    basic FUNCTION
  • promoting the exchange of RAS-bound GDP by GTP
  • SOS2 is dispensable for NMDA-induced Erk activation and long-term potentiation (LTP) induction
  • SOS1 and SOS2 are ubiquitously expressed, universal Ras guanine nucleotide exchange factors (Ras-GEFs) acting in multiple signal transduction pathways activated by upstream cellular kinases
  • functional redundancy between SOS1 and SOS2 for homeostasis and survival of the full organism and for development and maturation of T and B lymphocytes
  • SOS1 and SOS2 are ubiquitously expressed Ras-guanine exchange factors involved in Erk-MAP kinase pathway activation
  • essential role of SSOS1, SOS2 proteins in cellular proliferation and migration
