The movement of proteins within the nucleus can occur by diffusion, with surprisingly extensive and rapid turnover occurring in high-affinity intranuclear compartments. The transport of the ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

Next, the researchers used two biologically active peptides ... translocate across the membrane, demonstrating protein transport. Peptides containing up to 50 amino acids could be inserted ...
