Abstract
Using the yeast two-hybrid system, we have isolated a new substrate of the insulin-like growth factor I receptor (IGF-IR), identified as Grb10, a member of the family of SH2 domain proteins. With the help of several mutants of the IGF-IR, we have mapped the binding site of Grb10 between amino acids 1229 and 1245 of the receptor, a sequence that is dispensable for the mitogenic activity of the IGF-IR. Grb10 coprecipitates with the IGF-IR in cell lysates and is probably involved in the regulation of its activity.Entities:
