Chaperone protein with functions in nuclear localization and cytoplasmic mRNA trafficking (PubMed:9376324, PubMed:26490864, PubMed:33602059). In postmitotic neurons, acts with nudE 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). Stabilizes PCID2 in the cytoplasm and thereby is required for promoting cytoplasmic mRNA trafficking (PubMed:33602059). Interacts with PCID2. Embryos (at protein level) (PubMed:33602059). Detected in embryos and adults (PubMed:9376324). 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 nudC family.
