SOS1 binds GRB2 at the plasma membrane after EGF receptor activation. SOS1 activates the small G protein Ras. • eIF-2b is a eukaryotic initiation factor necessary to initiate protein translation. eIF-2b regenerates the GTP-bound form of eIF-2 for an additional cycle in protein synthesis initiation, i.e., its binding to the Met-t-RNA.
WebEphexin5 guanine nucleotide exchange activity we compared its Dbl-homology (DH) domain to the DH domain of other RhoA-specific GEFs (Snyder et al., 2002). We identified within the a5 helix of E5’s DH domain three amino acids that are conserved in other GEFs that, like E5, activate RhoA but not Rac1 and Cdc42 (Figure S2B). To generate a form ...
