Nuclear localization signal — A nuclear localizing sequence (NLS) is an amino acid sequence which acts like a tag on the exposed surface of a protein. This sequence is used to target the protein to the cell nucleus through the Nuclear Pore Complex and to direct a newly… … Wikipedia
Nuclear transport — The entry and exit of large molecules from the cell nucleus is tightly controlled by the nuclear pore complexes (NPCs). Although small molecules can enter the nucleus without regulation,[1] macromolecules such as RNA and proteins require… … Wikipedia
