Required for nuclear migration to the bud neck during cell division. Targets cytoplasmic dynein to microtubule plus ends thereby promoting dynein-mediated microtubule sliding along the bud cortex and consequently the movement of the mitotic spindle to the bud neck. Self-associates. Interacts with PAC1. Also localizes to the plus ends of cytoplasmic microtubules, and this requires PAC1. Belongs to the nudE family.
