WebActin monomers associate with profilin which keeps them in an inactive form. Actin monomers are found inside organelles, whereas F-actin is found in the cytoplasm. Actin monomers associate with actin-binding proteins which prevent their interaction with F-actin. In humans, cell migration includes all of the following EXCEPT movement of: WebCofilin activity is negatively regulated by phosphorylation by the LIM kinase, which is activated by PAK, a direct effector of Rac1 and Cdc42. It was shown that Cdc42 inactivation and F-actin disappearance at the basis of the cup are directly correlated with and dependent on PI (4,5)P2 hydrolysis (Scott et al., 2005 ).
