CC   -!- FUNCTION: Actins are highly conserved proteins that are involved in
CC       various types of cell motility and are ubiquitously expressed in all
CC       eukaryotic cells. Multiple isoforms are involved in various cellular
CC       functions such as cytoskeleton structure, cell mobility, chromosome
CC       movement and muscle contraction (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
