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.

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 ...

PIK3CB and K-ras in oral squamous Cell carcinoma. A possible cross-talk!

open access: yesJournal of Orofacial Sciences, 2014
Background: PIK3 and K-ras are signal transducing proteins involved and mediating many responses related to cell cycle growth regulation. Until date, there has been only limited evidence about the expression of K-ras and PKI3CB in oral squamous cell ...

Evaluating The Role Of Nitric Oxide Synthase In Oncogenic Ras-Driven Tumorigenesis

open access: yesRedox Biology, 2015
We previously reported that oncogenic KRAS activation of the PI3K/AKT pathway stimulates the remaining wild-type HRAS and NRAS proteins in a manner dependent upon both eNOS expression and C118 in HRAS and NRAS, which promoted tumor growth.

Membrane interactions of the globular domain and the hypervariable region of KRAS4b define its unique diffusion behavior

open access: yeseLife, 2020
The RAS proteins are GTP-dependent switches that regulate signaling pathways and are frequently mutated in cancer. RAS proteins concentrate in the plasma membrane via lipid-tethers and hypervariable region side-chain interactions in distinct nano-domains.

RAS-inhibiting biologics identify and probe druggable pockets including an SII-α3 allosteric site

open access: yesNature Communications, 2021
Oncogenic RAS mutants remain difficult to target with small molecules. Here, the authors show that RAS-binding Affimer proteins inhibit RAS signaling while binding diverse regions on the RAS surface, suggesting the potential to use Affimers as tools to ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Deconstruction of the Ras switching cycle through saturation mutagenesis

open access: yeseLife, 2017
Ras proteins are highly conserved signaling molecules that exhibit regulated, nucleotide-dependent switching between active and inactive states. The high conservation of Ras requires mechanistic explanation, especially given the general mutational ...
