Nanoscale Curvature Regulates YAP/TAZ Nuclear Localization Through Nuclear Deformation and Rupture

open access: yesAdvanced Science, EarlyView.
This study uses experiments and biophysical modeling to examine the response and adaptation of cells to nanoscale topography of surfaces. It is shown that cytoskeletal assembly and nuclear localization of transcription regulatory factors such as yes‐associated protein (YAP) and transcriptional coactivator with PDZ‐binding motif (TAZ) can be tuned by ...

Light‐Triggered CRISPR/Cas12a for Genomic Editing and Tumor Regression

open access: yesAngewandte Chemie, EarlyView.
A photo‐triggered CRISPR/Cas12a machinery for gene editing is introduced. The machinery is applied for endogenous DNA methyltransferase 1 (DNMT1) gene editing and for in vitro disruption of the hepatocyte growth factor (HGF) gene. The machinery is used for in vivo knockout and disruption of the HGF gene in HepG2 tumors, resulting in effective apoptosis

Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]

open access: yes, 2017
Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Adducin‐1 Facilitates Influenza Virus Endosomal Trafficking and Uncoating by Regulating Branched Actin Dynamics and Myosin IIB Activity

open access: yesAdvanced Science, EarlyView.
In this study, a novel mechanism is unveiled by which ADD1, acting as a molecular switch, coordinates actin branch dynamics and the transport of endocytic viruses and cargoes. Phosphorylation of ADD1 at Ser726 reduces actin branch density, enhancing endosome fusion and attachment to microtubules.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]

open access: yes, 2002
Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

Dipyridamole Acts as Clinical Ferroptosis Inhibitor to Prevent from Tissue Injury

open access: yesAdvanced Science, EarlyView.
Dipyridamole acts as a clinically used compound to suppress ferroptosis. Dipyridamole down‐regulates the expression of RNF126, which is an E3 ligase to ubiquitinate SLC7A11 for proteasome degradation. The deficiency of SLC7A11 largely abolishes the protective role of dipyridamole both in vitro and in vivo.

The beta subunit of the signal recognition particle receptor is a transmembrane GTPase that anchors the alpha subunit, a peripheral membrane GTPase, to the endoplasmic reticulum membrane. [PDF]

open access: yes, 1995
The signal recognition particle receptor (SR) is required for the cotranslational targeting of both secretory and membrane proteins to the endoplasmic reticulum (ER) membrane.

Reciprocal regulation of PKA and rac signaling [PDF]

open access: yes, 2013
Activated G protein-coupled receptors (GPCRs) and receptor tyrosine kinases relay extracellular signals through spatial and temporal controlled kinase and GTPase entities.

In Vivo Cytosolic Delivery of Biomolecules into Neurons for Super‐Resolution Imaging and Genome Modification

open access: yesAdvanced Science, EarlyView.
The N1 peptide specifically targets neurons, enabling cytosolic delivery of fluorescent dyes and proteins for super‐resolution imaging and functional genetic modification. Abstract Efficient delivery of biomolecules into neurons has significant impacts on therapeutic applications in the central nervous system (CNS) and fundamental neuroscience research.

Substrate binding disrupts dimerization and induces nucleotide exchange of the chloroplast GTPase Toc33

open access: yes, 2011
GTPases act as molecular switches to control many cellular processes, including signalling, protein translation and targeting. Switch activity can be regulated by external effector proteins or intrinsic properties, such as dimerization.
