WebDec 23, 2024 · Myosin light chain kinase (MLCK), which induces contraction of the perijunctional apical actomyosin ring in response to the phosphorylation of the myosin light chain (MLC), gives rise to the opening of the paracellular pathways (Cunningham and Turner, 2012), thus playing a pivotal role in regulating TJ permeability. Therefore, it is not ... WebThe molecular basis for this interaction is the binding of myosin to actin filaments, allowing myosin to function as a motor that drives filament sliding. ... Tropomyosins (Fig. 2.1) Tropomyosins are contractile proteins which, together with the other proteins actin and myosin, function to regulate contraction in both muscle and non-muscle ...
