Robust unsupervised deconvolution of linear motifs characterizes 68 protein modifications at proteome scale

Abstract The local sequence context is the most fundamental feature determining the post-translational modification (PTM) of proteins. Recent technological improvements allow for the detection of new and less prevalent modifications. We found that established state-of-the-art algorithms for the dete...
