RAS-targeted therapies: is the undruggable drugged?

AR Moore, SC Rosenberg, F McCormick… - Nature reviews Drug …, 2020 - nature.com
Abstract RAS (KRAS, NRAS and HRAS) is the most frequently mutated gene family in
cancers, and, consequently, investigators have sought an effective RAS inhibitor for more …

A model for RAS mutation patterns in cancers: finding the sweet spot

S Li, A Balmain, CM Counter - Nature Reviews Cancer, 2018 - nature.com
The three RAS genes—HRAS, NRAS and KRAS—are collectively mutated in one-third of
human cancers, where they act as prototypic oncogenes. Interestingly, there are rather …

Consensus on the RAS dimerization hypothesis: Strong evidence for lipid-mediated clustering but not for G-domain-mediated interactions

DK Simanshu, MR Philips, JF Hancock - Molecular cell, 2023 - cell.com
One of the open questions in RAS biology is the existence of RAS dimers and their role in
RAF dimerization and activation. The idea of RAS dimers arose from the discovery that RAF …

Machine learning-driven multiscale modeling: bridging the scales with a next-generation simulation infrastructure

HI Ingólfsson, H Bhatia, F Aydin… - Journal of Chemical …, 2023 - ACS Publications
Interdependence across time and length scales is common in biology, where atomic
interactions can impact larger-scale phenomenon. Such dependence is especially true for a …

Machine learning–driven multiscale modeling reveals lipid-dependent dynamics of RAS signaling proteins

HI Ingólfsson, C Neale, TS Carpenter… - Proceedings of the …, 2022 - National Acad Sciences
RAS is a signaling protein associated with the cell membrane that is mutated in up to 30% of
human cancers. RAS signaling has been proposed to be regulated by dynamic …

[HTML][HTML] Therapeutic targeting of RAS: New hope for drugging the “undruggable”

A structural model of a Ras–Raf signalosome

VP Mysore, ZW Zhou, C Ambrogio, L Li… - Nature structural & …, 2021 - nature.com
The protein K-Ras functions as a molecular switch in signaling pathways regulating cell
growth. In the human mitogen-activated protein kinase (MAPK) pathway, which is implicated …

Two distinct structures of membrane‐associated homodimers of GTP‐and GDP‐bound KRAS4B revealed by paramagnetic relaxation enhancement

KY Lee, Z Fang, M Enomoto… - Angewandte Chemie …, 2020 - Wiley Online Library
KRAS homo‐dimerization has been implicated in the activation of RAF kinases, however,
the mechanism and structural basis remain elusive. We developed a system to study KRAS …

KRAS-specific inhibition using a DARPin binding to a site in the allosteric lobe

N Bery, S Legg, J Debreczeni, J Breed… - Nature …, 2019 - nature.com
Inhibiting the RAS oncogenic protein has largely been through targeting the switch regions
that interact with signalling effector proteins. Here, we report designed ankyrin repeat …

Raf promotes dimerization of the Ras G-domain with increased allosteric connections

MR Packer, JA Parker, JK Chung, Z Li… - Proceedings of the …, 2021 - National Acad Sciences
Ras dimerization is critical for Raf activation. Here we show that the Ras binding domain of
Raf (Raf-RBD) induces robust Ras dimerization at low surface densities on supported lipid …
