The sliding filament model can describe both how vesicles are moved through a cell as well as locomotion. How can two different processes use the same underlying mechanism? Explain how actin organization differs to allow for these two different processes.
since both of the structures are composed of contractie unit actin so one mechanism can explain both the processes.Vesicles move by microfilament as well as microtubule.We explain the movement by microfilament composed of actin.
in locomotion the contractile unit is the sacrcomere which consists of actin and myosin.
Actin in sarcomere is sandwiched between myosin filament.
Vesicles organize their own actin tracks by recruiting the actin nucleation factors Spire1, Spire2 and Formin-2, which assemble an extensive actin network from the vesicles’ surfaces. The network connects the vesicles with each other and with the plasma membrane.
