Enables epidermal growth factor binding activity and epidermal growth factor-activated receptor activity. Involved in cellular response to amino acid stimulus and positive regulation of fibroblast proliferation. Acts upstream of or within several processes, including animal organ development; epidermal growth factor receptor signaling pathway; and protein autophosphorylation. Located in several cellular components, including basolateral plasma membrane; endocytic vesicle; and perinuclear region of cytoplasm. Is expressed in several structures, including alimentary system; brain; integumental system; limb; and respiratory system. Used to study Coronavirus infectious disease and aortic valve disease. Human ortholog(s) of this gene implicated in several diseases, including colorectal cancer; lung non-small cell carcinoma (multiple); pancreatic cancer; prostate cancer; and pulmonary tuberculosis. Orthologous to human EGFR (epidermal growth factor receptor). [provided by Alliance of Genome Resources, Apr 2022]
