transcriptional outcomes in primary macrophages from different mouse strains. We find substantial genetic evidence to support the concept tha  ...[more]
