Anti-methyl-Histone H3 (Lys27)

Histone H3 K27 methyl Antibody was purified from monospecific antiserum by protein A chromatography. This antibody recognizes the Me1, Me2 and Me3 of Lys27 for human Histone H3. A BLAST analysis was used to suggest cross-reactivity with Human, mouse, rat, and C. elegans based on 100% sequence homology. Cross-reactivity with Histone H3 [methyl Lys27] from other sources has not been determined. Protein function: Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. [The UniProt Consortium]
