PickPocket 1.1 Server

PickPocket server predicts binding of peptides to any known MHC molecule using positiion specific weight matrices. The method is trained on more than 150,000 quantitative binding data covering more than 150 different MHC molecules. Predictions can be made for HLA-A, B, C, E and G alleles, as well as for non-human primates, mouse, Cattle and pig. Further, the user can upload full length MHC protein sequences, and have the server predict MHC restricted peptides from any given protein of interest.

Version 1.1 has been retrained on extented data set including 10 prevalent HLA-C and 7 prevalent BoLA MHC-I molecules.

The PSWM's are generated using the SMM_pmbec method described in 19948066

Predictions can be made for 8-12 mer peptides. Note, that all non 9mer predictions are made using approximations. Most HLA molecules have a strong preference for binding 9mers.

The prediction values are given in nM IC50 values.

The project is a collaboration between CBS, IMMI, and LIAI.

As of July 8th, the nomenclature for BoLA-I has been updated to follow IPD Release 1.3.

PORTABLE VERSION

Would you prefer to run PickPocket at your own site? PickPocket v. 1.1 is available as a stand-alone software package, with the same functionality as the service above. Ready-to-ship packages exist for Linux and Darwin (MacOSX). There is a download page for academic users; other users are requested to contact CBS Software Package Manager at software@cbs.dtu.dk.
