Activity-based ubiquitin-specific protease (USP) profiling of virus-infected and malignant human cells
Open accessAbstract
The family of ubiquitin (Ub)-specific proteases (USP) removes Ub from Ub conjugates and regulates a variety of cellular processes. The human genome contains many putative USP-encoding genes, but little is known about USP tissue distribution, pattern of expression, activity, and substrate specificity. We have used a chemistry-based functional proteomics approach to identify active USPs in normal, virus-infected, and tumor-derived human cells. Depending on tissue origin and stage of activation/differentiation, different USP activity profiles were revealed. The activity of specific USPs, including USP5, -7, -9, -13, -15, and -22, was up-regulated by mitogen activation or virus infection in normal T and B lymphocytes. UCH-L1 was highly expressed in tumor cell lines of epithelial and hematopoietic cell origin but was not detected in freshly isolated and mitogen-activated cells. Up-regulation of this USP was a late event in the establishment of Epstein–Barr virus-immortalized lymphoblastoid cell lines and correlated with enhanced proliferation, suggesting a possible role in growth transformation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
