Movement of Lipid Droplets in the Arabidopsis Pollen Tube Is Dependent on the Actomyosin System
Plants, 2023 The growth of pollen tubes, which depends on actin filaments, is pivotal for plant reproduction. Pharmacological experiments showed that while oryzalin and brefeldin A treatments had no significant effect on the lipid droplets (LDs) trafficking, while 2 ...

Discovery of the first unconventional myosin: Acanthamoeba myosin-I
Frontiers in Physiology, 2023 Having characterized actin from Acanthamoeba castellanii (Weihing and Korn, Biochemistry, 1971, 10, 590–600) and knowing that myosin had been isolated from the slime mold Physarum (Hatano and Tazawa, Biochim. Biophys.

Competition between myosin II and βH-spectrin regulates cytoskeletal tension
eLife, 2023 Spectrins are membrane cytoskeletal proteins generally thought to function as heterotetramers comprising two α-spectrins and two β-spectrins. They influence cell shape and Hippo signaling, but the mechanism by which they influence Hippo signaling has ...

Cells, 2020 The MYH9 gene encodes the heavy chain (MHCII) of non-muscle myosin II A (NMII-A). This is an actin-binding molecular motor essential for development that participates in many crucial cellular processes such as adhesion, cell migration, cytokinesis and ...

Single-molecule imaging reveals the concerted release of myosin from regulated thin filaments
eLife, 2021 Regulated thin filaments (RTFs) tightly control striated muscle contraction through calcium binding to troponin, which enables tropomyosin to expose myosin-binding sites on actin. Myosin binding holds tropomyosin in an open position, exposing more myosin-

Stay in Touch—The Cortical ER of Moss Protonemata in Osmotic Stress Situations
Plants, 2020 Plasmolysis is usually introduced to cell biology students as a tool to illustrate the plasma membrane: hypertonic solutions cause the living protoplast to shrink by osmotic water loss; hence, it detaches from the surrounding cell wall.
