Reconstructed evolutionary history of the yeast septins Cdc11 and Shs1

open access: yesG3: Genes, Genomes, Genetics, 2020
Septins are GTP-binding proteins conserved across metazoans. They can polymerize into extended filaments and, hence, are considered a component of the cytoskeleton.

Aminoacyl-tRNA-charged eukaryotic elongation factor 1A is the bona fide substrate for Legionella pneumophila effector glucosyltransferases. [PDF]

open access: yesPLoS ONE, 2011
Legionella pneumophila, which is the causative organism of Legionnaireś disease, translocates numerous effector proteins into the host cell cytosol by a type IV secretion system during infection.

Cloning and characterisation of genes determining pod morphology in pea [PDF]

open access: yes, 1994
Genes expressed in developing pea pods were isolated as cDNAs by differential screening techniques. The cDNAs were characterised by DNA sequencing and expression studies were used to investigate the role of isolated cDNAs in pod development.

Reconstitution of receptors and GTP-binding regulatory proteins (G Proteins) in Sf9 Cells: a direct evaluation of selectivity in receptor.G protein coupling

open access: yes, 1997
The selectivity in coupling of various receptors to GTP-binding regulatory proteins (G proteins) was examined directly by a novel assay entailing the use of proteins overexpressed in Spodoptera frugiperda (Sf9) cells.

The pH dependence of polymerization and bundling by the essential bacterial cytoskeltal protein FtsZ [PDF]

open access: yes, 2011
There is a growing body of evidence that bacterial cell division is an intricate coordinated process of comparable complexity to that seen in eukaryotic cells.

Selenium Nanoparticles Selectively Target KRAS G13D to Inhibit Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
The mechanisms of SeNPs therapy in cancer treatment, encompass three parallel actions: (1) seleno‐amino acids, key metabolites, upregulate GPX2 expression, thereby inhibiting tumor metastasis via the GPX2‐HIF1α‐VEGF signaling pathway; (2) selenite (SeO32−), an inorganic metabolite, forms hydrogen bonds with amino acid residues 13–17 of the KRAS G13D ...

Rabs, Rips, FIPs, and Endocytic Membrane Traffic

open access: yesThe Scientific World Journal, 2003
Rab GTPases, proteins belonging to the Ras-like small GTP-binding protein superfamily, have emerged as master regulators of cellular membrane transport.

Gm26550 Modulates Learning and Memory by Increasing IGF1 mRNA Expression and Stability in Nrf2−/− Mice

open access: yesAdvanced Science, EarlyView.
The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

open access: yesHepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Characterization of the GTPγS release function of a G protein-coupled receptor

open access: yesNature Communications
G protein-coupled receptor (GPCR) signaling is one of the most ubiquitous and sensitive forms of cell surface reception. GPCRs stabilize the nucleotide-free state of heterotrimeric guanine-nucleotide binding proteins (G proteins); however, this state is ...
