TCellXTalk facilitates the detection of co-modified peptides for the study of protein post-translational modification cross-talk in T cells

PTMselect: optimization of protein modifications discovery by mass spectrometry

Discovery of protein modification sites relies on protein digestion by proteases and mass spectrometry (MS) identification of the modified peptides. Depending on proteases used and target protein sequence, this method yields highly variable coverage of modification sites. We introduce PTMselect, a digestion-simulating software which tailors the optimal set of proteases for discovery of global or targeted modification from any single or multiple proteins.
