Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Molecular architecture of meiotic multiprotein complexes

, 2020
Sich sexuell fortpflanzende Organismen sind auf die Meiose angewiesen, um haploide, genetisch vielfältige Keimzellen zu erzeugen, die die Stabilität des Genoms und die Fähigkeit zur Anpassung an sich verändernde Umgebungen erhalten. Die Haploidisierung wird durch zwei aufeinanderfolgende Runden der Zellteilung nach einer einzigen anfänglichen prä ...

Dissociating role of Bassoon in glutamatergic and dopaminergic neurons in alcohol‐related behaviour and affective state in mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Alcohol abuse and affective disorders are severe comorbid psychiatric diseases characterized by impaired brain synaptic transmission. The role of presynaptic scaffolding proteins coordinating presynaptic plasticity and neurotransmitter release, such as Bassoon (Bsn), in the pathogenesis of these disorders remains elusive.

Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

The FEBS Journal, EarlyView.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Phosphorylation-mediated interactions with TOPBP1 couple 53BP1 and 9-1-1 to control the G1 DNA damage checkpoint

eLife, 2019
Coordination of the cellular response to DNA damage is organised by multi-domain ‘scaffold’ proteins, including 53BP1 and TOPBP1, which recognise post-translational modifications such as phosphorylation, methylation and ubiquitylation on other proteins ...

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

The FEBS Journal, EarlyView.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),

Architecture of the human mTORC2 core complex

eLife, 2018
The mammalian target of rapamycin (mTOR) is a key protein kinase controlling cellular metabolism and growth. It is part of the two structurally and functionally distinct multiprotein complexes mTORC1 and mTORC2.

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

The FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular

Current perspectives on KMT2A fusion proteins and menin inhibition in paediatric acute myeloid leukaemia

The FEBS Journal, EarlyView.
Genetic rearrangements resulting in the expression of KMT2A fusion alleles can lead to dramatic transcriptional disturbances that contribute to the onset of acute leukaemias. Fortunately, menin inhibition has emerged as a promising new class of targeted therapy.
