Single molecule mechanics resolves the earliest events in force generation by cardiac myosin

eLife, 2019
Key steps of cardiac mechanochemistry, including the force-generating working stroke and the release of phosphate (Pi), occur rapidly after myosin-actin attachment.

Type-I myosins promote actin polymerization to drive membrane bending in endocytosis

eLife, 2019
Clathrin-mediated endocytosis in budding yeast requires the formation of a dynamic actin network that produces the force to invaginate the plasma membrane against the intracellular turgor pressure.

THE MYOSIN FILAMENT [PDF]

The Journal of Cell Biology, 1972
The subunit organization of the myosin filament of chicken striated muscle has been observed directly in cross-sections in electron microscopy. The organization consists of three centrally located and nine peripherally located subunits in a close-packed arrangement.

Changes in Myosin from Silver Carp (Hypophthalmichthys molitrix) under Microwave-Assisted Water Bath Heating on a Multiscale

Foods, 2022
To further prove the advantages of microwave-assisted water bath heating (MWH) in low-value fish processing, the effects of different heating methods (two heating stage method, high temperature section respectively using MWH1, MWH2, MWH3, WH—water ...

Movement Asymmetries: From Their Molecular Origin to the Analysis of Movement Asymmetries in Athletes

Life, 2023
Asymmetry plays a major role in biology at all scales. This can be seen in the helix of DNA, the fact that the human heart is on the left side, or that most people use their right hand.

F-actin and myosin F control apicoplast elongation dynamics which drive apicoplast-centrosome association in Toxoplasma gondii

mBio, 2023
Toxoplasma gondii contains an essential plastid organelle called the apicoplast that is necessary for fatty acid, isoprenoid, and heme synthesis. Perturbations affecting apicoplast function or inheritance lead to parasite death.

In vivo movement of the type V myosin Myo52 requires dimerisation but is independent of the neck domain [PDF]

, 2007
Intracellular movement is a fundamental property of all cell types. Many organelles and molecules are actively transported throughout the cytoplasm by molecular motors, such as the dimeric type V myosins.

Quantum dot-based thermometry uncovers decreased myosin efficiency in an experimental intensive care unit model

Frontiers in Physiology
Critical illness myopathy (CIM) detrimentally affects muscle function in ICU patients, with a dramatic loss of muscle mass and function where the loss in specific force exceeds the loss in muscle mass (maximum force normalized to muscle cross-sectional ...

Estudo de mutações causadoras de cardiomiopatia hipertrófica em um grupo de pacientes no Espírito Santo, Brasil Estudio de mutaciones causadoras de cardiomiopatía hipertrófica en un grupo de pacientes en Espírito Santo, Brasil Study of mutations causing hypertrophic cardiomyopathy in a group of patients from Espirito Santo, Brazil

Arquivos Brasileiros de Cardiologia, 2010
FUNDAMENTO: A cardiomiopatia hipertrófica (CH) é a doença cardíaca hereditária mais frequente, causada por mutações nos genes codificadores para proteínas do sarcômero. Embora mais de 430 mutações tenham sido identificadas em vários continentes e países,

HLH-1 Modulates Muscle Proteostasis During Caenorhabditis elegans Larval Development

Frontiers in Cell and Developmental Biology, 2022
Muscle proteostasis is shaped by the myogenic transcription factor MyoD which regulates the expression of chaperones during muscle differentiation. Whether MyoD can also modulate chaperone expression in terminally differentiated muscle cells remains open.
