Prediction of leucine-rich nuclear export signal containing proteins with NESsential
The classical nuclear export signal (NES), also known as the leucine-rich NES, is a protein localization signal often involved in important processes such as signal transduction and cell cycle regulation. Although 15 years has passed since its discovery, limited structural information and high sequence diversity have hampered understanding of the NES. Several consensus sequences have been propo...
متن کاملAnalysis and prediction of leucine-rich nuclear export signals.
We present a thorough analysis of nuclear export signals and a prediction server, which we have made publicly available. The machine learning prediction method is a significant improvement over the generally used consensus patterns. Nuclear export signals (NESs) are extremely important regulators of the subcellular location of proteins. This regulation has an impact on transcription and other n...
متن کاملValidNESs: a database of validated leucine-rich nuclear export signals
ValidNESs (http://validness.ym.edu.tw/) is a new database for experimentally validated leucine-rich nuclear export signal (NES)-containing proteins. The therapeutic potential of the chromosomal region maintenance 1 (CRM1)-mediated nuclear export pathway and disease relevance of its cargo proteins has gained recognition in recent years. Unfortunately, only about one-third of known CRM1 cargo pro...
متن کاملNESmapper: Accurate Prediction of Leucine-Rich Nuclear Export Signals Using Activity-Based Profiles
The nuclear export of proteins is regulated largely through the exportin/CRM1 pathway, which involves the specific recognition of leucine-rich nuclear export signals (NESs) in the cargo proteins, and modulates nuclear-cytoplasmic protein shuttling by antagonizing the nuclear import activity mediated by importins and the nuclear import signal (NLS). Although the prediction of NESs can help to de...
متن کاملCRM1 Is an Export Receptor for Leucine-Rich Nuclear Export Signals
CRM1 is distantly related to receptors that mediate nuclear protein import and was previously shown to interact with the nuclear pore complex. Overexpression of CRM1 in Xenopus oocytes stimulates Rev and U snRNA export from the nucleus. Conversely, leptomycin B, a cytotoxin that is shown to bind to CRM1 protein, specifically inhibits the nuclear export of Rev and U snRNAs. In vitro, CRM1 forms ...
