Targeting RAS-driven human cancer cells with antibodies to upregulated and essential cell-surface proteins

open access: yeseLife, 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.

open access: yesPLoS 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.

Ras-GRF Activates Ha-Ras, but Not N-Ras or K-Ras 4B, Proteinin Vivo [PDF]

open access: yesJournal of Biological Chemistry, 1998
Human cells contain four homologous Ras proteins, but it is unknown whether these homologues have different biological functions. As a first step in determining if Ras homologues might participate in distinct signaling cascades, we assessed whether a given Ras guanine nucleotide exchange factor could selectively activate a single Ras homologue in vivo.

Ras protein abundance correlates with Ras isoform mutation patterns in cancer [PDF]

open access: yesOncogene, 2021
Abstract Activating mutations of Ras genes are often observed in cancer. The protein products of the three Ras genes are almost identical. However, for reasons that remain unclear, KRAS is far more frequently mutated than the other Ras isoforms in cancer and RASopathies.

κB-Ras Proteins Regulate Both NF-κB-Dependent Inflammation and Ral-Dependent Proliferation

open access: yesCell Reports, 2014
The transformation of cells generally involves multiple genetic lesions that undermine control of both cell death and proliferation. We now report that κB-Ras proteins act as regulators of NF-κB and Ral pathways, which control inflammation/cell death and

Generation of specific antibodies against the rap1A, rap1B and rap2 small GTP-binding proteins. Analysis of rap and ras proteins in membranes from mammalian cells

open access: yes, 1992
Specific antibodies against rap1A and rap1B small GTP-binding proteins were generated by immunization of rabbits with peptides derived from the C-terminus of the processed proteins.

Role of PINCH and Its Partner Tumor Suppressor Rsu-1 in Regulating Liver Size and Tumorigenesis [PDF]

open access: yes, 2013
Particularly interesting new cysteine-histidine-rich protein (PINCH) protein is part of the ternary complex known as the IPP (integrin linked kinase (ILK)-PINCH-Parvin-α) complex.

Analysis of mutant Ras proteins [PDF]

open access: yesBiochemistry and Molecular Biology Education, 2007
AbstractTerms to be familiar with before you start to solve the test: growth‐factor signaling; Ras proteins; Raf proteins; G proteins; protein kinases; GTPase; GEFs (guanine nucleotide exchange factors); GAPs (GTPase activating proteins); transfection; expression plasmid; mitogen‐activated protein kinase (MAPK); extracellular signal‐regulated kinase ...

Mutated RAS Induced PLD1 Gene Expression through Increased Sp1 Trascription Factor [PDF]

open access: yes, 2009
2009-09The underlying mechanisms of oncogene-induced phospholipase D (PLD) activation have not been fully elucidated. The effect of the mutated-ras on PLD mRNA was examined using colon cancer cell lines as well as mock- and mutated ras-transfected NIH3T3

The Ins and Outs of RAS Effector Complexes

open access: yesBiomolecules, 2021
RAS oncogenes are among the most commonly mutated proteins in human cancers. They regulate a wide range of effector pathways that control cell proliferation, survival, differentiation, migration and metabolic status.
