Rho GTPases as regulators of morphological neuroplasticity

, 2011
SummaryGTPases function as intracellular, bimolecular switches by adopting different conformational states in response to binding GDP or GTP. Their activation is mediated through cell-surface receptors.

Robustness of Spontaneous Polarization Through Nonlinear Directional Antagonism Without Global Inhibition

Journal of the Chinese Chemical Society, EarlyView.
The conventional “local activation–global inhibition” (LAGI) models utilize mean‐field averaging inhibition to suppress distant activations. As the inhibition diminishes with distance, LAGI models struggle to achieve robust single‐axis polarity in large systems.

Advances in GPCRs Associated With Wnt Signaling Within the Auditory System

Medicine Bulletin, EarlyView.
ABSTRACT G protein‐coupled receptors (GPCRs) that interact with the Wnt signaling pathway are pivotal for auditory system homeostasis, as they orchestrate inner ear development, hair cell (HC) regeneration, and hearing preservation. Frizzled (FZD) receptors, the core Wnt‐related GPCRs, bind Wnt ligands and co‐receptors (e.g., LRP5/6) to activate both ...

Rho-GTPases as key regulators of T lymphocyte biology

, 2014
International audienceRho-GTPases belong to the Ras superfamily and are crucial signal transducing proteins downstream of many receptors. In general, the Rho-GTPases function as molecular switches, cycling between inactive (GDP-bound) and active (GTP ...

Biomarkers of Leucine‐Rich Repeat Kinase 2 (LRRK2) and Lysosomal Dysfunction in Progressive Supranuclear Palsy

Movement Disorders, EarlyView.
Abstract Background Common and rare genetic variants in leucine‐rich repeat kinase 2 (LRRK2) have been linked with sporadic and familial Parkinson's disease (PD). Recently, we discovered that common genetic variation near the LRRK2 locus determined survival in progressive supranuclear palsy (PSP).

The toxin–antitoxin complex Fic‐1–AntF functions as a deAMPylase that regulates the activity of DNA gyrase

mLife, EarlyView.
Abstract Toxin–antitoxin (TA) systems found in diverse bacteria play important roles in their adaptation to changing environments. The toxin of the Fic‐1–AntF TA pair from Pseudomonas bijieensis strain 2P24 inhibits bacterial DNA replication by attacking the subunit B of DNA gyrase (GyrB) via AMPylation, while the antitoxin AntF blocks its enzymatic ...
