CC   -!- SUBUNIT: Interacts with PFN1 and PFDN1. Does not interact with PFN2.
CC       {ECO:0000269|PubMed:16824795}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed in some hepatocellular carcinomas.
CC       {ECO:0000269|PubMed:16824795}.
CC   -!- PTM: Oxidation of Met-44 and Met-47 by MICALs (MICAL1, MICAL2 or
CC       MICAL3) to form methionine sulfoxide promotes actin filament
CC       depolymerization. MICAL1 and MICAL2 produce the (R)-S-oxide form. The
CC       (R)-S-oxide form is reverted by MSRB1 and MSRB2, which promote actin
CC       repolymerization (By similarity). {ECO:0000250}.
CC   -!- PTM: Monomethylation at Lys-84 (K84me1) regulates actin-myosin
CC       interaction and actomyosin-dependent processes. Demethylation by ALKBH4
CC       is required for maintaining actomyosin dynamics supporting normal
CC       cleavage furrow ingression during cytokinesis and cell migration.
CC   -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
CC   -!- CAUTION: Could be the product of a pseudogene. {ECO:0000305}.
