WebApr 6, 2024 · A single SOS can associate with at least two Grb2 molecules, and these multivalent interactions result in an extended two-dimensional network assembly of LAT:Grb2:SOS on the membrane in a phosphorylation-dependent manner ( 58, 59 ). This complex has been shown to play an important role in T cell signaling ( 60, 61). WebThe GRB2 adaptor protein binds sequentially and mutually exclusively to the RTK and Sos. SH3 domains, such as those on GRB2, bind to proline-rich sequences in downstream signaling molecules. Sos activates the Ras/MAPK signaling cascade by acting as a GEF for Ras.
