EIF4B (phospho-Ser422) polyclonal antibody

• Background:

  Required for the binding of mRNA to ribosomes. Functions in close association with EIF4-F and EIF4-A. Binds near the 5'-terminal cap of mRNA in presence of EIF-4F and ATP. Promotes the ATPase activity and the ATP-dependent RNA unwinding activity of both EIF4-A and EIF4-F.It is phosphorylated at Ser-422 by RPS6KA1 and RPS6KB1.phosphorylation enhances the affinity of EIF4B for the EIF3 complex
