Background
High-mobility group nucleosome-binding protein 1 (HMGN1), also known as HMG-14, is a member of the family of non-histone chromosomal proteins that play important roles in chromatin remodeling (1, 2). HMGN1 contains an N-terminal domain that interacts with nucleosomes and a C-terminal domain that assists chromatin unfolding (2, 3). Human HMGN1 shares 80% amino acid sequence identity with mouse and rat HMGN1. Alternative RNA processing generates a long isoform with a 45 amino acid insertion following Met1 (4). The trafficking of HMGN1 between the nucleus and cytoplasm is regulated by its serine phosphorylation at multiple sites (5, 6). In the nucleus, HMGN1 preferentially associates with sites of chromatin remodeling and gene transcription, allowing it to modulate the expression of a wide variety of genes (7, 8). It contributes to DNA damage repair by directly associating with and activating the double strand break sensor PARP-1 (9). HMGN1 is additionally one of several alarmins, proteins that are normally intracellular but are released following tissue damage or necrosis (1). In this setting, HMGN1 promotes dendritic cell maturation, recruitment to sites of inflammation, and production of Th1 inflammatory cytokines (10). These pro-inflammatory activities are dependent on the direct association of HMGN1 with the TLR4-MD2 complex on dendritic cells (10, 11).
