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.
CC   -!- FUNCTION: Essential component of cell cytoskeleton; plays an important
CC       role in cytoplasmic streaming, cell shape determination, cell division,
CC       organelle movement and extension growth.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC   -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
