Exo70-Mediated Recruitment of Nucleoporin Nup62 at the Leading Edge of Migrating Cells is Required for Cell Migration [PDF]

, 2009
Nucleoporin Nup62 localizes at the central channel of the nuclear pore complex and is essential for nucleocytoplasmic transport. Through its FG-repeat domain, Nup62 regulates nuclear pore permeability and binds nuclear transport receptors.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Concerted action of the ubiquitin-fusion degradation protein 1 (Ufd1) and Sumo-targeted ubiquitin ligases (STUbLs) in the DNA-damage response. [PDF]

PLoS ONE, 2013
In eukaryotes many players in the DNA-damage response (DDR) catalyze protein sumoylation or ubiquitylation. Emphasis has been placed on how these modifications orchestrate the sequential recruitment of repair factors to sites of DNA damage or stalled ...

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.

The YoaW signal peptide directs efficient secretion of different heterologous proteins fused to a StrepII-SUMO tag in Bacillus subtilis

Microbial Cell Factories, 2019
Background Heterologous gene expression is well established for various prokaryotic model systems. However, low yield, incorrect folding and instability still impede the production of soluble, bioactive proteins.

Coordinated sumoylation and ubiquitination modulate EGF induced EGR1 expression and stability. [PDF]

PLoS ONE, 2011
Human early growth response-1 (EGR1) is a member of the zing-finger family of transcription factors induced by a range of molecular and environmental stimuli including epidermal growth factor (EGF).

The ALS‐associated E425K mutation uncouples DNAJC7 from the Hsp70 chaperone cycle

The FEBS Journal, EarlyView.
DNAJC7 is a J‐domain protein that plays a key role in protein quality control by regulating Hsp70 activity and preventing protein aggregation. We find that the ALS‐associated E425K mutation in DNAJC7 disrupts productive interaction and activation of Hsp70, thereby blocking the transfer and refolding of client proteins such as TDP‐43.

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation

The FEBS Journal, EarlyView.
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...

Enhanced Expression and Bioactivity Assessment of Recombinant SUMO-Protease-1 in E. coli BL21 (DE3) via Cleavage of His6-SMT3-SDF-1 Fusion Protein

Interdisciplinary Perspectives on Infectious Diseases
Background. The SUMO fusion system is advantageous in improving the solubility and correct folding of proteins that are difficult to produce. SUMO-protease-1 (Ulp1) is a key enzyme in this system, and its proper expression and purification in Escherichia
