Histone Deimination Antagonizes Arginine Methylation
Methylation of arginine residues within histone H3 has been linked to active transcription. This modification appears on the estrogen-regulated pS2 promoter when the CARM1 methyltransferase is recruited during transcriptional activation. Here we describe a process, deimination, that converts histone arginine to citrulline and antagonizes arginine methylation. We show that peptidyl arginine deim...
متن کاملHistone arginine methylation and its dynamic regulation.
Methylation of histones by protein arginine methyltransferases (PRMTs) is increasingly being found to play an important and dynamic role in gene regulation. In mammals, PRMT1- and CARM1-catalyzed histone asymmetric dimethyl-arginine is involved in gene activation while PRMT5-catalyzed histone symmetric dimethyl-arginine is associated with gene repression. Insight into mechanisms by which histon...
متن کاملHuman PAD4 regulates histone arginine methylation levels via demethylimination.
Methylation of arginine (Arg) and lysine residues in histones has been correlated with epigenetic forms of gene regulation. Although histone methyltransferases are known, enzymes that demethylate histones have not been identified. Here, we demonstrate that human peptidylarginine deiminase 4 (PAD4) regulates histone Arg methylation by converting methyl-Arg to citrulline and releasing methylamine...
متن کاملHistone arginine methylation in cocaine action in the nucleus accumbens.
Repeated cocaine exposure regulates transcriptional regulation within the nucleus accumbens (NAc), and epigenetic mechanisms-such as histone acetylation and methylation on Lys residues-have been linked to these lasting actions of cocaine. In contrast to Lys methylation, the role of histone Arg (R) methylation remains underexplored in addiction models. Here we show that protein-R-methyltransfera...
متن کاملCross-talk among epigenetic modifications: lessons from histone arginine methylation.
Epigenetic modifications, including those occurring on DNA and on histone proteins, control gene expression by establishing and maintaining different chromatin states. In recent years, it has become apparent that epigenetic modifications do not function alone, but work together in various combinations, and cross-regulate each other in a manner that diversifies their functional states. Arginine ...
