To date, proteomics efforts have primarily been confined to recording variations in protein level rather than activity. Glycosylation mainly refers to the enzymatic process that attaches glycans to proteins, lipids, or other organic molecules. There are vastly too many different possible conformations for a protein to fold by a random search. So far, there have been no reports attempting to more comprehensively profile the landscape of prostate cancer-associated antibodies. Correct peptide might be missing from database!
