CC   -!- FUNCTION: Actin-binding protein involved in motile and morphological
CC       processes. Inhibits actin polymerization, likely by sequestering G-
CC       actin. Prevents actin filament assembly by forming a 1:1 complex with
CC       actin monomers, and inhibits the nucleotide exchange reaction of actin
CC       monomers (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with G-actin; ADP-actin form. {ECO:0000250}.
CC   -!- INTERACTION:
CC       P53250; P17555: SRV2; NbExp=3; IntAct=EBI-19663, EBI-4024;
CC       P53250; P68135: ACTA1; Xeno; NbExp=5; IntAct=EBI-19663, EBI-367540;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}.
CC   -!- MISCELLANEOUS: Present with 1470 molecules/cell in log phase SD medium.
CC       {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the actin-binding proteins ADF family. Twinfilin
CC       subfamily. {ECO:0000305}.
