Nucleo-Cytoplasmic Exchange

ID #1223

I just wanted to be sure about nucleo-cytoplasmic transport of mRNA molecules. Do the shuttle proteins that accompany the mRNA always need to be accompanied by importin/exportin themselves? They're not completely independent are they??

You're absolutely correct. Those "coating" proteins need to be recognized by exportin/importin to get where they're going. They are not independent movers. :)
