GDNF stimulation of neuronal cells induces the assembly of a large protein complex containing RET, GRB2 and tyrosine-phosphorylated SHC1, p85 subunit of (PI3K), GAB2 (GAB1 in Hayashi et al. 2000), and Tyrosine-protein phosphatase non-receptor type 11 (PTPN11, SHP-2) (Besset et al. 2000). GAB1 was found in complexes with GRB2 only after GDNF treatment (Hayashi et al. 2000). This contrasts with reports in other systems where GAB2-GRB2 were reported to constitutively associate (Gu et al. 1998). The likely order of recruitment to RET is SHC1, GRB2, GAB1/2, similar to the signaling mechanism of the Interleukin-3 receptor (Gu et al. 2000) and many others (Adams et al. 2012).
