RANBP3 and RAN orchestrate CRM1-mediated nuclear export of hepatitis B virus RNAs [PDF]

Journal of Virology
Nuclear export of viral RNAs is essential for the replication of hepatitis B virus (HBV). Our previous study demonstrated that ELAVL1 (embryonic lethal, abnormal vision, Drosophila-like 1) mediates the nuclear export of HBV RNAs via the chromosome region

Mechanistic insights into the effect of phosphorylation on Ras conformational dynamics and its interactions with cell signaling proteins

Computational and Structural Biotechnology Journal, 2021
Ras undergoes interconversion between the active GTP-bound state and the inactive GDP-bound state. This GTPase cycle, which controls the activities of Ras, is accelerated by Ras GTPase-activating proteins (GAPs) and guanine nucleotide exchange factors ...

Wheat TaRab7 GTPase is part of the signaling pathway in responses to stripe rust and abiotic stimuli. [PDF]

PLoS ONE, 2012
Small GTP-binding proteins function as regulators of specific intercellular fundamental biological processes. In this study, a small GTP-binding protein Rab7 gene, designated as TaRab7, was identified and characterized from a cDNA library of wheat leaves

Regulation of lymphocyte-mediated killing by GTP-binding proteins [PDF]

Journal of Leukocyte Biology, 2003
Abstract Exocytosis of granules containing apoptosis-inducing proteins is one mechanism of target cell killing by cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. Granules containing perforin and granzymes are redistributed to the area of cell contact initiated by specific interactions between surface ligands on a target ...

Posttranslational modification of the RHO of plants protein RACB by phosphorylation and cross-kingdom conserved ubiquitination.

PLoS ONE, 2022
Small RHO-type G-proteins act as signaling hubs and master regulators of polarity in eukaryotic cells. Their activity is tightly controlled, as defective RHO signaling leads to aberrant growth and developmental defects.

Oxytocin Downregulates the Ca_V1.2 L-Type Ca²⁺ Channel via Gi/cAMP/PKA/CREB Signaling Pathway in Cardiomyocytes

Membranes, 2021
Oxytocin (OT) and its receptor (OTR) are expressed in the heart and are involved in the physiological cardiovascular functional system. Although it is known that OT/OTR signaling is cardioprotective by reducing the inflammatory response and improving ...

Rho GTPases as Key Molecular Players within Intestinal Mucosa and GI Diseases

Cells, 2021
Rho proteins operate as key regulators of the cytoskeleton, cell morphology and trafficking. Acting as molecular switches, the function of Rho GTPases is determined by guanosine triphosphate (GTP)/guanosine diphosphate (GDP) exchange and their lipidation

Oncogene ect2 is related to regulators of small GTP-binding proteins [PDF]

Nature, 1993
We have developed an efficient expression cloning system that allows rapid isolation of complementary DNAs able to induce the transformed phenotype. We searched for molecules expressed in epithelial cells and possessing transforming potential to fibroblasts, and cloned a cDNA for the normal receptor of a growth factor secreted by NIH/3T3 cells. Here we
