Target Information

Background

Histones are subjected to a variety of enzyme catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitylation, etc. 2-hydroxyisobutyrylation of lysine is a newly identified reversible modification controlling chromosome structure and gene transcription. The reversible lysine 2-hydroxyisobutyrylation has been well demonstrated in eukaryotic histones from worm to human. The unique structure and genomic localization of histone lysine 2-hydroxyisobutyrylation suggest that it is mechanistically and functionally different from histone lysine acetylation. Specifically, in both human somatic and mouse male germ cell genomes, histone 2-hydroxyisobutyrylation marks either active promoters or potential enhancers.

ChIP

Cell type: Hela + sodium butyrate (30 mM, 4 hr)
Cross-linking conditions: No cross-linking
Amount of chromatin per IP: 5×106 cells
Amount of Ab per IP: 4 μg, 12 μg
Beads type and amount per IP: 50 μl of Protein A/G MagBeads
Description: Chromatin immunoprecipitations were performed with 1 μg of normal mouse IgG as a negative control. Real time
quantitative PCR was performed on immunoprecipitated DNA using primers specific for the human
GAPDH CDS region, LDHA, FOXO3a-promoter, FOXO3a-downstream and RAB20. Data are
presented as enrichment of each sample relative to total amount of input chromatin at each amplicon.
