WebMar 10, 2008 · On both RBCs and microbeads, human CD47 potently inhibits phagocytosis as does direct inhibition of myosin. CD47-SIRPalpha interaction initiates a dephosphorylation cascade directed in part at phosphotyrosine in myosin. A point mutation turns off this motor's contribution to phagocytosis, suggesting that self-recognition …
WebIn the sliding filament theory, myosin heads attach to an actin filament, bend to pull the actin filaments closer together, then release, reattach, and pull again. Energy from ATP is required for the myosin head to release from the actin filament—otherwise the myosin heads would remain in the same place, and the muscle would not contract. everything icedWebPlace the events of a contraction cycle in the order in which they occur. 1.ATP hydrolysis 2.Detachment of myosin head from actin 3.Power stroke 4.Crossbridge formation This problem has been solved!
