MSIPI is a database derived from IPI (International Protein Index) and contain additional information about cSNPs and N-terminal peptides (after removal of signal and transit peptides) in a format suitable for easy use in mass spectrometry search engines.  

Who made MSIPI
MSIPI is being produced in collaboration between:

• Department of Proteomics and Signaltransduction at the Max-Planck Institute for Biochemistry at Martinsried &
• CEBI at the University of Southern Denmark.

More details on MSIPI

The paper describing MSIPI has been published in Nature Methods: Schandorff S, Olsen JV, Bunkenborg J, Blagoev B, Zhang Y, Andersen JS, Mann M. A mass spectrometry-friendly database for cSNP identification.Nat Methods. 2007 Jun;4(6):465-6

Information on how the database is constructed and how to use MSIPI etc. is described in this paper

Where can I get MSIPI

• MSIPI databases are available from EBI in the directory ftp://ftp.ebi.ac.uk/pub/databases/IPI/msipi 
• For information on how to use msipi, please go to EBI and see http://www.ebi.ac.uk/IPI/msipi.html

            MSIPI is currently available for the species: Human and Mouse.
            MSIPI is available with and without decoy entries (reverse sequences - see Elias et al. 2005 Nature Methods)

Download the generating scripts

If you like to run the msipi setup at your own linux server, the scripts can be downloaded here: msipi.tar.gz
