Ubiquitin-dependent and -independent proteasomal protein degradation.

open access: yes, 2023
A. UPS protein degradation resulting from (1) ubiquitin system targeting followed by (2) proteasomal protein degradation. B. Proteins with ubiquitin-independent degrons are directly bound and degraded by the proteasome without ubiquitin system targeting.

The Ubiquitin Proteasome System Is a Key Regulator of Pluripotent Stem Cell Survival and Motor Neuron Differentiation

open access: yesCells, 2019
The ubiquitin proteasome system (UPS) plays an important role in regulating numerous cellular processes, and a dysfunctional UPS is thought to contribute to motor neuron disease.

Resolving the Complexity of Ubiquitin Networks

open access: yesFrontiers in Molecular Biosciences, 2020
Ubiquitination regulates nearly all cellular processes by coordinated activity of ubiquitin writers (E1, E2, and E3 enzymes), erasers (deubiquitinating enzymes) and readers (proteins that recognize ubiquitinated proteins by their ubiquitin-binding ...

Ubiquitination of GPCRs [PDF]

open access: yes, 2011
In this chapter, we describe a method for detecting the ubiquitination status of G protein-coupled receptors (GPCRs). This involves co-expression of a GPCR with an epitope-tagged ubiquitin construct in a -heterologous mammalian expression system. Stimulus-dependent modification of the GPCR by -ubiquitin is detected by immunoprecipitation and subsequent

The molecular basis of CRL4 ubiquitin ligase architecture, targeting and regulation [PDF]

open access: yes, 2013
Members of the CUL4-RBX1-DDB1 (CRL4) E3 ubiquitin ligase family regulate multiple cellular processes including development, transcription, and DNA repair.

Ubiquitin-dependent and independent pathways of mitophagy.

open access: yes, 2023
(A) Canonical ubiquitin-dependent mitophagy. In basal conditions, the PINK1 serine/threonine protein kinase precursor is targeted to healthy mitochondria thanks to its MTS, allowing its interaction with the TOMM complex and its import from the OMM to the

The Ubiquitin Moiety of Ubi1 Is Required for Productive Expression of Ribosomal Protein eL40 in Saccharomyces cerevisiae

open access: yesCells, 2019
Ubiquitin is a highly conserved small eukaryotic protein. It is generated by proteolytic cleavage of precursor proteins in which it is fused either to itself, constituting a polyubiquitin precursor of head-to-tail monomers, or as a single N-terminal ...

The Positive Correlations between the Expression of Histopathological Ubiquitin-Conjugating Enzyme 2O Staining and Prostate Cancer Advancement

open access: yesPharmaceuticals, 2021
Background: The mTOR signaling pathway is inactivated by AMPK’s tumor-suppressing function. It is recognized that ubiquitin conjugating enzyme 2O (UBE2O), which directly targets AMPK for ubiquitination and degradation, is intensified in human cancers ...

Regulation of ubiquitin and ubiquitin‐like modifiers by phosphorylation [PDF]

open access: yesThe FEBS Journal, 2021
The regulatory influence of ubiquitin is vast, encompassing all cellular processes, by virtue of its central roles in protein degradation, membrane trafficking, and cell signaling. But how does ubiquitin, a 76 amino acid peptide, carry out such diverse, complex functions in eukaryotic cells? Part of the answer is rooted in the high degree of complexity

The fanconi anemia DNA repair pathway is regulated by an interaction between ubiquitin and the E2-like fold domain of FANCL [PDF]

open access: yes, 2015
The Fanconi Anemia (FA) DNA repair pathway is essential for the recognition and repair of DNA interstrand crosslinks (ICL). Inefficient repair of these ICL can lead to leukemia and bone marrow failure.
