Multiple UBX proteins reduce the ubiquitin threshold of the mammalian p97-UFD1-NPL4 unfoldase

open access: yeseLife, 2022
The p97/Cdc48 ATPase and its ubiquitin receptors Ufd1-Npl4 are essential to unfold ubiquitylated proteins in many areas of eukaryotic cell biology.

Ubiquitylation of DNA polymerase λ

open access: yesFEBS Letters, 2011
DNA polymerase (pol) λ, one of the 15 cellular pols, belongs to the X family. It is a small 575 amino‐acid protein containing a polymerase, a dRP‐lyase, a proline/serine rich and a BRCT domain. Pol λ shows various enzymatic activities including DNA polymerization, terminal transferase and dRP‐lyase.

Determination of VPS34/PIK3C3 Activity in vitro Utilising 32P-γATP

open access: yesBio-Protocol, 2016
VPS34 is the only class III phosphatidylinositol-3-kinase (PI3K) in mammalian cells and produces the vast majority of cellular phosphatidylinositol-3-phosphate [PI(3)P].

Disorders of ubiquitylation: unchained inflammation

open access: yesNature Reviews Rheumatology, 2022
Ubiquitylation is an essential post-translational modification that regulates intracellular signalling networks by triggering proteasomal substrate degradation, changing the activity of substrates or mediating changes in proteins that interact with substrates.

Profiling ubiquitin signalling with UBIMAX reveals DNA damage- and SCFβ-Trcp1-dependent ubiquitylation of the actin-organizing protein Dbn1

open access: yesNature Communications, 2023
Ubiquitin widely modifies proteins, thereby regulating most cellular functions. The complexity of ubiquitin signalling necessitates unbiased methods enabling global detection of dynamic protein ubiquitylation.

Neddylation is essential for β-catenin degradation in Wnt signaling pathway

open access: yesCell Reports, 2022
Summary: β-Catenin is a central component in the Wnt signaling pathway; its degradation has been tightly connected to ubiquitylation, but it is rarely examined by loss-of-function assays.

Studying Protein Ubiquitylation in Yeast [PDF]

open access: yes, 2016
Ubiquitylation is a reversible posttranslational modification that is critical for most, if not all, cellular processes and essential for viability. Ubiquitin conjugates to substrate proteins either as a single moiety (monoubiquitylation) or as polymers composed of ubiquitin molecules linked to each other with various topologies and structures ...

An inhibitory mono-ubiquitylation of the Drosophila initiator caspase Dronc functions in both apoptotic and non-apoptotic pathways.

open access: yesPLoS Genetics, 2017
Apoptosis is an evolutionary conserved cell death mechanism, which requires activation of initiator and effector caspases. The Drosophila initiator caspase Dronc, the ortholog of mammalian Caspase-2 and Caspase-9, has an N-terminal CARD domain that ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Macromolecular juggling by ubiquitylation enzymes [PDF]

open access: yesBMC Biology, 2013
Abstract The posttranslational modification of target proteins with ubiquitin and ubiquitin-like proteins is accomplished by the sequential action of E1, E2, and E3 enzymes. Members of the E1 and E3 enzyme families can undergo particularly large conformational changes during their catalytic cycles, involving the remodeling of domain ...
