Abstract:Mass spectrometry (MS) has become a central technique to identify and quantify post-translational modifications (PTMs), overcoming limitations of antibody-based methods. Histones get dynamically modified by diverse chemical groups, particularly on their numerous lysine residues, to fine-tune all DNA-templated processes. Reliable identification of histone PTMs remains challenging and still requires manual data curation. This study focused on the Lys27-Arg40 stretch of histone H3, considered four sequence varian… Show more
