Any cellular process that depends upon or alters the actin cytoskeleton, that part of the cytoskeleton comprising actin filaments and their associated proteins. The directed movement of substances along cytoskeletal elements such as microfilaments or microtubules within a cell. Movement of organelles or other particles along actin filaments, or sliding of actin filaments past each other, mediated by motor proteins. The actin filament-based process by which cytoplasmic actin filaments slide past one another resulting in contraction of all or part of the cell body. The sliding of actin thin filaments and myosin thick filaments past each other in muscle contraction. This involves a process of interaction of myosin located on a thick filament with actin located on a thin filament. During this process ATP is split and forces are generated. The sliding movement of actin thin filaments and myosin thick filaments past each other.
