Abstract

(Figure presented.) Microtubule +TIP protein CKAP5 stabilizes CENP-E kinesin at the kinetochores and is essential for chromosome congression. CKAP5 depletion results in hyper-stable kinetochore-attached microtubules and increases recruitment of PP1, thereby causing CENP-E removal from kinetochores. CKAP5 stabilizes CENP-E at aligned kinetochores. CKAP5 depletion induces hyper-stability of kinetochore-attached microtubule. CKAP5 depletion promotes merotelic attachment errors. CKAP5 maintains optimum levels of PP1 on attached kinetochores. CKAP5 mediated regulation on PP1 and microtubule stability ensure CENP-E stabilization at kinetochores.
