Proteome-wide analysis of elongating nascent polypeptide chains – peptide pulldown

ABSTRACT: Cellular global translation is often measured using ribosome profiling or quantitative mass spectrometry, but these methods do not provide direct information at the level of elongating nascent polypeptide chains (NPCs) and associated co-translational events. We combine quantitative proteomics, pulse labeling with puromycin, and stable isotope-labeled amino acids to analyze thousands of NPCs. Our approach enables global analyses of translational responses and co-translational modifications, providing a framework for dissecting co-translational regulations proteome-wide. The inputs (without IP) were analyzed in triplicates.
