Nuclear pore complex successfully mapped and diagramed

(Phys.org)—Two teams of researchers taking different approaches have successfully mapped and diagramed the nuclear pore complex (NPC)—protein complexes that make up the pores in the nuclear envelope that allow or prevent passage of molecules into the nucleus. One team from the California Institute of Technology took a bottom-up approach to discovering the makeup of the pore rings, while a team with members from several institutions in the U.S. and Germany took a top-down approach.
