In this study we characterize and investigate the effect of the loss of Ku70 protein in a conditional Ku70 knockout TREx-293 cell system. Loss of Ku70 protein levels was directly correlated with a loss of cell viability, supporting the observation that Ku performs an essential role in human cells. I...

The human CTLH complex is a newly discovered multi-subunit E3 ligase. At present, only a few of its ubiquitination targets are known. Here, we use proteomic techniques in RanBPM-depleted HeLa cells to identify ubiquitination substrates of the CTLH complex. First, global proteomics determined protein...

NQO2/QR2 is related to NQO1, a known quionine reductase that functions in detoxicification for cells. NQO2, however, uses a distinct co-substate with uncertain availability in cells and as a result the functions of NQO2 are poorly understood. Here, to gain insight into potential pathways regulated b...

The CTLH complex is a multi-subunit ubiquitin ligase complex that recognizes substrates with Pro/N-degrons via substrate receptor GID4. Recently, focus has turned to the complex as a potential mediator of targeted protein degradation, but the role GID4-mediated substrate ubiquitylation and proteasom...
