nuclear pore complex
nuclear pore complex A complex that is formed from the nuclear pore (see NUCLEAR ENVELOPE) of a eukaryotic cell and the granular or fibrous annular material with which it is filled. The structure of the filling material, in particular, is still ill-defined, though it is thought to be a hollow cylinder. Its function is equally obscure, though probably it is concerned with regulating the transport of materials through the pores.
