What would a decrease in the cytoplasmic concentration of ca

What would a decrease in the cytoplasmic concentration of capping protein in a motile cell have on the morphology of the actin meshwork?

How would these changes effect the shape of the cellular structures for motility?

What other actin regulatory activities would enhance this morphological effect?

Solution

Polymers of actin are Microfilaments. That help with cell shape( because it bears tension in the cell) & cell motility.

Polymerization of actin monomers forms Microfilaments , by a process fueled by ATP hydrolysis, that forms the chains of filamentous actin. Microfilaments are dynamic structures, shrinks and grows in a controlled way. some of microfilaments play a structrual role to maintain cell shape in the cell.protein caps at both ends of These structural microfilaments is to prevent changes in microfilament length. some other microfilaments have functions that require dynamic changes in length. cytoplasmic streaming,that is a mixing of the cytoplasm that aids diffusion is also been mediated by Microfilaments .
