Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables actin monomer binding activity and phosphatidylinositol-4,5-bisphosphate binding activity. Involved in barbed-end actin filament capping and sequestering of actin monomers. Located in several cellular components, including lamellipodium; myofibril; and stereocilium. Is expressed in several structures, including ear; early embryo; genitourinary system; nervous system; and respiratory system. Orthologous to human TWF2 (twinfilin actin binding protein 2).
