The overexpression or aberrant activation of Grb2 is closely related to tumorigenesis. The broad involvement of Grb2 in multisteps of the tumorigenesis makes it an excellent target for antitumor therapy, and plenty of studies have shown that Grb2 molecules can be successfully targeted for anti- 生 metastatic therapeutics. Therefore, many Grb2 antagonists have been developed and they show strong antitumor activities. In this article, we summarized the research progress on physiological function of Grb2 and its inhibitors. Keywords growth factor receptor bound protein 2 (Grb2); RTK; tumour therapy; selecti
