Finding nuclear localization signals.
A variety of nuclear localization signals (NLSs) are experimentally known although only one motif was available for database searches through PROSITE. We initially collected a set of 91 experimentally verified NLSs from the literature. Through iterated 'in silico mutagenesis' we then extended the set to 214 potential NLSs. This final set matched in 43% of all known nuclear proteins and in no kn...
متن کاملDimerization and a novel Tax speckled structure localization signal are required for Tax nuclear localization.
The human T-cell leukemia virus type 1 oncoprotein Tax has pleiotropic activities, a subset of which likely leads to immortalization of T cells. Tax is expressed and known to function in both the cell nucleus and the cytoplasm. Tax has defined nuclear localization (NLS) and nuclear export signals that enable shuttling between the two compartments. In this study, we identified a novel region in ...
متن کاملPrediction of Nuclear Localization Signals by HMM
The transport of nuclear proteins is a very important step for the maintenance of life. Most proteins that function in the nucleus are moved through the nuclear envelope that is penetrated by the nuclear pores. The nuclear pore is formed by a large, complex structure known as the nuclear pore complex (NPC). The NPC is a major gateway for mediating ions, small molecules, proteins, RNAs, and ribo...
متن کاملNLSdb: database of nuclear localization signals
NLSdb is a database of nuclear localization signals (NLSs) and of nuclear proteins. NLSs are short stretches of residues mediating transport of nuclear proteins into the nucleus. The database contains 114 experimentally determined NLSs that were obtained through an extensive literature search. Using 'in silico mutagenesis' this set was extended to 308 experimental and potential NLSs. This final...
متن کاملDimerization and nuclear localization of ku proteins.
Ku, a heterodimer of Ku70 and Ku80, plays a key role in multiple nuclear processes, e.g. DNA repair, chromosome maintenance, and transcription regulation. Heterodimerization is essential for Ku-dependent DNA repair in vivo, although its role is poorly understood. Some lines of evidence suggest that heterodimerization is required for the stabilization of Ku70 and Ku80. Here we show that the hete...
