A tool to support article selection and information extraction of functional impact of phosphorylated proteins. The current version focuses on protein-protein interactions (PPIs) as functional impact. In eFIP, PPIs refer to interactions between protein elements, including protein complexes and classes of proteins. Impact is defined as any direct relation between protein phosphorylation and PPI. The relation could be positive (phosphorylation of A increases binding to B), negative (when phosphorylated A dissociates from B) or neutral (phosphorylated A binds B).
