Purity > 90% as determined by SDS-PAGE. MW: 66.4kDa. Full Length: 1-349aa. N-terminal GST-tagged. Homo sapiens (Human). 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. May play a role in regulating the mature length of the middle and short rows of stereocilia
