ERBB receptors are activated via homodimerization or heterodimerization. The ERBB family is unique among various receptor tyrosine kinases; ERBB3 has impaired kinase activity, whereas ERBB2 has no direct ligand. Therefore, heterodimerization is an important mechanism that allows all ERBB receptors to be activated by ligand stimulation.ErbB receptors are overexpressed or mutated in many cancers, especially in breast cancer, ovarian cancer, and non-small cell lung cancer. The overexpression and overactivation …WebJul 3, 2000 · ErbB heterodimerization is a means not only for signal amplification but also for signal diversification.
