Protein methylation has recently emerged as one of the most exciting areas of
study on posttranslational modification. A large family of protein
methyltransferases has been identified and their structural properties have been
characterized. These studies have provided novel insights into how methylation
regulates a variety of biological functions including DNA and RNA metabolism,
protein synthesis and signal transduction. Methylation also plays important
roles in aging. This volume is intended to capture these recent developments
concerning protein methyltransferases.
