General Information

Term

nuclear pore cytoplasmic filaments

ID (Ontology)

GO:0044614 (Gene Ontology)

Definition

Filamentous extensions on cytoplasmic face of the nuclear pore complex (NPC). In S. cerevisiae, Nup159p, Nup82p, and Nup42p contribute to the cytoplasmic filaments. In vertebrates, Nup358 is a major component.[ PubMed:18046406 PubMed:19524430 PubMed:20947011 PubMed:22419078 ]

Also Known As

"cytoplasmic fibers of the NPC" ; "cytoplasmic fibers of the nuclear pore complex"
