Nup153 Proteins and Enzymes

Nuclear pore complexes are extremely elaborate structures that mediate the regulated movement of macromolecules between the nucleus and cytoplasm. These complexes are composed of at least 100 different polypeptide subunits, many of which belong to the nucleoporin family. Nucleoporins are pore complex specific glycoproteins characterized by cytoplasmically oriented O linked N acetylglucosamine residues and numerous repeats of the pentapeptide sequence XFXFG. Nup153 has three distinct domains: a ...
