Enables identical protein binding activity; kinetochore binding activity; and protein serine/threonine/tyrosine kinase activity. Involved in mitotic spindle assembly checkpoint signaling. Acts upstream of or within several processes, including meiotic spindle assembly checkpoint signaling; protein localization to organelle; and protein phosphorylation. Located in kinetochore. Is expressed in brain; lung; metanephros; and ureteric tip. Orthologous to human TTK (TTK protein kinase). [provided by Alliance of Genome Resources, Apr 2022]
