Target Information

Background

Histones are subject to a variety of enzyme catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitylation, etc. Crotonylation of lysine is a newly identified reversible modification controlling chromosome structure and gene transcription. The reversible lysine crotonylation has been well demonstrated in eukaryotic histones from worm to human. The unique structure and genomic localization of histone lysine crotonylation suggest that it is mechanistically and functionally different from histone lysine acetylation. Specifically, in both human somatic and mouse male germ cell genomes, histone crotonylation marks either active promoters or potential enhancers. Crotonylation of histone H3 at Lys18 may play a vital role in the epigenetic modulation, including chromatin remodeling and DNA transcriptional regulation.

ChIP

Sample: HeLa cells + crotonic acid (100 ng/ml, 18 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/G MagBeads
Description: Chromatin immunoprecipitations were performed with 6 μg of normal mouse IgG as a negative control. The immunoprecipitated DNA was quantified by real-time PCR using primers specific for the human GAPDH CDS, LDHA, FOXO3a-promoter, and FOXO3a-downstream regions. The data are presented as enrichment of each sample relative to total amount of input at each amplicon.
