Signaling Pathways

ErbB/HER Signaling

The ErbB receptor tyrosine kinase family has four cell surface receptors: ErbB1/EGFR/HER1, ErbB2/HER2, ErbB3/HER3, and ErbB4/HER4. ErbB receptors signal through Akt, MAPK, and many other pathways to regulate cell proliferation, motility, migration, cell differentiation, and apoptosis. Given that ErbB receptors can be over-expressed, amplified, or mutated in various types of cancer, researchers are interested in them as therapeutic targets.
