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. Essential component of cell cytoskeleton; plays an
CC       important role in cytoplasmic streaming, cell shape determination, cell
CC       division, organelle movement and extension growth.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC   -!- MISCELLANEOUS: There are at least 7 different actin genes in tobacco.
CC   -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
