Non-specific recognition of histone modifications by H3K9bhb antibody.

ABSTRACT: Ketone bodies are short-chain fatty acids produced in the liver during periods of limited glucose availability that provide an alternative energy source for the brain, heart, and skeletal muscle. Beyond this metabolic role, β-hydroxybutyrate (BHB), is gaining recognition as a signaling molecule. Lysine β-hydroxybutyrylation (Kbhb) is a newly discovered post-translational modification in which BHB is covalently attached to lysine ε-amino groups. This protein adduct is metabolically sensitive, dependent on BHB concentration, and found on proteins in multiple intracellular compartments. Therefore, Kbhb is hypothesized to be an important component of ketone body-regulated physiology. Kbhb on histones is proposed to be an epigenetic regulator, which links metabolic alterations to gene expressio
