Predicted to enable protein serine/threonine kinase activator activity. Predicted to be involved in several processes, including meiotic spindle midzone assembly; metaphase plate congression; and positive regulation of protein serine/threonine kinase activity. Predicted to be located in several cellular components, including chromocenter; nuclear lumen; and pericentric heterochromatin. Predicted to be part of chromosome passenger complex. Predicted to be active in several cellular components, including kinetochore; meiotic spindle midzone; and midbody. Orthologous to human INCENP (inner centromere protein).
