Abstract: Agents binding modified antigen dependent peptides and use of same are provided. Accordingly, there is provided an agent capable of specifically binding an MHC presented peptide comprising a post translational modification (PTM), wherein the agent does not bind a peptide having the same amino acid sequence as said peptide but does not comprise said modification. Also provided are polynucleotides encoding the agent, cells expressing same and methods of use thereof. Also provided is a computer implemented method for generating a dataset of PTM on MHC bound peptides.

Abstract: Methods for the large scale identification of post-translational modification states of proteins and enzyme activities for carrying out post-translational modification reactions involve the analysis of functional extracts from fresh and frozen samples using protein arrays. The methods and kits of the present invention can be used to analyze and characterize compounds for their effects on post-translational modifications and their pathways. The methods and kits can also be used to diagnose and characterize a wide variety of diseases and medical conditions, including cancer, neurodegenerative diseases, immune diseases, infectious diseases, genetic diseases, metabolic conditions, and drug effects using cells or body fluids of a patient.
