The antibody detects endogenous level of eIF4B only when phosphorylated at Serine 422.
纯化方法
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography usingepitope-specific phosphopeptide. The antibody against non-phosphopeptide was removedby chromatography using non-phosphopeptide corresponding to the phosphorylation site.
免疫原
Peptide sequence around phosphorylation site of pSer422 (T-G-S (p) -E-S) derived from Human eIF4B. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.
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.
