PPDB -- The Plant Proteomics Database at Cornell
What you can do:
Find proteomics information about Arabidopsis and maize.
Highlights:
- The Plant Proteomics Database provides an integrated resource for experimentally identified proteins in Arabidopsis and maize (Zea mays).
- Internal BLAST alignments link maize and Arabidopsis information.
- Experimental identification is based on in-house mass spectrometry (MS) of cell type-specific proteomes (maize), or specific subcellular proteomes (e.g. chloroplasts, thylakoids, nucleoids) and total leaf proteome samples (maize and Arabidopsis).
- More than 5000 accessions both in maize and Arabidopsis have been identified.
- More than 80 published Arabidopsis proteome datasets from subcellular compartments or organs are stored in PPDB and linked to each locus.
- Using MS-derived information and literature, more than 1500 Arabidopsis proteins have a manually assigned subcellular location, with a strong emphasis on plastid proteins.
- Additional new features of PPDB include searchable posttranslational modifications and searchable experimental proteotypic peptides and spectral count information for each identified accession based on in-house experiments.
- Various search methods are provided to extract more than 40 data types for each accession and to extract accessions for different functional categories or curated subcellular localizations.
- Protein report pages for each accession provide comprehensive overviews, including predicted protein properties, with hyperlinks to the most relevant databases.
- This database is distinct from PPDB, the plant promoter database.
