Phosphoproteomics identifies a bimodal EPHA2 receptor switch that promotes embryonic stem cell differentiation

Nature Communications, 2020
Fgf4 is a critical signal driving embryonic stem cell (ESC) exit from pluripotency and differentiation. Here the authors identify EPHA2 as a target of FGF4 signalling in ESCs, and show that EPHA2-EFNA1 signalling promotes pluripotent gene expression and ...

Targeted dephosphorylation of SMAD3 as an approach to impede TGF-β signaling

iScience
Summary: TGF-β (transforming growth factor-β) signaling is involved in a myriad of cellular processes and its dysregulation has been implicated in many human diseases, including fibrosis and cancer.

CMG helicase disassembly is essential and driven by two pathways in budding yeast

The EMBO Journal
The CMG helicase is the stable core of the eukaryotic replisome and is ubiquitylated and disassembled during DNA replication termination. Fungi and animals use different enzymes to ubiquitylate the Mcm7 subunit of CMG, suggesting that CMG ubiquitylation ...

PINK1 regulated mitophagy is evident in skeletal muscles

Autophagy Reports
PINK1, mutated in familial forms of Parkinson’s disease, initiates mitophagy following mitochondrial depolarization. However, it is difficult to monitor this pathway physiologically in mice as loss of PINK1 does not alter basal mitophagy levels in most ...

In Vitro Reconstitution Defines the Minimal Requirements for Cdc48-Dependent Disassembly of the CMG Helicase in Budding Yeast

Cell Reports, 2019
Summary: Disassembly of the replisome is the final step of chromosome duplication in eukaryotes. In budding yeast and metazoa, cullin ubiquitin ligases are required to ubiquitylate the Cdc45-MCM-GINS (CMG) helicase that lies at the heart of the replisome,

Neurymenolide A, a Novel Mitotic Spindle Poison from the New Caledonian Rhodophyta Phacelocarpus neurymenioides

Marine Drugs, 2019
The marine α-pyrone macrolide neurymenolide A was previously isolated from the Fijian red macroalga, Neurymenia fraxinifolia, and characterized as an antibacterial agent against antibiotic-resistant strains that also exhibited moderate cytotoxicity ...

Targeted dephosphorylation of TFEB promotes its nuclear translocation

iScience
Summary: Reversible phosphorylation of the transcription factor EB (TFEB) coordinates cellular responses to metabolic and other stresses. During nutrient replete and stressor-free conditions, phosphorylated TFEB is primarily localized to the cytoplasm ...

Characterisation of the Cullin‐3 mutation that causes a severe form of familial hypertension and hyperkalaemia

EMBO Molecular Medicine, 2015
Deletion of exon 9 from Cullin‐3 (CUL3, residues 403–459: CUL3Δ403–459) causes pseudohypoaldosteronism type IIE (PHA2E), a severe form of familial hyperkalaemia and hypertension (FHHt).

Activation of AMPK as a therapeutic strategy for FBXL4-related mitochondrial DNA depletion syndrome

EMBO Molecular Medicine
Distinct mitophagy pathways can eliminate not only damaged mitochondria but also healthy ones. In Mitochondrial DNA Depletion Syndrome 13 (MTDPS13), dysregulated BNIP3/NIX-driven mitophagy of functional mitochondria is thought to be the key pathological ...
