G Protein Mono-ubiquitination by the Rsp5 Ubiquitin Ligase [PDF]

, 2009
Emerging evidence suggests that ubiquitination serves as a protein trafficking signal in addition to its well characterized role in promoting protein degradation.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

Molecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Methods to investigate EGFR ubiquitination

, 2017
Ubiquitination of the epidermal growth factor receptor (EGFR) is an important intracellular signal that occurs upon EGF stimulation and controls EGFR trafficking at multiple steps, finally destining the receptor to lysosomal degradation. In this chapter,

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

The natural history of ubiquitin and ubiquitin-related domains [PDF]

Frontiers in Bioscience, 2012
The ubiquitin (Ub) system is centered on conjugation and deconjugation of Ub and Ub-like (Ubls) proteins by a system of ligases and peptidases, respectively. Ub/Ubls contain the beta-grasp fold, also found in numerous proteins with biochemically distinct roles unrelated to the conventional Ub-system. The beta-GF underwent an early radiation spawning at

Engineering IL‐4 resistant proinflammatory human myeloid cells for cancer immunotherapy

Molecular Oncology, EarlyView.
We developed a scalable workflow to generate proinflammatory human myeloid cells. CRISPR/Cas9‐edited CD34+ hematopoietic stem and progenitor cells were expanded and differentiated with M‐CSF. Deletion of STAT6 or STAT6/NFKB1 enhanced macrophage proinflammatory gene expression and cytokine secretion in the presence of IL‐4 while maintaining antibody ...

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

Molecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

Deciphering non-canonical ubiquitin signaling: biology and methodology

Frontiers in Molecular Biosciences
Ubiquitination is a dynamic post-translational modification that regulates virtually all cellular processes by modulating function, localization, interactions and turnover of thousands of substrates.
