Structural highlights
Function
SH2B2_RAT Adapter protein for several members of the tyrosine kinase receptor family. Involved in multiple signaling pathways. Binds to EPOR and suppresses EPO-induced STAT5 activation, possibly through a masking effect on STAT5 docking sites in EPOR. Suppresses PDGF-induced mitogenesis (By similarity). Involved in stimulation of glucose uptake by insulin. Involved in coupling from immunoreceptor to Ras signaling. Acts as a negative regulator of cytokine signaling in collaboration with CBL. Induces cytoskeletal reorganization and neurite outgrowth in cultured neurons.[1] [2] [3] [4]
