Organism: latin (common) names for the nine organisms that contributed the most nuclear proteins (sorted by number of nuclear proteins) to NLSdb (together 7672 proteins in these nine organisms accounted for 91% of all currently known 8421 nuclear proteins); Number of nuclear proteins in NLSdb: gives the number of proteins annotated experimentally as nuclear and retained in NLSdb after applying a variety of filters (Methods); Proteins with NLS/NES: numbers and fractions (brackets) of the nuclear proteins that contain at least one NLS or NES from NLSdb.
