Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The search for novel insecticide targets in the post-genomics era, with a specific focus on G-protein coupled receptors

open access: yesMemorias do Instituto Oswaldo Cruz
Insects are considered pests globally, implicated in the destruction of agricultural fields and transmission of pathogens that cause deadly human diseases, such as dengue, Zika and malaria.

Glycoprotein G-protein Coupled Receptors in Disease: Luteinizing Hormone Receptors and Follicle Stimulating Hormone Receptors

open access: yesDiseases, 2020
Signal transduction by luteinizing hormone receptors (LHRs) and follicle-stimulating hormone receptors (FSHRs) is essential for the successful reproduction of human beings.

The Pathways Connecting G Protein-coupled Receptors to the Nucleus through Divergent Mitogen-activated Protein Kinase Cascades*

open access: yesJournal of Biological Chemistry, 1998
Receptors coupled to heterotrimeric GTP-binding proteins (G proteins) are integral membrane proteins involved in the transmission of signals from the extracellular environment to the cytoplasm. The best known family of G protein-coupled receptors (GPCRs),

Threonine 180 Is Required for G-protein-coupled Receptor Kinase 3- and β-Arrestin 2-mediated Desensitization of the µ-Opioid Receptor in Xenopus Oocytes [PDF]

open access: yes, 2001
To determine the sites in the µ-opioid receptor (MOR) critical for agonist-dependent desensitization, we constructed and coexpressed MORs lacking potential phosphorylation sites along with G-protein activated inwardly rectifying potassium channels ...

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser. [PDF]

open access: yes, 2015
G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Genetic Polymorphisms of Prokineticins and Prokineticin Receptors Associated with Human Disease

open access: yesLife
Prokineticins (PKs) are low molecular weight proteins that exert their effects by binding to two seven-transmembrane G-protein-coupled receptors (prokineticin receptors, PKRs).

G Protein-Coupled Receptors in the Mammalian Blood-Brain Barrier

open access: yesFrontiers in Cellular Neuroscience, 2020
The mammalian neurovascular unit (NVU) is comprised of neurons, glia, and vascular cells. The NVU is the nexus between the cardiovascular and central nervous system (CNS).

G protein-coupled receptors in neurodegenerative diseases and psychiatric disorders

open access: yesSignal Transduction and Targeted Therapy, 2023
Neuropsychiatric disorders are multifactorial disorders with diverse aetiological factors. Identifying treatment targets is challenging because the diseases are resulting from heterogeneous biological, genetic, and environmental factors.
