Résumé
Ubiquitination is a prevalent post-translational modification that controls a multitude of important biological processes. Due to the low abundance of ubiquitinated proteins, highly efficient separation and enrichment approaches are required for ubiquitinome analysis. In this work, we disclose the region-specific interactions between the hydrophobic patch of ubiquitin and polydopamine. Taking advantage of this inherent binding property, we have constructed surface-imprinted magnetic nanoparticles (NPs) for ubiquitin by sequential dopamine polymerization and surface PEGylation. The obtained molecularly imprinted polymer (MIP) NPs showed a binding constant of 2.6 × 10
