General annotation (Comments)

Function

Actin-binding protein involved in motile and morphological processes. Inhibits actin polymerization, likely by sequestering G-actin. By capping the barbed ends of filaments, it also regulates motility. Seems to play an important role in clathrin-mediated endocytosis and distribution of endocytic organelles By similarity.

Subunit structure

Interacts with G-actin; ADP-actin form and capping protein (CP). May also be able to interact with TWF2 and phosphoinositides, PI(4,5)P2. When bound to PI(4,5)P2, it is down-regulated By similarity.

Subcellular location

Cytoplasm. Cytoplasm › cytoskeleton By similarity. Note: Diffuse cytoplasmic localization with perinuclear and G-actin-rich cortical actin structures sublocalization. Also found at membrane ruffles and cell-cell contacts By similarity.

Post-translational modification

Phosphorylated on serine and threonine residues By similarity.

Sequence similarities

Belongs to the actin-binding proteins ADF family. Twinfilin subfamily.

Contains 2 ADF-H domains.
