Enables several functions, including myosin V binding activity; protein C-terminus binding activity; and protein serine/threonine kinase activator activity. Involved in protein autophosphorylation; regulation of actin cytoskeleton organization; and regulation of microtubule cytoskeleton organization. Predicted to be located in microtubule cytoskeleton and perinuclear region of cytoplasm. Predicted to be active in cytoplasm. Orthologous to human TAOK1 (TAO kinase 1).
