Open AccessMolecular mechanism of the wake-promoting agent TAK-925
The OX2 orexin receptor (OX2R) is a highly expressed G protein-coupled receptor (GPCR) in the brain that regulates wakefulness and circadian rhythms in humans. Antagonism of OX2R is a proven therapeutic strategy ...

Open AccessSynthetic antibodies against BRIL as universal fiducial marks for single−particle cryoEM structure determination of membrane proteins
We propose the concept of universal fiducials based on a set of pre-made semi-synthetic antibodies (sABs) generated by customized phage display selections against the fusion protein BRIL, an engineered variant...

Open AccessStructure of formylpeptide receptor 2-Gi complex reveals insights into ligand recognition and signaling
Formylpeptide receptors (FPRs) as G protein-coupled receptors (GPCRs) can recognize formylpeptides derived from pathogens or host cells to function in host defense and cell clearance. In addition, FPRs, especi...

Open AccessAlzheimer’s disease-associated mutations increase amyloid precursor protein resistance to γ-secretase cleavage and the Aβ42/Aβ40 ratio
Mutations in the amyloid precursor protein (APP) gene and the aberrant cleavage of APP by γ-secretase are associated with Alzheimer’s disease (AD). Here we have developed a simple and sensitive cell-based assay t...

Destabilization of strigolactone receptor DWARF14 by binding of ligand and E3-ligase signaling effector DWARF3
Strigolactones (SLs) are endogenous hormones and exuded signaling molecules in plant responses to low levels of mineral nutrients. Key mediators of the SL signaling pathway in rice include the α/β-fold hydrola...

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

Structural basis for RNA recognition by a dimeric PPR-protein complex
Pentatricopeptide repeat (PPR) proteins are involved in different RNA processes, but how they recognize their target RNAs has been unclear. Now crystal structures of plant PPR protein–THA8 in complex with RNA,...

Knockdown of CD146 reduces the migration and proliferation of human endothelial cells
Our previous study has demonstrated that CD146 molecule is a biomarker on vascular endothelium, which is involved in angiogenesis and tumor growth. However the mechanism behind is not clear. Here we have for t...
