2020 — Yu, L., Grenklo, S., and Karlsson, R. (2008) The Profilin:Actin complex Characterization of the interaction with myosin and tropomyosin. Abstract : Background and Aims: Muscle contraction involves cross-bridge interaction between actin and myosin filaments, which is regulated by variations of  β1-positive/vinculin-positive focal adhesions, and reduced junctional association of actin–myosin II. In vitro assays reveal that β1 integrin-mediated interaction  Items 121 - 140 of 247 — Transcriptional regulation of ribosomal RNA gene : actin, myosin and Interaction of the genome maintenance proteins of oncogeneic  18 juli 2019 — Intensiteten av myosin skikt linjer är nära besläktad med graden av beställning medan Actin-baserade lager linjer är mer framträdande i mönster från thin filament and augments cross-bridge interaction in skeletal muscle. This kinase phosphorylates myosin regulatory light chains to facilitate myosin interaction with actin filaments to produce contractile activity. This gene encodes​  Cardiotonic bipyridine amrinone slows myosin-induced actin filament sliding at for real time monitoring of antithrombin interactions with immobilized heparin.

Actin myosin interaction

Spheres show the donor (D) and acceptor (A) labeling sites on actin (C374, grey), on myosin (C16, green), and the HCM actin and myosin interaction 1.

As can be observed, actin binding is mediated by residues in the upper and lower subdomain cleft. Residues 335-372 in an actin monomer of the filament show the most extensive contact with these loops. In muscles, projections on the myosin filaments, the so-called myosin heads or cross-bridges, interact with the nearby actin filaments and, in a mechanism powered by ATP-hydrolysis, they move the actin filaments past them in a kind of cyclic rowing action to produce the macroscopic muscular movements of which we are all aware. In vitro motility assay: Sheetz and Spudich (1983) have introduced the in vitro motility assay for studying actin-myosin interaction at the molecular level. In the motility assay either myosin-coated fluorescent beads are observed moving unidirectionally along organized actin filament arrays or single fluorescent-labeled actin filaments are visualized moving over a myosin-coated surface.
