Novel RING E3 Ubiquitin Ligases in Breast Cancer

Neoplasia: An International Journal for Oncology Research, 2006
Defects in ubiquitin E3 ligases are implicated in the pathogenesis of several human diseases, including cancer, because of their central role in the control of diverse signaling pathways.

ITCH E3 ligase in ATM network

Oncoscience, 2014
Ataxia Telangiectasia Mutated (ATM) kinase is a central regulator of the DNA damage response and its loss of function leads to the development of Ataxia Telangiectasia, a rare genetic disorder characterized by several features among which cerebellar neuron degeneration which causes ataxia, telangiectasia, immune system abnormalities, higher ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

The hGID GID4 E3 ubiquitin ligase complex targets ARHGAP11A to regulate cell migration

Life Science Alliance
This study shows that the hGID GID4 E3 ligase controls cell migration by ubiquitinating ARHGAP11A for degradation, thereby regulating RhoA activity.

Unbiased identification of substrates for the Epac1-inducible E3 ubiquitin ligase component SOCS-3

, 2012
The anti-inflammatory effects of the prototypical second messenger cAMP have been extensively documented in multiple cell types. One mechanism by which these effects are achieved is via Epac1 (exchange protein directly activated by cAMP 1)-dependent ...

Trim25 is an RNA-specific activator of Lin28a/TuT4-mediated uridylation [PDF]

, 2014
RNA binding proteins have thousands of cellular RNA targets and often exhibit opposite or passive molecular functions. Lin28a is a conserved RNA binding protein involved in pluripotency and tumorigenesis that was previously shown to trigger TuT4-mediated

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Classification of barley U-box E3 ligases and their expression patterns in response to drought and pathogen stresses

BMC Genomics, 2019
Background Controlled turnover of proteins as mediated by the ubiquitin proteasome system (UPS) is an important element in plant defense against environmental and pathogen stresses.
