Remodeling of the actin cytoskeleton is a dynamic and critical part of most cellular activities (e.g., cell shape, migration, proliferation, and survival). It is influenced by various signaling cascades that include G protein-coupled receptors (GPCRs), receptor tyrosine kinases (RTKs) and integrins. Actin can transition between two forms, monomeric and filamentous. This transition is highly regulated by a number of signaling, scaffolding and actin-binding proteins (ABPs). When actin remodeling malfunctions, it can result in various human diseases.
