Protein Sorting - The models of Protein sorting (Aug/29/2006 )

Does anyone know anything on protein sorting? If so the mechanism by which sorting occurs in and out of the nucleus? Any respondance is greatly appreciated!

protein transport into the nucleus is governed by a nuclear localisation signal onthe terminus of the protein. this is recognised by the nuclear pore complex proteins on the nuclear envelope and the proterein is guided in through that. you'll find a lot more detail in molecular biology of the cell, bruce alberts et al.
