      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P00533 # Isoform 2/truncated isoform may act as an antagonist.
      SIZE: 1210 amino acids; 134277 Da
      SUBUNIT: Binds RIPK1. CBL interacts with the autophosphorylated C- terminal tail of the EGF receptor. Part of a complex with ERBB2 and either PIK3C2A or PIK3C2B. The autophosphorylated form interacts with PIK3C2B, maybe indirectly. Interacts with PELP1.
      SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein. & Isoform 2: Secreted.
      TISSUE SPECIFICITY: Expressed in placenta. Isoform 2 is also expressed in ovarian cancers.
      PTM: Phosphorylation of Ser-695 is partial and occurs only if Thr- 693 is phosphorylated. & Monoubiquitinated and polyubiquitinated upon EGF stimulation; which does not affect tyrosine kinase activity or signaling capacity but may play a role in lysosomal targeting. Polyubiquitin linkage is mainly through 'Lys-63', but linkage through 'Lys-48', 'Lys-11' and 'Lys-29' also occur.DISEASE:SwissProt: P00533 # Defects in EGFR are associated with lung cancer [MIM:211980].
      SIMILARITY: SwissProt: P00533 ## Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily. & Contains 1 protein kinase domain.
      MISCELLANEOUS: Binding of EGF to the receptor leads to dimerization, internalization of the EGF-receptor complex, induction of the tyrosine kinase activity, stimulation of cell DNA synthesis, and cell proliferation.
