Nomenclature for the human Arf family of GTP-binding proteins: ARF, ARL, and SAR proteins

open access: yesJournal of Cell Biology, 2006
The Ras superfamily is comprised of at least four large families of regulatory guanosine triphosphate–binding proteins, including the Arfs. The Arf family includes three different groups of proteins: the Arfs, Arf-like (Arls), and SARs.

Simultaneous Monitoring of Tyrosinase and ATP in Thick Brain Tissues Using a Single Two‐Photon Fluorescent Probe

open access: yesAdvanced Science, Volume 12, Issue 19, May 22, 2025.
A single dual‐emission two‐photon fluorescent probe is designed for simultaneously tracking tyrosinase (TYR) and adenosine triphosphate (ATP). With the help of this probe, the intricate correlation and regulatory mechanism between TYR and ATP during oxidative stress is uncovered.

Molecular architecture of Gαo and the structural basis for RGS16-mediated deactivation [PDF]

open access: yes, 2008
Heterotrimeric G proteins relay extracellular cues from heptahelical transmembrane receptors to downstream effector molecules. Composed of an α subunit with intrinsic GTPase activity and a βγ heterodimer, the trimeric complex dissociates upon receptor ...

Actin filament organization in activated mast cells is regulated by heterotrimeric and small GTP-binding proteins

open access: yesJournal of Cell Biology, 1994
Rat peritoneal mast cells, both intact and permeabilized, have been used widely as model secretory cells. GTP-binding proteins and calcium play a major role in controlling their secretory response.

RAB3B Dictates mTORC1/S6 Signaling in Chordoma and Predicts Response to mTORC1‐Targeted Therapy

open access: yesAdvanced Science, Volume 12, Issue 19, May 22, 2025.
RAB3B is unveiled as a prominent oncogenic regulator in chordoma, which can block the DUSP12‐mediated dephosphorylation of p‐S6 (S235/236). The combination of RAB3B and p‐S6 indicates a good prognostic value and predicts mTORC1 inhibitors response for chordoma patients.

Protein Secretion and GTP-binding Proteins.

open access: yesSeibutsu Butsuri, 1991
GTP-binding proteins are involved in a wide variety of cellular functions. One of the most recent findings is the implication of many GTP-binding proteins in the pathway of protein secretion. In the eukaryotic secretory pathway, proteins have to be sorted from each other at many steps, including the signal recognition and translocation across the ...

The F-actin filament capping protein CapG is a bona fide nucleolar protein [PDF]

open access: yes, 2008
Actin works in concert with myosin I to regulate the transcription of ribosomal genes in the nucleolus. Recently, nucleolar actin has been shown to be active in its polymeric form raising the question how actin dynamics is regulated in the nucleolus ...

The small GTP-binding proteins, Rac and Rho, regulate cytoskeletal organization and exocytosis in mast cells by parallel pathways.

open access: yesMolecular Biology of the Cell, 1996
In mast cells, activation of GTP-binding proteins induces centripetal reorganization of actin filaments. This effect is due to disassembly, relocalization, and polymerization of F-actin and is dependent on two small GTPases, Rac and Rho.

Oxytocin Improves Autistic Behaviors by Positively Shifting GABA Reversal Potential via NKCC1 in Early‐Postnatal‐Stage

open access: yesAdvanced Science, EarlyView.
New research reveals that oxytocin signaling during the early postnatal period is critical for regulating brain development and social behavior. Selectively suppressing oxytocin neurons by chemogenetic method shows that early—but not late—disruption leads to autism‐like behaviors.
