Target Information

Background

Histones, fundamental proteins involved in chromatin structure and gene regulation, are subject to a wide array of enzyme-catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitination, and numerous others. Histone L-lactylation is a recently discovered post-translational modification that is induced by lactate, a metabolite produced during glycolysis. Regulated by glucose metabolic dynamics and lactate levels within the cellular microenvironment, histone lactylation is implicated in various biological processes, including inflammation, fibrosis, differentiation, and cancer progression. The introduction of lysine L-lactylation is mediated by the acetyltransferase p300, while the removal of lactylation marks from histones has been attributed to Class I histone deacetylases (HDAC 1-3). Notably, Sirtuin 3 (SIRT3) has been reported as an eraser of H4K16 lactylation (H4K16la).

Description: Chromatin immunoprecipitations were performed with 6 μg of normal rabbit IgG as a negative control. The immunoprecipitated DNA was quantified by real-time PCR using primers specific for the human RPL30 Exon 3 and TUBBP10 regions. The data are presented as enrichment of each sample relative to total amount of input at each amplicon.
