Sequential Peptide Immunopurification Methodology to Monitor the Crosstalk between SUMOylation and Ubiquitylation


ABSTRACT: We describe a method that permits the identification of proteins that are modified by both SUMOylation and ubiquitylation to better understand the role of this crosstalk. The procedure requires 3 days when starting from cell pellets and can yield more than 8000 SUMO sites and 3500 ubiquitin sites from 16 mg of cell extract.

Ubiquitin and ubiquitin-like modifiers (UBLs) such as small ubiquitin-like modifier (SUMO) can act as antagonists to one another by competing to occupy similar residues in the proteome. In addition, SUMO and ubiquitin can be coupled to each other at key lysine residues to form highly branched protein networks. The interplay between these modifications governs important biological processes such as double-strand break repair and meiotic recombination. We recently developed an approach that permit  ...[more]
