GRB2 [ENSP00000339007]
 
growth factor receptor-bound protein 2; Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway
KIT [ENSP00000288135]
 
v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog; This is the receptor for stem cell factor (mast cell growth factor). It has a tyrosine-protein kinase activity. Binding of the ligands leads to the autophosphorylation of KIT and its association with substrates such as phosphatidylinositol 3-kinase (Pi3K)
