CC -!- FUNCTION: Actin is a highly conserved protein that polymerizes to
CC produce filaments that form cross-linked networks in the cytoplasm of
CC cells. Actin exists in both monomeric (G-actin) and polymeric (F-actin)
CC forms, both forms playing key functions, such as cell motility and
CC contraction. In addition to their role in the cytoplasmic cytoskeleton,
CC G- and F-actin also localize in the nucleus, and regulate gene
CC transcription and motility and repair of damaged DNA.
CC {ECO:0000250|UniProtKB:P60709}.
CC -!- SUBUNIT: Polymerization of globular actin (G-actin) leads to a
CC structural filament (F-actin) in the form of a two-stranded helix (By
CC similarity). Each actin can bind to 4 others (By similarity).
CC {ECO:0000250|UniProtKB:P60709, ECO:0000250|UniProtKB:P60710}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:P60710}. Nucleus {ECO:0000250|UniProtKB:O93400}.
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. {ECO:0000250|UniProtKB:P60710}.
CC -!- PTM: Methylation at His-73 by SETD3. Methylation stabilizes actin
CC filaments. {ECO:0000250|UniProtKB:P60706}.
CC -!- MISCELLANEOUS: In vertebrates 3 main groups of actin isoforms, alpha,
CC beta and gamma have been identified. The alpha actins are found in
CC muscle tissues and are a major constituent of the contractile
CC apparatus. The beta and gamma actins coexist in most cell types as
CC components of the cytoskeleton and as mediators of internal cell
CC motility. {ECO:0000250|UniProtKB:O93400}.
CC -!- SIMILARITY: Belongs to the actin family. {ECO:0000305}.
