Description générale
Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming a nucleosome. Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. These modifications can alter local chromatin architecture, or recruit trans-acting factors that recognize specific histone modifications (the "histone code" hypothesis). The modifications occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Histone H3 is methylated at Lys27 by EZH2, and and overexpression of EZH2 has been associated with both breast and prostate cancers. Methylation of H3K27 is involved in X chroosome inactivation, imprinting, circadian rhythms, and stem cell maintenance. H3K27me2 is a marker of classical heterochromatin.
Spécificité
Broad species cross-reactivity expected, based on sequence identity in most species.
Histone H3 dimethylated on Lys27. An unidentified doublet sometimes appears by Western blotting in some lysates at ~35 kDa.
Immunogène
Peptide containing the sequence (ARme2KSA) in which me2 corresponds to dimethyl lysine at residue 27 of human histone H3.
Application
Anti-dimethyl-Histone H3 (Lys27) Antibody, clone 614M is a rabbit monoclonal antibody for detection of dimethyl-Histone H3 (Lys27) also known as H3K27me2, Histone H3 (di methyl K27) & has been validated in WB, PIA.
Western Blot Analysis:
1:1000-1:5000 dilutions of a previous lot of this clone detected dimethyl-Histone H3 in acid extracted proteins from HeLa cells, but did not detect unmethylated recombinant Histone H3 (Catalog # 14-494).
Peptide Inhibition:
0.5-2 µM of histone H3 peptides containing dimethyl-Lys27 abolished detection of histone H3 by anti-dimethyl-Histone H3 (Lys27), clone 614M (1:1000 dilution) in immunoblots of acid extracted proteins from HeLa cells.

The p160 family of coactivators, SRC-1, GRIP1/TIF2, and p/CIP, mediate transcriptional activation by nuclear hormone receptors. Coactivator-associated arginine methyltransferase 1 (CARM1), a previously unidentified protein that binds to the carboxyl-terminal region of p160 coactivators, enhanced transcriptional activation by nuclear receptors
Establishment of histone h3 methylation on the inactive X chromosome requires transient recruitment of Eed-Enx1 polycomb group complexes.

Epigenetic regulators, when genomically altered, may become driver oncogenes that mediate otherwise unexplained pro-oncogenic changes lacking a clear genetic stimulus, such as activation of the WNT/β-catenin pathway in melanoma. This study identifies previously unrecognized recurrent activating mutations in the G9a
