HIST1H2BC is a core histone H2B variant involved in nucleosome assembly, DNA repair, and transcriptional regulation. β-hydroxybutyrylation (Kbhb) is a histone modification induced by β-hydroxybutyrate (BHB), a ketone body produced during fasting or ketogenic states. Kbhb modulates chromatin structure and gene expression, influencing:
Metabolic Regulation: BHB levels directly correlate with histone Kbhb, linking cellular metabolism to epigenetic states.
Disease Pathways: Altered Kbhb levels are implicated in cancer, sarcopenia, and metabolic disorders.
Key Research Applications
Investigating epigenetic changes in cancer and aging.
Studying mitochondrial dysfunction and muscle atrophy (sarcopenia).
Validating specificity of Kbhb antibodies in cell models (e.g., HEK293, C2C12 myotubes).
Key Experimental Data
Study Model
Findings
Citation
HEK293 Cells
BHB treatment increased H3K9bhb and H4K8bhb, but HIST1H2BC-K11bhb showed distinct regulation.
C2C12 Myotubes
β-hydroxybutyrate (1 mM) reversed TNF-α-induced sarcopenia by enhancing mitochondrial function via Kbhb.
iMEFs
Non-specific recognition observed with some Kbhb antibodies under butyrate or TSA treatment.
Limitations and Considerations
Cross-Reactivity Risks: Antibodies targeting Kbhb may recognize other acylation modifications (e.g., butyrylation) in certain conditions.
Species Restriction: Limited to human samples, requiring validation for cross-species studies.

This antibody targets β-hydroxybutyryl-HIST1H2BC (K11), a core component of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to cellular machinery that utilizes DNA as a template. Consequently, histones play a crucial role in transcription regulation, DNA repair, DNA replication, and chromosomal stability. DNA accessibility is regulated through a complex set of post-translational modifications of histones, often referred to as the histone code, and nucleosome remodeling. Additionally, β-hydroxybutyryl-HIST1H2BC (K11) exhibits broad antibacterial activity. It may contribute to the formation of the functional antimicrobial barrier of the colonic epithelium and the bactericidal activity of amniotic fluid.
