Drill-in on proteomics data. A Protein Viewer. Protein identifications and quantifications are listed in a tabular view. A threshold for five pre-computed false discovery rates can be set. Expression based custom filters (bottom) and custom queries based on calculated columns (top) allow the user to further browse the data. Data can be downloaded using the spreadsheet (Excel) export functionality. B Protein and peptides amino acid sequences. Clicking on the accession number in the protein viewer one is redirected to the Primary Protein and Peptides view. From there one can link to external database entries such as UniProt Knowledgebase or GenBank. C Quantification of UDP-glucose associated enzymes by MS analysis. Relative mean protein abundance values of UDP-glucose 6-dehydrogenase (UDG_STRP1) and UDP-glucose pyrophosphorylase (HASC1_STRP1) are plotted against five different treatment conditions.
