The myosin X motor is optimized for movement on actin bundles

open access: yesNature Communications, 2016
Myosin X is a molecular motor unique in its ability to generate filopodia, but the mechanism explaining this behaviour is not known. Here, through a combination of structure, single-molecule assays and modelling the authors show that myosin X is ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Omecamtiv mecarbil and Mavacamten target the same myosin pocket despite opposite effects in heart contraction

open access: yesNature Communications
Inherited cardiomyopathies are common cardiac diseases worldwide, leading in the late stage to heart failure and death. The most promising treatments against these diseases are small molecules directly modulating the force produced by β-cardiac myosin ...

Esophageal High Pressure Zones: Effect of Perisophageal Structures on Esophageal Manometric Recording

open access: yesCanadian Journal of Gastroenterology, 1994
During the course of esophageal motility studies, short zones of elevated esophageal baseline pressure are occasionally noticed. The aim of this study is to determine their frequency and their cause. Among 77 consecutive esophageal manometries (group 1),

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

OY: Asian motility studies in irritable bowel syndrome

open access: yes, 2010
Altered motility remains one of the important pathophysiologic factors in patients with irritable bowel syndrome (IBS) who commonly complain of abdominal pain and stool changes such as diarrhea and constipation. The prevalence of IBS has in-creased among

Differences in the progression of liver disease in male and female rats induced by TAA: considerations in the development of pharmacological therapies

open access: yesAnnals of Hepatology
Introduction and Objectives: Thioacetamide (TAA) is a hepatotoxic agent that causes fibrosis, cirrhosis, and cancer. Various doses and regimens of TAA have been tested in different murine models to validate hepatoprotective compounds.

Prospecting the protein design landscape

open access: yesFEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Quantification of Cell Movement Reveals Distinct Edge Motility Types During Cell Spreading [PDF]

open access: yes, 2007
Actin-based motility is central to cellular processes such as migration, bacterial engulfment, and cancer metastasis, and requires precise spatial and temporal regulation of the cytoskeleton.
