機能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.
組織特異性Expressed at high levels in the colon, testis, ovary, prostate and lung. Expressed at lower levels in the brain, bladder and heart. Not detected in liver.
配列類似性Belongs to the actin-binding proteins ADF family. Twinfilin subfamily. Contains 2 ADF-H domains.
翻訳後修飾Phosphorylated on serine and threonine residues.
細胞内局在Cytoplasm. Cytoplasm > cytoskeleton. Diffuse cytoplasmic localization with perinuclear and G-actin-rich cortical actin structures sublocalization. Also found at membrane ruffles and cell-cell contacts.
