However, due to the inherent complexity of phosphorylation patterns and the lack of knowledge on how phosphorylations are related to functions, it is often not possible to directly deduce protein activities from those measurements. Here, we present a heuristic machine learning algorithm that infers the activities of kinases from Phosphoproteomics data using kinase\u2013target information from the PhosphoSitePlus database. By comparing the estimated kinase activity profiles to the measured phosphosite profiles, it is furthermore possible to derive the kinases that are most likely to phosphorylate the respective phosphosite.<\/jats:p>\n               <jats:p>Results: We apply our approach to published datasets of the human cell cycle generated from HeLaS3 cells, and insulin signalling dynamics in mouse hepatocytes. In the first case, we estimate the activities of 118 at six cell cycle stages and derive 94 new kinase\u2013phosphosite links that can be validated through either database or motif information. In the second case, the activities of 143 kinases at eight time points are estimated and 49 new kinase\u2013target links are derived.<\/jats:p>\n               <jats:p>Availability and implementation: The algorithm is implemented in Matlab and be downloaded from github. It makes use of the Optimization and Statistics toolboxes. https:\/\/github.com\/marcel-mischnik\/IKAP.git.<\/jats:p>\n               <jats:p>Contact: \u00a0marcel.mischnik@gmail.com<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btv699","type":"journal-article","created":{"date-parts":[[2015,12,2]],"date-time":"2015-12-02T01:38:53Z","timestamp":1449020333000},"page":"424-431","source":"Crossref","is-referenced-by-count":76,"title":["IKAP: A heuristic framework for inference of kinase activities from Phosphoproteomics data"],"prefix":"10.1093","volume":"32","author":[{"given":"Marcel","family":"Mischnik","sequence":"first","affiliation":[{"name":"1 Sanofi-Aventis Deutschland GmbH, Frankfurt, Germany and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Sacco","sequence":"additional","affiliation":[{"name":"2 Department of Proteomics and Signal Transduction, Max-Planck-Institute for Biochemistry, Martinsried, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00fcrgen","family":"Cox","sequence":"additional","affiliation":[{"name":"2 Department of Proteomics and Signal Transduction, Max-Planck-Institute for Biochemistry, Martinsried, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans-Christoph","family":"Schneider","sequence":"additional","affiliation":[{"name":"1 Sanofi-Aventis Deutschland GmbH, Frankfurt, Germany and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Sch\u00e4fer","sequence":"additional","affiliation":[{"name":"1 Sanofi-Aventis Deutschland GmbH, Frankfurt, Germany and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manfred","family":"Hendlich","sequence":"additional","affiliation":[{"name":"1 Sanofi-Aventis Deutschland GmbH, Frankfurt, Germany and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Crowther","sequence":"additional","affiliation":[{"name":"1 Sanofi-Aventis Deutschland GmbH, Frankfurt, Germany and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Mann","sequence":"additional","affiliation":[{"name":"2 Department of Proteomics and Signal Transduction, Max-Planck-Institute for Biochemistry, Martinsried, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Klabunde","sequence":"additional","affiliation":[{"name":"1 Sanofi-Aventis Deutschland GmbH, Frankfurt, Germany and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2015,12,1]]},"reference":[{"key":"2023020110312732100_btv699-B1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1007\/978-1-60761-175-2_1","article-title":"Mining protein-protein interactions from published literature using Linguamatics I2E","volume":"563","author":"Bandy","year":"2009","journal-title":"Methods Mol.
