CC -!- FUNCTION: Actin-binding protein involved in motile and morphological
CC processes. Inhibits actin polymerization, likely by sequestering G-
CC actin (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with G-actin; ADP-actin form and capping protein
CC (CP). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}. Cytoplasm,
CC perinuclear region {ECO:0000250}. Note=Perinuclear and G-actin-rich
CC cortical actin structure sublocalization. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the actin-binding proteins ADF family. Twinfilin
CC subfamily. {ECO:0000305}.
