Small Molecule Inhibitors of Protein Arginine Methyltransferases.
Athens, United States. In Expert Opin Investig Drugs, Feb 2016
Great efforts are seen in screening and designing potent and selective PRMT inhibitors, and a number of micromolar and submicromolar inhibitors have been obtained for key PRMT enzymes such as PRMT1, CARM1, and PRMT5.
Epigenetic regulation of pregnane X receptor activity.
College Station, United States. In Drug Metab Rev, 2013
Chromatin modifications are carried out, in part, through interaction with coregulator complexes, including steroid coactivators (SRCs), corepressors (NcoR/SMRT), hepatocyte nuclear factor 4 alpha, proliferator activated receptor γ coactivator 1 alpha and protein arginine methyltransferase 1. PXR can be modified by acetylation, phosphorylation and sumoylation, and the promoter of PXR can be methylated at the "CpG" island.
Ordered cooperative functions of PRMT1, p300, and CARM1 in transcriptional activation by p53.
New York City, United States. In Cell, 2004
In an extension of previous studies showing a role for acetyltransferase p300/CBP in p53 function, we have used systems reconstituted with recombinant chromatin templates and (co)activators to demonstrate (1) the additional involvement of protein arginine methyltransferases PRMT1 and CARM1 in p53 function; (2) both independent and ordered cooperative functions of p300, PRMT1, and CARM1; and (3) mechanisms that involve direct interactions with p53 and, most importantly, obligatory modifications of corresponding histone substrates.
