The Ran-GTP Gradient Spatially Regulates XCTK2 in the Spindle [PDF]

, 2015
SummaryRan is a small GTP binding protein that was originally identified as a regulator of nucleocytoplasmic transport [1] and subsequently found to be important for spindle formation [2–5].

Thermodynamic characterisation of covalent ligand binding

British Journal of Pharmacology, EarlyView.
Background and Purpose Differential scanning fluorimetry (DSF) is a common and straightforward method to evaluate the thermal stability of proteins and has been heavily used for ligand binding characterisation as well as for screening. One class of compounds that is less typically evaluated by DSF are covalent binders.

Potentiation effects of the positive allosteric modulator PTC‐174 on NMDA receptors in neonatal male rat substantia nigra dopaminergic neurons

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

The FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Structural intermediates in the assembly of taxoid-induced microtubules and GDP-tubulin double rings: time-resolved X-ray scattering [PDF]

, 1996
We have studied the self-association reactions of purified GDP-liganded tubulin into double rings and taxoid-induced microtubules, employing synchrotron time-resolved x-ray solution scattering.

Long‐read sequencing‐based atlas of tissue‐specific expression of DNM1L transcript variants

The FEBS Journal, EarlyView.
Targeted long‐read sequencing resolves full‐length DNM1L (Drp1) isoforms and reveals conserved, tissue‐specific expression patterns across human and mouse tissues. Functional assays show that Drp1 isoforms differ in their ability to drive mitochondrial fission, independent of abundance, with specific exons modulating activity.

The cationic region of Rhes mediates its interactions with specific Gβ subunits [PDF]

, 2009
Ras homologue enriched in striatum (Rhes) is a small monomeric G protein which functions in a variety of cellular processes, including attenuation of G protein-coupled receptor (GPCR)signalling.

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B

The FEBS Journal, EarlyView.
The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...

M1 macrophage‐derived exosomes aggravate diabetic nephropathy by regulating the WTAP/S1PR2 axis

Journal of Diabetes Investigation, EarlyView.
ABSTRACT Background Diabetic nephropathy (DN) is a severe microvascular complication of diabetes mellitus. The specific role of M1 macrophage‐derived exosomes in DN progression remains largely unexplored. Methods THP‐1 monocytes were differentiated into M0 macrophages and polarized into M1 macrophages for exosome extraction.
