The eukaryotic translation initiation factor 4 gamma 1 encoded by EIF4G1 is a component of the multi-subunit protein complex EIF4F. This complex facilitates the recruitment of mRNA to the ribosome, which is a rate-limiting step during the initiation phase of protein synthesis. The recognition of the mRNA cap and the ATP-dependent unwinding of 5'-terminal secondary structure is catalyzed by factors in this complex. The subunit encoded by this gene is a large scaffolding protein that contains binding sites for other members of the EIF4F complex. A domain at its N-terminus can also interact with the poly(A)-binding protein, which may mediate the circularization of mRNA during translation. Alternative splicing results in multiple transcript variants, some of which are derived from alternative promoter usage.

Phospho-eIF4G (S1148) Polyclonal Antibody detects endogenous levels of eIF4G protein only when phosphorylated at S1148.

Optimal working dilutions should be determined experimentally by the investigator. Suggested starting dilutions are as follows: IHC-p: 1:100-1:300, ELISA: 1:40000. Not yet tested in other applications.
