How plants maintain this precise positioning is unclear. Myosin XI is a plant-specific motor protein that moves along actin filaments and helps in intracellular organelle transport.

Actin is a globular protein that is a major constituent of the cellular cytoskeleton. Actin can exist in monomeric form as G-actin (globular actin) or can form filaments (F-actin, filamentous ...

Japan's GDP in Q1 2025 was flat, a better performance than the initial 0.2% contraction estimate, though significantly slower than Q4's 0.6% growth. Net trade surprisingly boosted GDP by 0.4 ...

Smooth muscle cells maintain filaments of actin and myosin in the presence of ATP, although dephosphorylated myosin filaments and actin–myosin interactions are unstable under those conditions in vitro ...

Myosin II, like many molecular motors, is a two-headed dimer held together by a coiled-coil rod. The stability of the (S2) rod has implications for head−head interactions, force generation, and ...
