Question

roles of various proteins in movement of molecules across nuclear pore complex​

Answer 1

Answer:

Nuclear pore complexes are large aqueous channels that penetrate the nuclear envelope, connecting the nuclear interior with the cytoplasm. Until recently, these macromolecular complexes were viewed as static structures whose only function was to control the molecular trafficking between the two compartments.

All transport between the nucleus and the cytoplasm occurs through large protein channels that are embedded in the nuclear membrane. These channels, which are called nuclear pore complexes (NPCs), are composed of proteins referred to as nucleoporins.

Answer 2

Nucleoporins are a family of proteins which are the constituent building blocks of the nuclear pore complex (NPC).

Nuclear pores enable the passive and facilitated transport of molecules across the nuclear envelope.

Nucleoporins are able to transport molecules across the nuclear envelope at a very high rate. A single NPC is able to transport 60,000 protein molecules across the nuclear envelope every minute.
