Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

Advanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Molecular Dissection of the Semaphorin 4D Receptor Plexin-B1-Stimulated R-Ras GTPase-Activating Protein Activity and Neurite Remodeling in Hippocampal Neurons

Journal of Neuroscience, 2004
Plexins serve as receptors for repulsive axonal guidance molecules semaphorins. The cytoplasmic domain of the semaphorin 4D (Sema4D) receptor, Plexin-B1 has two separated Ras GTPase-activating protein (GAP)-homologous domains, C1 and C2.

A CMTM6 Nanobody Overcomes EGFR‐TKI Resistance in Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
Overcoming EGFR‐TKI resistance remains a critical challenge in NSCLC treatment. This study identifies CMTM6 as a key regulator of EGFR stability and demonstrates that a novel anti‐CMTM6 nanobody disrupts the CMTM6‐EGFR interaction. Targeting CMTM6 restores EGFR degradation, suppresses tumor growth, and confers therapeutic benefit in both CDX and PDX ...

Activation of ADP-ribosylation Factor 1 GTPase-Activating Protein by Phosphatidylcholine-derived Diacylglycerols*

Journal of Biological Chemistry, 1997
Disassembly of the coatomer from Golgi vesicles requires that the small GTP-binding protein ADP-ribosylation factor 1 (ARF1) hydrolyzes its bound GTP by the action of a GTPase-activating protein.

H3K36me3‐Guided m6A Modification of Oncogenic L1CAM‐AS1 Drives Macrophage Polarization and Immunotherapy Resistance in Hepatocellular Carcinoma

Advanced Science, EarlyView.
L1CAM‐AS1 is identified as a novel H3K36me3‐guided, m6A‐modified long noncoding RNA (lncRNA) in hepatocellular carcinoma (HCC) cells. L1CAM‐AS1 stabilizes RAN protein, enhances M2 macrophages‐released CCL5‐induced nuclear import of RELA, activates the NF‐κB signaling, up‐regulates CCL2 expression and secretion from HCC cells, and enhances M2 ...

Coordinate regulation of G protein signaling via dynamic interactions of receptor and GAP.

PLoS Computational Biology, 2008
Signal output from receptor-G-protein-effector modules is a dynamic function of the nucleotide exchange activity of the receptor, the GTPase-accelerating activity of GTPase-activating proteins (GAPs), and their interactions. GAPs may inhibit steady-state

Roles of G proteins and their GTPase-activating proteins in platelets

Bioscience Reports
AbstractPlatelets are small anucleate blood cells supporting vascular function. They circulate in a quiescent state monitoring the vasculature for injuries. Platelets adhere to injury sites and can be rapidly activated to secrete granules and to form platelet/platelet aggregates.

Phospholipases as GTPase activity accelerating proteins (GAPs) in plants [PDF]

Plant Signaling & Behavior, 2016
GTPase activity accelerating proteins (GAPs) are key regulators of the G-protein signaling cycle. By facilitating effective hydrolysis of the GTP bound on Gα proteins, GAPs control the timing and amplitude of the signaling cycle and ascertain the availability of the inactive heterotrimer for the next round of activation.

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

Advanced 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 ...
