Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables actin monomer binding activity; phosphatidylinositol-4,5-bisphosphate binding activity; and protein tyrosine kinase activity. Involved in barbed-end actin filament capping; positive regulation of cardiac muscle hypertrophy; and sequestering of actin monomers. Located in several cellular components, including filopodium; myofibril; and perinuclear region of cytoplasm. Colocalizes with ruffle membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human TWF1 (twinfilin actin binding protein 1).
