Nuclear extract of HeLa cells (20 µg) tested by Western blot using Histone H4R3me2a (asymmetric) antibody (pAb) at a dilution of 1:500.

Histone H4R3me2a (asymmetric) antibody (pAb) tested by dot blot analysis.

Histone H4R3me2a (asymmetric) antibody (pAb)tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of Histone H4 dimethyl Arg3 asymmetric antibody for dimethyl-arginine 3 of histone H4. Peptides corresponding to the immunogen and related peptides were spotted onto PVDF and probed with Histone H4 dimethyl Arg3 asymmetric antibody at 1:2,500. The amount of peptide (picomoles) spotted is indicated next to each row.

Lane 1: unmodified H4 peptide aa 1-10.
Lane 2: H4 monomethyl-Arg3 peptide.
Lane 3: dimethyl-Arg3(asymmetric) H4 peptide.
Lane 4: dimethyl-Arg3 (symmetric) H4 peptide.

Histone H4R3me2a antibody (pAb) specificity tested by peptide array analysis.

Histone H4R3me2a (asymmetric) antibody (pAb) specificity tested by peptide array analysis.
Peptide array analysis was used to confirm the specificity of this antibody for its intended modification. Histone H4R3me2a antibody was applied at a dilution of 1:20,000 to Active Motif's MODified™ Histone Peptide Array (Catalog No. 13001). The arrays were scanned with ArrayAnalysis Software 16 and the results plotted. Specificity data is shown for the most reactive peptides and those related to the immunogen.


Histone H4 is one of the core components of the nucleosome, the basic building block of chromatin. Histones are subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; these modifications play a major role in regulating gene expression. The methylation of histones can occur on two different residues: arginine or lysine.

Asymmetric dimethylation of histone H4 at arginine 3 (Arg3), catalyzed by the PRMT methyltransferases, is associated with transcriptional activation by nuclear hormone receptors. Arg3 methylation has been reported to facilitate the subsequent acetylation of histone H4 by the acetyltransferase p300. Histone H4 dimethyl Arg3 asymmetric methylation (H4R2me2a) is catalyzed by PRMT1 and PRMT6.
