Small GTP-binding protein PdRanBP regulates vascular tissue development in poplar
BMC Genetics, 2016 Previous research has demonstrated that ectopic expression of Ran-binding protein (RanBP) in Arabidopsis results in more axillary buds and reduced apical dominance compared to WT plants. However, the function of RanBP in poplar, which has very typical secondary growth, remains unclear.

Advanced Science, EarlyView.This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis
Hepatology, EarlyView., 2022 EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

RGS10 shapes the hemostatic response to injury through its differential effects on intracellular signaling by platelet agonists. [PDF]
, 2018 Platelets express ≥2 members of the regulators of G protein signaling (RGS) family. Here, we have focused on the most abundant, RGS10, examining its impact on the hemostatic response in vivo and the mechanisms involved.

Both Ligand- and Cell-Specific Parameters Control Ligand Agonism in a Kinetic Model of G Protein–Coupled Receptor Signaling [PDF]
, 2007 G protein–coupled receptors (GPCRs) exist in multiple dynamic states (e.g., ligand-bound, inactive, G protein–coupled) that influence G protein activation and ultimately response generation. In quantitative models of GPCR signaling that incorporate these

STING COPII ER Export Trafficking and Signaling Primed by Phosphorylation Switches
Advanced Science, EarlyView.This schematic outlines STING trafficking and signaling via coat protein II (COPII)‐mediated endoplasmic reticulum (ER) export. Following cyclic GMP‐AMP (cGAMP) stimulation, TANK‐binding kinase 1 (TBK1) activates on COPII vesicles, partially dissociating into the cytosol to phosphorylate ER‐localized STING, creating pSGME/pFS COPII‐sorting motifs ...

Open and cut: allosteric motion and membrane fission by dynamin superfamily proteins. [PDF]
, 2019 Cells have evolved diverse protein-based machinery to reshape, cut, or fuse their membrane-delimited compartments. Dynamin superfamily proteins are principal components of this machinery and use their ability to hydrolyze GTP and to polymerize into ...
