PEAKS is a proteomics software program for tandem mass spectrometry designed for peptide sequencing, protein identification and quantification. ==Description== PEAKS is commonly used for peptide identification (Protein ID) through de novo peptide sequencing assisted search engine database searching.〔J. Zhang, L. Xin, B. Shan, W. Chen, M. Xie, D. Yuen, W. Zhang, Z. Zhang, G. Lajoie, and B. Ma. PEAKS DB: De Novo Sequencing Assisted Database Search for Sensitive and Accurate Peptide Identification. Molecular & Cellular Proteomics 10.1074/mcp.M111.010587 (2011).〕 PEAKS has also integrated PTM and mutation characterization through automatic peptide sequence tag based searching (SPIDER)〔Ma B, Johnson. De Novo sequencing and homology searching Molecular & Cellular Proteomics. 10.1074/mcp.O111.014902 (2011).〕 and PTM Identification.〔X. Han, L. He, L. Xin, B. Shan, B. Ma. PEAKS PTM: Mass Spectrometry Based Identification of Peptides with Unspecified Modifications. Journal of Proteomics Research 10(7): 2930-2936 (2011).〕 PEAKS provides a complete sequence for each peptide, confidence scores on individual amino acid assignments, simple reporting for high-throughput analysis, amongst other information. The software has the ability to compare results of multiple search engines. PEAKS inChorus will cross check test results automatically with other protein ID search engines, like Sequest, OMSSA, X!Tandem and Mascot. This approach guards against false positive peptide assignments. PEAKS Q is a plugin quantification tool, supporting label (ICAT, iTRAQ, SILAC, TMT, O18, etc.) and label free techniques.
