Protein methyltransferase inhibitors as precision cancer therapeutics: a decade of discovery.


ABSTRACT: The protein methyltransferases (PMTs) represent a large class of enzymes that catalyse the methylation of side chain nitrogen atoms of the amino acids lysine or arginine at specific locations along the primary sequence of target proteins. These enzymes play a key role in the spatio-temporal control of gene transcription by performing site-specific methylation of lysine or arginine residues within the histone proteins of chromatin, thus effecting chromatin conformational changes that activate or repress gene transcription. Over the past decade, it has become clear that the dysregulated activity of some PMTs plays an oncogenic role in a number of human cancers. Here we review research of the past decade that has identified specific PMTs as oncogenic drivers of cancers and progress toward the discovery and development of selective, small molecule inhibitors of these enzymes as precision cancer therapeutics.This article is part of a discussion meeting issue 'Frontiers in epigenetic chemical biology'.
