Tryptic peptide sequence with PTM can be searched via PATS within this Bioplex (HEK cell interactome) data (Huttlin, EL et al.). This data contains more than 12,000 hours of AP-MS from more than 6,000 bait proteins. To search the Hela cell interactome data (Hein, MY et al.), please click here Hela cell interactome. Please enter your tryptic peptide of interest. If you want to search for a protein/long peptide, please use PeptideMass to digest it first and then search for the tryptic peptides. For more advanced search, please see PATS source codes for more details.
