SHP2 (PTPN11) interacts with phosphotyrosine-986 of the phosphorylated Leptin receptor (LEPR) (Carpenter et al. 1998). The corresponding site in mouse is phosphotyrosine-985 and in rat phosphotyrosine-986.
SHP2 and SOCS3 compete for the same binding site on LEPR. SHP2 activates MAPK signaling, probably by recruiting GRB2:SOS which activates RAS.
