Origins of DNA replication that function in eukaryotic cells.

abstract：:Although it is universally accepted that protein synthesis occurs in the cytoplasm, the possibility that translation can also take place in the nucleus has been hotly debated. Reports have been published claiming to demonstrate nuclear translation, but alternative explanations for these results have not been excluded,...

abstract：:The assembly of intermediate filament (IF) arrays involves the recruitment of a complex set of cell-type-specific IF-associated proteins. Some of them are integral membrane proteins, others act as crosslinking proteins with vectorial binding activities, and yet others comprise motor proteins. In vivo IFs appear to be ...
