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: Multiple isoforms are involved in various cellular functions
CC       such as cytoskeleton structure, cell mobility, chromosome movement and
CC       muscle contraction.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC   -!- PTM: Oxidation of Met-45 to form methionine sulfoxide promotes actin
CC       filament depolymerization. Methionine sulfoxide is produced
CC       stereospecifically, but it is not known whether the (S)-S-oxide or the
CC       (R)-S-oxide is produced (By similarity). {ECO:0000250}.
CC   -!- MISCELLANEOUS: There are at least 4 actin isoforms expressed during
CC       artemia development.
CC   -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
