A Systems Biology Approach to Emerging Respiratory Viral Diseases

This submission corresponds to peptides identified from proteomics analysis of tryptic digests of lung homogenates from C57Bl/6 mice infected with avian influenza (A/VN/1203/04). Mice were infected at 10e2, 10e3, or 10e4 pfu (n = 5 each) and sacrificed at 1, 2, 4, and 7 d post-infection. Aliquots of lung proteins were combined to create two pools corresponding to early (1 and 2 d post-infection) and late (4 and 7 d post-infection) infection and each pool was then subjected to tryptic digestion, followed by strong-cation exchange fractionation, resulting in 24 fractions each. Capillary LC-MS/MS analysis was then performed on each fraction. This submission corresponds to proteomics data collected from capillary LC-MS/MS analysis of the early infection pool. The MS/MS datasets were searched with SEQUEST using no enzyme search rules, and the peptide identification results were filtered using the following cutoffs; XCorr >= 1.6, 2.4, or 3.2 for 1+, 2+, or 3+ for fully tryptic peptides, and >= 4.3 or 4.7 for 2+ or 3+ partially tryptic or non-tryptic protein terminal peptides. Additionally, to reduce the total data size to a reasonable level, each spectrum was filtered to only include the top 100 most abundant ions in each 100 m/z-wide window. This submission is the aggregation of 24 individual LC-MS/MS analyses into one pseudo dataset.
