hey,
It's as the title says: what's the reason that the inner nuclear membrane and the outer nuclear membrane (separated by the perinuclear space) have a different protein composition? while it is actually a continuous layer...
The only reasons i can think of is: protein synthesis only occurs on the outer membrane since it is the continuation of the rer or that perhaps the nuclear pore complex form a barrier between the outer and inner membrane.
Can someone help me out here...
Thanks in advance!
