ProteomicsMass spectrometry analysis of polyubiquitin chain branching on PCNA by ubiquitin-clipping using BpJOS
A mass spectrometry analysis was performed to study the impact of VCP on polyubiquitin chain branching on PCNA, using ubiquitin-clippase BpJOS.

ProteomicsTrans-branching of polyubiquitin chains orchestrates the DNA replication stress response
Polyubiquitin chain geometry dictates functional consequences of ubiquitylation. Although branched polyubiquitin chains are abundant in cells, little is known about their functions. Here we show that branching on the DNA replication factor PCNA, mediated by the ubiquitin-conjugating enzyme UBE2K and...
