A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

Molecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

CD13 regulation of membrane recycling: implications for cancer dissemination

Molecular & Cellular Oncology, 2019
Membrane recycling is critical to numerous cell functions and its dysregulation contributes to cancer and metastasis. We established that activation of the transmembrane molecule aminopeptidase N (ANPEP, also known as CD13) tethers the IQ motif ...

Exocytosis from permeabilized bovine adrenal chromaffin cells is differently modulated by guanosine 5'-[gamma-thio]triphosphate and guanosine 5'-[beta gamma-imido]triphosphate [PDF]

, 1992
1. In bovine adrenal chromaffin cells made permeable either to molecules less than or equal to 3 kDa with alphatoxin or to proteins less than or equal to 150 kDa with streptolysin O, the GTP analogues guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)

The T2238C human atrial natriuretic peptide molecular variant and the risk of cardiovascular diseases [PDF]

, 2018
Atrial natriuretic peptide (ANP) is a cardiac hormone which plays important functions to maintain cardio-renal homeostasis. The peptide structure is highly conserved among species. However, a few gene variants are known to fall within the human ANP gene.

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

Advanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Mechanical properties of tubulin intra- and inter-dimer interfaces and their implications for microtubule dynamic instability.

PLoS Computational Biology, 2019
Thirteen tubulin protofilaments, made of αβ-tubulin heterodimers, interact laterally to produce cytoskeletal microtubules. Microtubules exhibit the striking property of dynamic instability, manifested in their intermittent growth and shrinkage at both ...

NF-KB protein purification from bovine spleen: Nucleotide stimulation and binding site specificity [PDF]

, 1988
The activity of the enhancer for the κ immunoglobulin light chain gene critically depends on the presence in the nucleus of the NF-κB protein. We purified NF-κB over 50,000-fold and identified two protein species, 42 and 44 kDa, that could be eluted and ...

Cerebrospinal Fluid Metabolome in Central Nervous System Infections: A Study of Diagnostic Accuracy

Annals of Neurology, EarlyView.
Objective To assess the diagnostic accuracy of metabolites in cerebrospinal fluid (CSF) for central nervous system (CNS) infections. Methods Patients were derived from three prospective cohort studies in the Netherlands. All studies included adults suspected of a CNS infection who underwent a diagnostic lumbar puncture.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]

, 2002
Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

Structural Insights into the Regulation Mechanism of Small GTPases by GEFs

Molecules, 2019
Small GTPases are key regulators of cellular events, and their dysfunction causes many types of cancer. They serve as molecular switches by cycling between inactive guanosine diphosphate (GDP)-bound and active guanosine triphosphate (GTP)-bound states ...
