title: Specificity of protein lysine methyltransferases and methods for detection of lysine methylation of non-histone proteins.
abstract: Post translational modification of histone proteins including lysine methylation is an important epigenetic mark, essential for gene regulation and development. Recently, several examples of lysine methylation of non-histone proteins have been discovered suggesting that this is a common post-translational modification for regulation of protein activity. Here, we review assays for the detection of protein methylation based on mass spectrometry, radiolabel and immunological approaches using protein and peptide substrates including application of SPOT peptide arrays. Candidates for new methylation targets of protein methyltransferases can be predicted using the specificity of the enzyme and protein interaction data.
