Functional Diversity and Structural Disorder in the Human Ubiquitination Pathway

open access: yes, 2013
The ubiquitin-proteasome system plays a central role in cellular regulation and protein quality control (PQC). The system is built as a pyramid of increasing complexity, with two E1 (ubiquitin activating), few dozen E2 (ubiquitin conjugating) and several

UBE2QL1 is Disrupted by a Constitutional Translocation Associated with Renal Tumor Predisposition and is a Novel Candidate Renal Tumor Suppressor Gene [PDF]

open access: yes, 2013
Investigation of rare familial forms of renal cell carcinoma (RCC) has led to the identification of genes such as VHL and MET that are also implicated in the pathogenesis of sporadic RCC. In order to identify a novel candidate renal tumor suppressor gene,

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

open access: yesMolecular 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.

Linear ubiquitin chains: enzymes, mechanisms and biology [PDF]

open access: yesOpen Biology, 2017
Ubiquitination is a versatile post-translational modification that regulates a multitude of cellular processes. Its versatility is based on the ability of ubiquitin to form multiple types of polyubiquitin chains, which are recognized by specific ...

In vitro Auto- and Substrate-Ubiquitination Assays

open access: yesBio-Protocol, 2022
The precise regulation of the homeostasis of the cellular proteome is critical for the appropriate growth and development of plants. It also allows the plants to respond to various environmental stresses, by modulating their biochemical and ...

Crystal structure of UBA2ufd-Ubc9: insights into E1-E2 interactions in sumo pathways [PDF]

open access: yes, 2010
Canonical ubiquitin-like proteins (UBLs) such as ubiquitin, Sumo, NEDD8, and ISG15 are ligated to targets by E1-E2-E3 multienzyme cascades. The Sumo cascade, conserved among all eukaryotes, regulates numerous biological processes including protein ...

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

open access: yesMolecular 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

TRIM5α as an E3 ubiquitin ligase

open access: yesThe FASEB Journal, 2009
Human immunodeficiency virus type1 (HIV‐1) efficiently infects susceptible cells and causes acquired immunodeficiency syndrome (AIDS) in humans. Although HIV can also enter the cells of Old World monkeys, it encounters a block before reverse transcription.

Overexpression of a soybean ariadne-like ubiquitin ligase gene GmARI1 enhances aluminum tolerance in Arabidopsis. [PDF]

open access: yesPLoS ONE, 2014
Ariadne (ARI) subfamily of RBR (Ring Between Ring fingers) proteins have been found as a group of putative E3 ubiquitin ligases containing RING (Really Interesting New Gene) finger domains in fruitfly, mouse, human and Arabidopsis.

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

open access: yes, 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 ...
