Note	The human Epidermal Growth Factor Receptor (EGFR) family is a family of receptor tyrosine kinases consisting of 4 members: EGFR, HER2, HER3 and HER4. These receptors are expressed on a wide variety of tissue types and have been implicated in many human cancers, including breast, gastric, colon and prostate. Strong expression of both HER3 and HER2 (also known as p185neu) by tumor cells can be associated with poor outcome for patients. The ligand for HER3 and HER4 is called Neu Differentiation Factor (NDF) or Heregulin. In some instances, antibodies against these receptors prove effective in combination therapy regimens for treatment of the disease. Signaling through the EGFR family involves the combinatorial dimerization of the four known family members and is mediated by at least 8 different hormones, including EGF and the heregulins. Heregulin binding and tyrosine phosphorylation by HER3 or HER4 is enhanced in the presence of HER2. Structurally the members of the EGFR family are 1210 to 1342 amino acids in length with approximately 650 amino acids of the extracellular domain being heavily glycosylated. The extracellular domains show up to 70% sequence homology.
