WebThe nuclear pore complex (NPC) is composed of ∼30 unique proteins, collectively referred to as nucleoporins or Nups. While metazoan Nups are known to be phosphorylated during mitosis to cause disassembly of the NPC, what is less clear is whether Nups are phosphorylated and regulated by extracellular stimuli in interphase cells. WebProteins enter the nucleus through the nuclear pore complex. Once in the nucleus, some proteins, such as transcriptional regulators, can turn genes on or off, and change the composition of the cell and its function to meet the demands of its environment.
