CC   -!- FUNCTION: Actin-binding protein involved in motile and morphological
CC       processes. Inhibits actin polymerization, likely by sequestering G-
CC       actin. By capping the barbed ends of filaments, it also regulates
CC       motility. Seems to play an important role in clathrin-mediated
CC       endocytosis and distribution of endocytic organelles (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with G-actin; ADP-actin form and capping protein
CC       (CP). May also be able to interact with TWF2 and phosphoinositides,
CC       PI(4,5)P2. When bound to PI(4,5)P2, it is down-regulated. Interacts
CC       with ACTG1. {ECO:0000250|UniProtKB:Q12792,
CC       ECO:0000250|UniProtKB:Q91YR1}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton {ECO:0000250}.
CC       Note=Diffuse cytoplasmic localization with perinuclear and G-actin-rich
CC       cortical actin structures sublocalization. Also found at membrane
CC       ruffles and cell-cell contacts (By similarity). {ECO:0000250}.
CC   -!- PTM: Phosphorylated on serine and threonine residues. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the actin-binding proteins ADF family. Twinfilin
CC       subfamily. {ECO:0000305}.
