HMGN1 and HMGN2 are recruited to acetylated and histone variant H2A.Z-containing nucleosomes to regulate chromatin state and transcription
Ontology highlight
ABSTRACT: The High Mobility Group Nucleosome-binding (HMGN) proteins are small abundant nuclear proteins that directly bind nucleosomes and constitute a major component of chromatin. HMGN proteins specifically localize to enhancers and actively transcribed genes across the genome, however the roles of HMGN proteins in regulating chromatin structure and transcription remain poorly understood. To investigate the function of HMGN proteins on chromatin, we engineered mouse embryonic stem cells (mESCs) lacking HMGN1 and/or HMGN2 (Hmgn1-/- mESCs, Hmgn2-/- mESCs, and Hmgn1-/-Hmgn2-/- mESCs) and performed mass spectrometry-based quantification of a panel of histone residue states to quantify the levels of specific histone modifications in WT and Hmgn1-/-Hmgn2-/- mESCs.
