Tryptic peptide sequence with PTM can be searched via PATS within this HeLa interactome data (Hein, MY et al.) This data contains more than 8,000 hours of AP-MS from more than 1,300 bait proteins. Please enter your tryptic peptide of interest. To search the HEK cell interactome data (Bioplex) (Huttlin, EL et al.), please click here HEK cell interactome. 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.
