EGFR and infection: response (stress, intracellular transport of pathogen, cellular protein metabolic process, fibroblast growth factor stimulus), regulation (mRNA stability, epidermal growth factor receptor, transmembrane receptor protein serine/threonine kinase, establishment of planar polarity, intracellular signal transduction), modification of dependent macromolecule catabolic process, and small protein removal which are key functions during infection
