Automated description from the Alliance of Genome Resources
Exhibits 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. Localizes to several cellular components, including the actin cytoskeleton; cytoplasm; and filopodium. Colocalizes with the ruffle membrane. Orthologous to human TWF1 (twinfilin actin binding protein 1).
