[[Nucleoporin|Nucleoporins]] (NUP) are constituents of the nuclear pore complex which regulates the flow of macromolecules across the nuclear envelope. They are named according to their molecular weights. They contain a domain which binds the protein RAN (RANBD). The images at the left and at the right correspond to one representative Nucleoporin structure, ''i.e.'' crystal structure of yeast Nucleoporin NUP159 from ''Saccharomyces cerevisiae'' ([[1xip]]),
