TULIP2: An Improved Method for the Identification of Ubiquitin E3-Specific Targets

Frontiers in Chemistry, 2019
Protein modification by Ubiquitin or Ubiquitin-like modifiers is mediated by an enzyme cascade composed of E1, E2, and E3 enzymes. E1s, or ubiquitin-activating enzymes, perform ubiquitin activation. Next, ubiquitin is transferred to ubiquitin-conjugating

A Novel Peptide-Based SILAC Method to Identify the Posttranslational Modifications Provides Evidence for Unconventional Ubiquitination in the ER-Associated Degradation Pathway. [PDF]

, 2013
The endoplasmic reticulum-associated degradation (ERAD) pathway is responsible for disposing misfolded proteins from the endoplasmic reticulum by inducing their ubiquitination and degradation.

USP10 Inhibits Ferroptosis via Deubiquinating POLR2A in Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study identifies USP10 as a novel deubiquitinase that antagonizes ferroptosis in head and neck squamous cell carcinoma (HNSCC). Mechanistically, USP10 directly stabilizes POLR2A protein through post‐translational deubiquitination, enabling POLR2A‐mediated transcriptional activation of SLC7A11, a key ferroptosis inhibitor.

Expression and Effect of Inhibition of the Ubiquitin-Conjugating Enzyme E2C on Esophageal Adenocarcinoma

Neoplasia: An International Journal for Oncology Research, 2006
Ubiquitin-dependent proteolysis of cyclins plays a critical role in cell cycle progression and tumorigenesis. We examined the expression of ubiquitin-conjugating enzyme E2C (UBE2C) during progression from Barrett's metaplasia to esophageal adenocarcinoma

Ubiquitin-Conjugating Enzyme UBE2C Is Highly Expressed in Breast Microcalcification Lesions

PLoS ONE, 2014
Ubiquitin-conjugating enzyme 2C (UBE2C) contributes to ubiquitin-mediated proteasome degradation of cell cycle progression in breast cancer. Microcalcification (MC) is the most common mammographic feature of early breast cancer.

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

Advanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

In vitro Ubiquitin Dimer Formation Assay

Bio-Protocol, 2017
The process of protein ubiquitination typically consists of three sequential steps to add an ubiquitin (Ub) or Ub chain to a substrate protein, requiring three different enzymes, ubiquitin activating enzyme (E1), ubiquitin conjugating enzyme (E2), and ...

Covalent protein modification with ISG15 via a conserved cysteine in the hinge region. [PDF]

PLoS ONE, 2012
The ubiquitin-like protein ISG15 (interferon-stimulated gene of 15 kDa) is strongly induced by type I interferons and displays antiviral activity. As other ubiquitin-like proteins (Ubls), ISG15 is post-translationally conjugated to substrate proteins by ...

The analysis of pendolino (peo) mutants reveals differences in the fusigenic potential among Drosophila telomeres [PDF]

, 2015
Drosophila telomeres are sequence-independent structures that are maintained by transposition to chromosome ends of three specialized retroelements (HeT-A, TART and TAHRE; collectively designated as HTT) rather than telomerase activity. Fly telomeres are

H3K36me3‐Guided m6A Modification of Oncogenic L1CAM‐AS1 Drives Macrophage Polarization and Immunotherapy Resistance in Hepatocellular Carcinoma

Advanced Science, EarlyView.
L1CAM‐AS1 is identified as a novel H3K36me3‐guided, m6A‐modified long noncoding RNA (lncRNA) in hepatocellular carcinoma (HCC) cells. L1CAM‐AS1 stabilizes RAN protein, enhances M2 macrophages‐released CCL5‐induced nuclear import of RELA, activates the NF‐κB signaling, up‐regulates CCL2 expression and secretion from HCC cells, and enhances M2 ...
