Specification
Product Description
Rabbit recombinant monoclonal antibody raised against human EIF4E.
Antibody Species
Rabbit
Immunogen
Original antibody is raised against a synthetic phosphopeptide corresponding to residues surrounding Ser209 of human EIF4E.
Reactivity
Human
Specificity
This antibody reacts to human EIF4E only when phosphorylated at Ser209. There is no cross-reactivity to EIF4E that is not phosphorylated. This antibody may also react to mouse or rat Phospho-EIF4E (Ser209) as predicted by immunogen homology.

HyperlinkGene Summary
All eukaryotic cellular mRNAs are blocked at their 5-prime ends with the 7-methylguanosine cap structure, m7GpppX (where X is any nucleotide). This structure is involved in several cellular processes including enhanced translational efficiency, splicing, mRNA stability, and RNA nuclear export. EIF4E is a eukaryotic translation initiation factor involved in directing ribosomes to the cap structure of mRNAs. It is a 24-kD polypeptide that exists as both a free form and as part of a multiprotein complex termed EIF4F. The EIF4E polypeptide is the rate-limiting component of the eukaryotic translation apparatus and is involved in the mRNA-ribosome binding step of eukaryotic protein synthesis. The other subunits of EIF4F are a 50-kD polypeptide, termed EIF4A (see MIM 601102), that possesses ATPase and RNA helicase activities, and a 220-kD polypeptide, EIF4G (MIM 600495) (Rychlik et al., 1987 [PubMed 3469651]).[supplied by OMIM
