  16. Chapter 12 Intracellular Compartments and Protein Sorting

  17. Major Intracellular compartments of an animal cell

  18. Volumes of major intracellular compartments in a liver cell

  19. Relative amount of membrane types in 2 cell types

  20. Complex Cortical Network of Endoplasmic Reticulum

  21. Cross section of liver cell

  22. Topological relationships between compartments of a eukaryotic cell

  23. Roadmap of protein traffic inside cell

  24. Two ways in which a sorting signal can bebuilt into a protein

  25. Some typical signal sequences

  26. Nuclear Pore complexes perforate the nuclear envelope

  27. Nuclear pore complexes

  28. Nuclear side of the nuclear envelope

  29. Face on view of nuclear complexes without the membrane

  30. Side view of 2 nuclear pore complexes

  31. Transport through nuclear pore complexes occurs through free diffusion and active transport

  32. Nuclear import signal direst proteins to the nucleus

  33. Single amino acid mutation in signal will prevent import into the nucleus

  34. Nuclear import receptors bind to nuclear porins and nuclear localization signal of cargo protein Different nuclear localization signals bind different import receptors
