A P-loop mutation in Gα subunits prevents transition to the active state: implications for G-protein signaling in fungal pathogenesis.

PLoS Pathogens, 2012
Heterotrimeric G-proteins are molecular switches integral to a panoply of different physiological responses that many organisms make to environmental cues.

A method for the prediction of GPCRs coupling specificity to G-proteins using refined profile Hidden Markov Models

BMC Bioinformatics, 2005
Background G- Protein coupled receptors (GPCRs) comprise the largest group of eukaryotic cell surface receptors with great pharmacological interest. A broad range of native ligands interact and activate GPCRs, leading to signal transduction within cells.

CXCL12/SDF-1 and CXCR4 [PDF]

, 2015
Chemokines are a large family of structurally related chemoattractive cytokines, which have four conserved cysteines forming two disulfide bonds, and act through seven-transmembrane-spanning receptors coupled to heterotrimeric GTP-binding proteins (G ...

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.

Cyclic AMP concentrations in dendritic cells induce and regulate Th2 immunity and allergic asthma [PDF]

, 2015
The inductive role of dendritic cells (DC) in Th2 differentiation has not been fully defined. We addressed this gap in knowledge by focusing on signaling events mediated by the heterotrimeric GTP binding proteins Gαs, and Gαi, which respectively ...

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Trisoxazole Macrolides Potentiate the Microtubule Assembly and Antimitotic Activities of Taxanes

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Photoaffinity experiments identified tubulin as a new target of mycalolides. Though weakly cytotoxic, the trisoxazole macrolactone moiety enhanced paclitaxel's microtubule assembly and antimitotic effects. Molecular modeling studies suggested that MyC stabilizes α/β‐tubulin heterodimer interactions.

RASD2 Drives Renal Clear Cell Carcinoma Progression via RAF1 (Ser338) Phosphorylation

Cancer Science, EarlyView.
RASD2 drives clear cell renal cell carcinoma (ccRCC) progression by physically interacting with RAF1 to induce its Ser338 phosphorylation, which subsequently activates the P38/ERK–MAPK signaling pathway to promote malignant tumor phenotypes and poor prognosis.

TARGETS FOR MAJORITY OF DRUGS: G PROTEIN-COUPLED RECEPTORS - THEIR STRUCTURE AND INTERACTIONS WITH BIOLIGANDS

TASK Quarterly, 2021
G protein-coupled receptors (GPCRs) are the most frequent targets for many drugs. They form the largest superfamily of integral membrane proteins, of which more than 1000 members have the following common features: (i) All GPCRs form 7 hydrophobic a ...

Longitudinal Phenotypic Trajectories in GNAO1‐Related Disorders: Defining Disease Progression and Clinical Profiles

Annals of Neurology, Volume 100, Issue 1, Page 154-170, July 2026.
Objective Pathogenic variants in GNAO1 cause a spectrum of epilepsy, movement disorders, and developmental impairment. Clinical heterogeneity complicates prognosis and therapeutic development. We present the first longitudinal natural history study of GNAO1‐related disorders (GNAO1‐RD) to delineate phenotypic trajectories. Methods Sixty‐six individuals
