Determining the calibration of confidence estimation procedures for unique peptides in shotgun proteomics.
The analysis of a shotgun proteomics experiment results in a list of peptide-spectrum matches (PSMs) in which each fragmentation spectrum has been matched to a peptide in a database. Subsequently, most protein inference algorithms rank peptides according to the best-scoring PSM for each peptide. However, there is disagreement in the scientific literature on the best method to assess the statist...

15 صفحه اولShotgun Proteomics in Neuroscience
Mass spectrometry-based proteomics is increasingly used to address basic and clinical questions in biomedical research through studies of differential protein expression, protein-protein interactions, and posttranslational modifications. The complex structural and functional organization of the human brain warrants the application of high-throughput, systematic approaches to understand the func...
متن کاملProteomic data mining using predicted peptide chromatographic retention times
Correct identification of proteins from peptide fragments is important for proteomic analyses. Peptides are initially separated by Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) before Mass Spectrometry (MS) identification. At the present time, peptide fragment retention (separation) time is not used as a useful scoring filter for identification of the peptide fragments and the...
