Structural basis for the tethered peptide activation of adhesion GPCRs
Adhesion G-protein-coupled receptors (aGPCRs) are important for organogenesis, neurodevelopment, reproduction and other processes1–6. Many aGPCRs are activated by a conserved internal (tethered) agonist sequence ...

Open AccessStructural studies of phosphorylation-dependent interactions between the V2R receptor and arrestin-2
Arrestins recognize different receptor phosphorylation patterns and convert this information to selective arrestin functions to expand the functional diversity of the G protein-coupled receptor (GPCR) superfam...

STING controls nociception via type I interferon signalling in sensory neurons
The innate immune regulator STING is a critical sensor of self- and pathogen-derived DNA. DNA sensing by STING leads to the induction of type-I interferons (IFN-I) and other cytokines, which promote immune-cel...

Structures of the glucocorticoid-bound adhesion receptor GPR97–Go complex
Adhesion G-protein-coupled receptors (GPCRs) are a major family of GPCRs, but limited knowledge of their ligand regulation or structure is available1–3. Here we report that glucocorticoid stress hormones activate...

Open AccessChloroplast genomes elucidate diversity, phylogeny, and taxonomy of Pulsatilla (Ranunculaceae)
Pulsatilla (Ranunculaceae) consists of about 40 species, and many of them have horticultural and/or medicinal value. However, it is difficult to recognize and identify wild Pulsatilla species. Universal molecular...

Open Accessβ-arrestin-2 regulates NMDA receptor function in spinal lamina II neurons and duration of persistent pain
Mechanisms of acute pain transition to chronic pain are not fully understood. Here we demonstrate an active role of β-arrestin 2 (Arrb2) in regulating spinal cord NMDA receptor (NMDAR) function and the duratio...
