Component of the nuclear pore complex. During mitosis diffusively localized throughout the cytoplasm. Expressed in adult male accessory glands (at protein level). Expressed in embryos and third instar larvae (at protein level) (PubMed:3919018, PubMed:2517292, PubMed:7641726). Levels are highest during embryogenesis, decrease through larval stages, and finally increase during pupation and adult stages (PubMed:7641726). Glycosylated. Belongs to the NUP210 family.
