Chaperone protein with functions in nuclear localization (PubMed:26490864). Required for centrosome duplication and formation and function of the mitotic spindle (By similarity). In postmitotic neurons, acts with nudC downstream of dar1 to ensure correct positioning of the nuclei in primary dendrites and as a consequence, is required for determining multipolar neuron morphology (PubMed:26490864). Localizes to the interphase centrosome and to the mitotic spindle. RNAi-mediated knockdown results in multipolar Class I dendritic arborizing neurons forming a bipolar morphology (PubMed:26490864). Dendritic arborization is unaffected (PubMed:26490864). Belongs to the nudE family.
