Plays a role in the normal development of the peripheral and central nervous system (PubMed:11062474, PubMed:11159947, PubMed:16022285). Required for the correct localization of aurora kinase AURKA and the microtubule minus end-binding protein NUMA1 as well as a subset of AURKA targets which ensures proper spindle formation and timely chromosome alignment (PubMed:26246606). {ECO:0000269|PubMed:11062474, ECO:0000269|PubMed:11159947, ECO:0000269|PubMed:16022285, ECO:0000269|PubMed:26246606}. This is the function of AAAS (aladin WD repeat nucleoporin, ENSG00000094914).
