Ras signaling through RASSF proteins [PDF]
Seminars in Cell & Developmental Biology, 2016 There are six core RASSF family proteins that contain conserved Ras Association domains and may serve as Ras effectors. They lack intrinsic enzymatic activity and appear to function as scaffolding and localization molecules. While initially being associated with pro-apoptotic signaling pathways such as Bax and Hippo, it is now clear that they can also ...

Dissecting the different biological effects of oncogenic Ras isoforms in cancer cell lines: could stimulation of oxidative stress be the one more weapon of H-Ras? Regulation of oxidative stress and Ras biological effects [PDF]
, 2012 Ras proteins are small GTPase functioning as molecular switches that, in response to particular extracellular signalling, as growth factors, activate a diverse array of intracellular effector cascades regulating cell proliferation, differentiation and ...

eLife, 2018 While there have been tremendous efforts to target oncogenic RAS signaling from inside the cell, little effort has focused on the cell-surface. Here, we used quantitative surface proteomics to reveal a signature of proteins that are upregulated on cells ...

A conserved, N-terminal tyrosine signal directs Ras for inhibition by Rabex-5.
PLoS Genetics, 2020 Dysregulation of the Ras oncogene in development causes developmental disorders, "Rasopathies," whereas mutational activation or amplification of Ras in differentiated tissues causes cancer.

Cell cycle-dependent activation of Ras [PDF]
, 1996 Background Ras proteins play an essential role in the transduction of signals from a wide range of cell-surface receptors to the nucleus. These signals may promote cellular proliferation or differentiation, depending on the cell background.

Targeting Ras with protein engineering
Oncotarget, 2023 Ras proteins are small GTPases that regulate cell growth and division. Mutations in Ras genes are associated with many types of cancer, making them attractive targets for cancer therapy. Despite extensive efforts, targeting Ras proteins with small molecules has been extremely challenging due to Ras's mostly flat surface and lack of small molecule ...

Dominant yeast and mammalian RAS mutants that interfere with the CDC25-dependent activation of wild-type RAS in Saccharomyces cerevisiae [PDF]
, 1989 Two mutant alleles of RAS2 were discovered that dominantly interfere with wild-type RAS function in the yeast Saccharomyces cerevisiae. An amino acid substitution which caused the dominant interference was an alanine for glycine at position 22 or a ...
