The epithelial cell cytoskeleton and intracellular trafficking. III. How is villin involved in the actin cytoskeleton dynamics in intestinal cells?
Villin plays a key role in the maintenance of the brush border organization by bundling F-actin into a network of parallel filaments. Our previous in vivo data on villin knockout mice showed that, although this protein is not necessary for the bundling of F-actin, it is important for the reorganization of the actin cytoskeleton elicited by stress conditions. We further investigated villin property to initiate actin remodeling in cellular processes such as hepatocyte growth factor-induced motility, morphogenesis, and bacterial infection. Our data suggest that villin is involved in actin remodeling necessary for many cellular processes requiring the actin cytoskeleton plasticity.
