Target Information

Background

Histones are subject to a variety of enzyme-catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitylation, and others. Among these modifications, lysine propionylation (Kpr) has emerged as a newly identified reversible modification that plays a crucial role in controlling protein activity. Structurally similar to lysine acetylation, lysine propionylation is prevalent in both prokaryotes and eukaryotes and has been identified in a wide range of proteins, including histones and non-histone substrates like p53. Recent research has unveiled the involvement of stoichiometric complexes comprising lysine acetyltransferase 6A (KAT6A), KAT6B, and bromodomain- and PHD finger-containing protein 1 (BRPF1) in the catalysis of histone H3 Lys23 propionylation (H3K23pr). Importantly, deficiencies in histone propionylation have been associated with developmental disorders and cancer.

ChIP

Sample: HeLa cells treated with 10 mM sodium propionate for 4 hours
Cross-linking conditions: no cross-linking
Amount of chromatin per IP: 5×106 cells
Amount of Ab per IP: 6 μg
Beads type and amount per IP: 50 μL of Protein A MagBeads
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 GAPDH CDS, RPL30 exon 3, LDHA, FOXO3a promoter, FOXO3a downstream, RAB20, TUBBP10, and LDHA promoter regions. The data are presented as enrichment of each sample relative to total amount of input chromatin at each amplicon.
