Identification of E3 ligase substrates and PROTAC-induced ubiquitylation sites using proximity-based identification of ubiquitin sites (PrIUS) [PDF]

Communications Biology
The ubiquitin system regulates virtually all cellular processes, yet the vast majority of ubiquitylation sites identified in the human proteome cannot be attributed to specific E3 ligases.

Aging and diet alter the protein ubiquitylation landscape in the mouse brain

Nature Communications
Post-translational modifications (PTMs) regulate protein homeostasis, but how aging impacts PTMs remains unclear. Here, we used mass spectrometry to reveal changes in hundreds of protein ubiquitylation, acetylation, and phosphorylation sites in the mouse

Pacritinib abrogates the lupus phenotype in ABIN1[D485N] mice

Lupus Science and Medicine, 2023
Objective The aim of the study was to investigate whether the IRAK1/JAK2/Flt3 inhibitor pacritinib prevents disease development in the lupus-prone ABIN1[D485N] knock-in mouse.Methods ABIN1[D485N] knock-in mice aged 8 weeks were fed for 10 weeks on a diet

IL-15 and PIM kinases direct the metabolic programming of intestinal intraepithelial lymphocytes

Nature Communications, 2021
Intraepithelial lymphocytes (IEL) respond to IL-15 complexed with IL-15Ra but how this intrinsically affects IEL is unclear. Here the authors use proteomics analyses of the main mouse IEL subsets and identify PIM kinases as essential for IEL ...

Pathogenic FAM83G palmoplantar keratoderma mutations inhibit the PAWS1:CK1α association and attenuate Wnt signalling. [version 2; peer review: 2 approved]

Wellcome Open Research, 2020
Background: Two recessive mutations in the FAM83G gene, causing A34E and R52P amino acid substitutions in the DUF1669 domain of the PAWS1 protein, are associated with palmoplantar keratoderma (PPK) in humans and dogs respectively.

A novel RLIM/RNF12 variant disrupts protein stability and function to cause severe Tonne–Kalscheuer syndrome

Scientific Reports, 2021
Tonne–Kalscheuer syndrome (TOKAS) is an X-linked intellectual disability syndrome associated with variable clinical features including craniofacial abnormalities, hypogenitalism and diaphragmatic hernia.

CMG helicase disassembly is controlled by replication fork DNA, replisome components and a ubiquitin threshold

eLife, 2020
The eukaryotic replisome assembles around the CMG helicase, which stably associates with DNA replication forks throughout elongation. When replication terminates, CMG is ubiquitylated on its Mcm7 subunit and disassembled by the Cdc48/p97 ATPase.

Pathogenic FAM83G palmoplantar keratoderma mutations inhibit the PAWS1:CK1α association and attenuate Wnt signalling. [version 1; peer review: 2 approved]

Wellcome Open Research, 2019
Background: Two recessive mutations in the FAM83G gene, causing A34E and R52P amino acid substitutions in the DUF1669 domain of the PAWS1 protein, are associated with palmoplantar keratoderma (PPK) in humans and dogs respectively.

Mapping of a N-terminal α-helix domain required for human PINK1 stabilization, Serine228 autophosphorylation and activation in cells

Open Biology, 2022
Autosomal recessive mutations in the PINK1 gene are causal for Parkinson's disease (PD). PINK1 encodes a mitochondrial localized protein kinase that is a master-regulator of mitochondrial quality control pathways.

Remodeling Membrane Binding by Mono-Ubiquitylation

Biomolecules, 2019
Ubiquitin (Ub) receptors respond to ubiquitylation signals. They bind ubiquitylated substrates and exert their activity in situ. Intriguingly, Ub receptors themselves undergo rapid ubiquitylation and deubiquitylation.
