Phosphoproteome: Enrichment of Gene Ontology (GO-) annotated kinase binding motifs in significantly regulated phosphopeptides identified via LC-MS/MS analysis. Kinases binding to binding motifs enriched within the peptides with significantly increased phosphorylation were analyzed using the group-based prediction system 3.0 (http://gps.biocuckoo.org/).
