Nuclear Export
A nuclear export signal (NES) is a short target peptide containing 4 hydrophobic residues in a protein that targets it for export from the cell nucleus to the cytoplasm through the nuclear pore complex using nuclear transport. It has the opposite effect of a nuclear localization signal, which targets a protein located in the cytoplasm for import to the nucleus. The NES is recognized and bound by exportins. NESs serve several vital cellular functions. They assist in regulating the position of proteins within the cell. Through this NESs affect transcription and several other nuclear functions that are essential to proper cell function. The export of many types of RNA from the nucleus is required for proper cellular function. The NES determines what type of pathway the varying types of RNA may use to exit the nucleus and perform their function and the NESs may effect the directionality of molecules exiting the nucleus. Structure Computer analysis of known NESs found the most common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
