KRAS Ubiquitination at Lysine 104 Retains Exchange Factor Regulation by Dynamically Modulating the Conformation of the Interface

open access: yesiScience, 2020
Summary: RAS proteins function as highly regulated molecular switches that control cellular growth. In addition to regulatory proteins, RAS undergoes a number of posttranslational modifications (PTMs) that regulate its activity.

Targeting Oncogenic BRAF: Past, Present, and Future. [PDF]

open access: yes, 2019
Identifying recurrent somatic genetic alterations of, and dependency on, the kinase BRAF has enabled a "precision medicine" paradigm to diagnose and treat BRAF-driven tumors.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

Involvement of ras p2I in Neurotrophin-induced Response of Sensory, but Not Sympathetic Neurons [PDF]

open access: yes, 1993
Little is known about the signal transduction mechanisms involved in the response to neurotrophins and other neurotrophic factors in neurons, beyond the activation of the tyrosine kinase activity of the neurotrophin receptors belonging to the trk family.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

open access: yesMolecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Exploration of Aspergillus fumigatus Ras pathways for novel antifungal drug targets

open access: yesFrontiers in Microbiology, 2015
Ras pathway signaling is a critical virulence determinant for pathogenic fungi. Localization of Ras to the plasma membrane (PM) is required for Ras network interactions supporting fungal growth and virulence. For example, loss of A.

Membrane and Protein Interactions of the Pleckstrin Homology Domain Superfamily. [PDF]

open access: yes, 2015
The human genome encodes about 285 proteins that contain at least one annotated pleckstrin homology (PH) domain. As the first phosphoinositide binding module domain to be discovered, the PH domain recruits diverse protein architectures to cellular ...

Strength through diversity: how cancers thrive when clones cooperate

open access: yesMolecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

Ras signalling in pathogenic yeasts

open access: yesMicrobial Cell, 2017
The small GTPase Ras acts as a master regulator of growth, stress response and cell death in eukaryotic cells. The control of Ras activity is fundamental, as highlighted by the oncogenic properties of constitutive forms of Ras proteins.

Wirkung des Farnesyltransferaseinhibitors BZA-5B auf das Wachstum humaner Bronchialkarzinomzellen [PDF]

open access: yes, 2005
Ras-Mutationen werden in zirka 30% aller malignen Tumoren nachgewiesen. Es sind drei verschiedene ras-Gene bekannt, nämlich H-, K- und N-ras. Am häufigsten wird eine Mutation des K-ras-Gens nachgewiesen, dieses macht beim Bronchialkarzinom mehr als 95 ...
