Which of the following displaces Importin-alpha from the cargo transported inside the nucleus?

Which of the following displaces Importin-alpha from the cargo transported inside the nucleus? Correct Answer CAS

Once the complex composed of importin-alpha—importin-beta—molecule enters the nucleus, the importin-alpha and importin-beta has to be removed. RanGTP binds to Importin-beta and displaces it from the complex. Then the Cellular Apoptosis Susceptibility (CAS) protein which is an exportin and is bound to RanGTP, displaces Importin-alpha from the molecule with NLS sequence.
