WebAbstract. Nuclear pore complexes (NPCs) are the gateways connecting the nucleoplasm and cytoplasm. This structures are composed of over 30 different proteins and 60–125 MDa of mass depending on type of species. NPCs are bilateral pathways that selectively control the passage of macromolecules into and out of the nucleus. WebNuclear pores, complex protein structures that span the double membrane of the nuclear envelope, serve as selective channels for the movement of macromolecules in and out of the nucleus. ...
