27074503 USP14 shows a marked preference for ubiquitin-cyclin B conjugates that carry more than one ubiquitin modification or chain
26817839 Cell surface ubiquitination precedes endocytosis, after which USP14 acts as an ubiquitin-binding protein that targets the ubiquitinated GABA B receptor to lysosomal degradation and promotes its deubiquitination.
26712154 Increased USP14 expression in patients with breast cancer was associated with a poorer prognosis.
26523394 Akt-mediated phosphorylation of USP14 at Ser432, which normally blocks its catalytic site in the inactive conformation, activates its deubiquitinating activity in vitro and in cells.
26397990 our findings suggested that USP14 is involved in the progression of hepatocellular carcinoma(HCC) and may be a useful therapeutic target in HCC
25429837 our findings suggest that USP14 is involved in the progression of epithelial ovarian cancer
24556800 MiR-4782-3p inhibited cell proliferation in NSCLC by targeting USP14, ZEB2 and XIAP.
24319254 b-AP15 is an inhibitor of deubiquitylating enzyme USP14 and UCHL5 induces apoptosis in multiple myeloma and overcomes bortezomib resistance.
23702845 Downregulation of USP14 expression arrested the cell cycle, which may be related to beta-catenin degradation.
23615914 overexpression of HA-USP14 increased the LPS-, TNFalpha-, or Escherichia coli-induced IL-8 release in human lung epithelial cells.
23291607 the decrease in proteolysis of proteasomal substrates during aging is independent of the increased USP14 activity and that the reciprocal regulation of USP14 and proteasomal catalytic activity may be necessary to maintain cellular ubiquitin homeostasis.
21627382 High Ubiquitin-specific protease 14 expression associated with intrahepatic cholangiocarcinoma cell differentiation.
20237496 Observational study of gene-disease association. (HuGE Navigator)
19726649 Data from transgenic mice define a critical role for Usp14 at mammalian synapses and suggest a requirement for local ubiquitin recycling by the proteasome to control the development and function of neuromuscular junctions.
19135427 These findings suggest that USP14 is a novel player in the unfolded protein response by serving as a physiological inhibitor of ER-associated degradation under the non-stressed condition.
17553343 USP14 were over-expressed in ovarian serous cystadenocarcinoma tissues, suggesting that the activity of ubiquitin-proteasome system is obviously enhanced in ovarian cancer.
17079671 Neuronal expression of full-length USP14 is able to restore the levels of monomeric ubiquitin in the brains of transgenic ataxia mice.
16465409 Results show the overall survival rate was worse in patients with a high USP14/TGT60 kD expression level and suggest that USP14/TGT60 kD also controls the fate of proteins that regulate tumor invasion and metastasis.
16211010 the catalytic cleft leading to the active site of USP14 is blocked by two surface loops. Binding by ubiquitin induces a significant conformational change thereby allowing access of the ubiquitin C-terminus to the active site.
