The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1
MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

Viral movement proteins (MPs) enable viral pathogens to pass through cell walls by increasing the size exclusion limit (SEL) of plasmodesmata (PD). Cucumber mosaic virus (CMV) MP was found to bind and sever actin filament (F-actin) in vitro, and such ...

Signaling in plants by intercellular RNA and protein movement [PDF]
Plants and animals have had about 1.6 billion years—the time that has passed since they diverged from their last unicellular ancestor—to evolve different mechanisms for solving unique problems of development and intercellular signaling. As an example, plant cells are separated from each other by a substantial extracellular matrix, the cell wall ...

This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Translation elongation can control translation initiation on eukaryotic mRNAs [PDF]
Synonymous codons encode the same amino acid, but differ in other biophysical properties. The evolutionary selection of codons whose properties are optimal for a cell generates the phenomenon of codon bias.

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

The Arabidopsis synaptotagmin SYTA regulates the cell-to-cell movement of diverse plant viruses
Synaptotagmins are a large gene family in animals that have been extensively characterized due to their role as calcium sensors to regulate synaptic vesicle exocytosis and endocytosis in neurons, and dense core vesicle exocytosis for hormone secretion ...

Elevated urine bis(monoacylglycerol)phosphate (BMP) levels have been found in gain-of-kinase function LRRK2 G2019S mutation carriers. Here, we have expanded urine BMP analysis to other Parkinson’s disease (PD) associated mutations and found them to be ...

Cellular Partners of Tobamoviral Movement Proteins
The size of viral genomes is limited, thus the majority of encoded proteins possess multiple functions. The main function of tobamoviral movement protein (MP) is to perform plasmodesmata gating and mediate intercellular transport of the viral RNA. MP is a remarkable example of a protein that, in addition to the initially discovered and most obvious ...

The 3a movement protein (MP) plays a central role in the movement ofBrome mosaic virus(BMV). To identify the functional regions in BMV MP, 24 alanine-scanning (AS) MP mutants of BMV were constructed. Infectivity of the AS mutants in the host plantChenopodium quinoashowed that the central region of BMV MP is important for viral movement and both termini
