WebJun 13, 2024 · One of the most notable clients of NPCs is a class of molecules known as messenger RNAs, or mRNAs. These are the messengers that carry genetic instructions from the nucleus to the cytoplasm, where they are then translated into proteins. But how the NPC transports the mRNAs out of the nucleus is still a mystery.
