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. This antibody can simultaneously identify histone H3 at Lys15, 16 and 20.

Comment: The ChIP was performed with 6 μg of normal Rabbit IgG as a negative control. Real time quantitative PCR was performed on immunoprecipitated DNA using primers specific for the human GAPDH CDS region, RPL30, LDHA CDS region, FOXO3a-promoter, FOXO3a-downstream, RAB20 and TuBBP10. Data are presented as enrichment of each sample relative to total amount of input chromatin at each amplicon.
