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

Specificity:

p-eIF4B (S422) polyclonal antibody detects endogenous levels of eIF4B protein only when phosphorylated at Ser422

Alternative names:

Eukaryotic translation initiation factor 4B; eIF-4B; EIF4B

Species reactivity:

Human,Mouse,Rat

Host:

Rabbit

Ig type:

Rabbit IgG, 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2

Immunogen:

Synthetic phosphopeptide derived from human eIF4B around the phosphorylation site of Serine 422.
