Based on limited published evidence, H2BC11 is a histone protein with dual functions in chr6 structure and antimicrobial immunity. As a structural constituent of chr6, it participates in nucleosome assembly and chr6 organization [GO annotations]. H2BC11 exhibits broad antibacterial activity and may contribute to the antimicrobial barrier of the colonic epithelium and bactericidal activity of amniotic fluid [UniProt Function]. It is involved in innate immune responses, including antibacterial humoral responses against both Gram-negative and Gram-positive bacteria, with demonstrated lipopolysaccharide binding capacity [GO annotations]. Recent studies identified H2BC11 as a survival-related gene in pancreatic adenocarcinoma 1 and a potential drug target for lung cancer treatment, showing notable binding interaction with Valproic acid 2.
