Functional significance may underlie the taxonomic utility of single amino acid substitutions in conserved proteins [PDF]
, 2010 We hypothesized that some amino acid substitutions in conserved proteins that are strongly fixed by critical functional roles would show lineage-specific distributions.

Advanced Science, EarlyView.This study revealed that adiponectin facilitates the therapeutic efficiency of thrombopoietic agents by stimulating the membrane trafficking of c‐Mpl in MKs, which provides a point for ITP therapy. Moreover, a novel c‐Mpl trafficking mechanism based on the Myosin‐9/Rab6A complex is constructed. These findings provide new insights into the applicability

Structural Insights into the Regulation Mechanism of Small GTPases by GEFs
Molecules, 2019 Small GTPases are key regulators of cellular events, and their dysfunction causes many types of cancer. They serve as molecular switches by cycling between inactive guanosine diphosphate (GDP)-bound and active guanosine triphosphate (GTP)-bound states ...

The hierarchical assembly of septins revealed by high-speed AFM
Nature Communications, 2020 Septins are GTP-binding proteins involved in diverse cellular processes including division, polarity maintenance and membrane remodeling. Here authors use high-speed atomic force microscopy to show that assembly of septin filaments is a diffusion-driven ...

Translation termination depends on the sequential ribosomal entry of eRF1 and eRF3.
, 2019 Translation termination requires eRF1 and eRF3 for polypeptide-and tRNA-release on stop codons. Additionally, Dbp5/DDX19 and Rli1/ABCE1 are required; however, their function in this process is currently unknown.

Phosphorylation stoichiometries of human eukaryotic initiation factors. [PDF]
, 2014 Eukaryotic translation initiation factors are the principal molecular effectors regulating the process converting nucleic acid to functional protein. Commonly referred to as eIFs (eukaryotic initiation factors), this suite of proteins is comprised of at ...

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.

Specific Rab GTPase-activating proteins define the Shiga toxin and epidermal growth factor uptake pathways [PDF]
, 2007 Rab family guanosine triphosphatases (GTPases) together with their regulators define specific pathways of membrane traffic within eukaryotic cells. In this study, we have investigated which Rab GTPase-activating proteins (GAPs) can interfere with the ...

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 ...
