Microtubule plus-end tracking protein that promotes the stabilization of dynamic microtubules during anaphase. Plays a crucial role in chromatin-induced microtubule formation. May also act at microtubule minus ends. May be involved in the nucleation of noncentrosomal microtubules originating from the trans-Golgi network (TGN) (By similarity). Interacts (via C-terminus) with clip1/clip-170, and cenpe. Localizes to microtubule plus ends. Associates with spindle microtubules, spindle poles, and kinetochores during metaphase, and shifts to the central spindle in late anaphase (By similarity). Belongs to the CLASP family.
