What it does

This calls a Python re-implementation of the PredictNLS tool for prediction of nuclear localization signals (NLSs), which works by looking for matches to a known set of patterns (described using regular expressions).

The input is a FASTA file of protein sequences, and the output is tabular with these columns (multiple rows per protein):

Column	Description
1	Sequence identifier
2	Start of NLS
3	NLS sequence
4	NLS pattern (regular expression)
5	Number of reference proteins with this NLS
6	Percentage of reference proteins with this NLS which are nuclear localized
7	Comma separated list of reference proteins
8	Comma separated list of reference proteins' localizations

If a sequence has no predicted NLS, then there is no line in the output file for it. This is a simplification of the text rich output from the command line tool, to give a tabular file suitable for use within Galaxy.

Information about potential DNA binding (shown in the original predictnls tool) is not given.

Localizations

The following abbreviations are used (derived from SWISS-PROT):

Abbr	Localization
cyt	Cytoplasm
pla	Chloroplast
ret	Eendoplasmic reticululm
ext	Extracellular
gol	Golgi
lys	Lysosomal
mit	Mitochondria
nuc	Nuclear
oxi	Peroxisom
vac	Vacuolar
rip	Periplasmic
