4 maj 2007 — Aktin i muskeln bildar långa trådar som myosin- molekylerna kan dra i, eller vandra fram längs, säger Avhandlingen heter ”Actomyosin interactions on surfaces and guided actin filament transport for hybrid bionano devices”.

ATP is required to disrupt the myosin-actin interaction and prepare the system for another 'oar stroke.' Repetition of these oar-like myosin strokes constitutes a muscle contraction.

Actin myosin interaction

The binding of myosin to actin can be weak or strong. The affinity, which changes over 5 orders of magnitude, is controlled by ATP binding to the myosin head at a position remote from the actin binding site. ATP binding produces “weak binding.” In the absence of ATP the binding is “strong.” The free calcium ions will interfere with tropomyosin/troponin regulation of myosin/actin binding. This allows myosin to bind to actin.

lies in interactions between the contractile proteins myosin and actin. in the actin-myosin interaction mechanism with altered external load on the muscle. This book will appeal to research scientists seeking contemporary overviews of actin-myosin interaction and actin-based regulation.

Actin-myosin interactions play crucial roles in the generation of cellular force and movement. The molecular mechanism involves structural transitions at the interface between actin and myosin's catalytic domain, and within myosin's light chain domain, which contains binding sites for essential (ELC) and regulatory light chains (RLC).
