Actin-binding protein involved in motile and morphological processes. Inhibits actin polymerization, likely by sequestering G-actin (By similarity). Interacts with G-actin; ADP-actin form and capping protein (CP). Perinuclear and G-actin-rich cortical actin structure sublocalization. Belongs to the actin-binding proteins ADF family. Twinfilin subfamily. Molecular embrace - Issue 73 of August 2006
