TargetP 1.1 Server

TargetP 1.1 predicts the subcellular location of eukaryotic proteins. The location assignment is based on the predicted presence of any of the N-terminal presequences: chloroplast transit peptide (cTP), mitochondrial targeting peptide (mTP) or secretory pathway signal peptide (SP).

For the sequences predicted to contain an N-terminal presequence a potential cleavage site can also be predicted.

NOTE 1:   TargetP uses ChloroP and SignalP to predict cleavage sites for cTP and SP, respectively.

NOTE 2:   The method has been tested on A. thaliana and H. sapiens sets; see the results.

New: the paper about using TargetP and other protein subcellular localization prediction methods:

Locating proteins in the cell using TargetP, SignalP, and related tools

PORTABLE VERSION

Would you prefer to run TargetP at your own site? TargetP 1.1 is available as a stand-alone software package, with the same functionality as the service above. Ready-to-ship packages exist for the most common UNIX platforms. There is a download page for academic users; other users are requested to contact CBS Software Package Manager at software@cbs.dtu.dk.
