ProMEX is a mass spectral library consisting of tryptic peptide product ion spectra generated by liquid chromatography coupled to ion trap mass spectrometry (LC-ITMS) and was developed using protein and phosphoprotein samples derived fromArabidopsis thaliana, Chlamydomonas reinhardtii, Medicago truncatula, Solanum tuberosum, Solanum lycopersicum L. and others. The database serves as a reference and can be used for protein identification in uncharacterized samples. Protein identification by ProMEX is linked to other molecular levels of biological organization such as metabolite, pathway and transcript data. Proteins are also linked to functional annotation in the UNIPROT knowledgebase. The database is further connected to annotation and classification services via BioMoby. For detailed information see publication.

MASC | Multinational Arabidopsis Steering Committe

The proteomics subcommittee of the Multinational Arabidopsis Steering Committee was established to facilitate the coordination of international research in Arabidopsis thaliana in the area of proteomics.

The throughput and accuracy of protein identification techniques relies strongly on the availability of whole genome sequences. The availability of both a complete genome sequence and high quality genome annotation makes Arabidopsis an ideal system to develop new proteomics technologies. Furthermore, Arabidopsis proteomics research can serve as a paradigm for other plant proteomics research projects and the advancement of plant proteomics in general. Finally, Arabidopsis proteomics enables the development of a unique platform for plant systems biology by integrating proteomics databases with existing transcriptomics and novel metabolomics and bioinformatics initiatives.
