Product Description

The Translation Initiation Complex Antibody Sampler Kit contains reagents to investigate the initiation of translation within the cell. The kit contains enough primary and secondary antibodies to perform two Western blot experiments per primary antibody.

Specificity / Sensitivity

Each antibody in the Translation Initiation Complex Antibody Sampler Kit detects endogenous levels of its target protein.

Source / Purification

Monoclonal antibodies are produced by immunizing animals with a synthetic petide corresponding to residues surrounding Met316 of human eIF4A protein, Gly188 of human eIF4G, and the sequence of human eIF4E and human eIF4H. Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to a sequence around Gly12 of human eIF4A1, residues at the amino terminus of human eIF4B, Ser422 of human eIF4B, Ser209 of human eIF4E, and Ser1108 of human eIF4GI. Polyclonal antibodies are purified by protein A and peptide affinity chromatography.

Background

A variety of factors contribute to the important biological event of translation initiation. The Eukaryotic initiation Factor 4E (eIF4E) complex of translation initiation factors binds to the 5' m7 GTP cap to open up the mRNA secondary structure and allow small ribosome subunit binding (1). eIF4A, an eIF4 complex component that acts as an ATP-dependent RNA helicase, unwinds the secondary structure of the 5' mRNA untranslated region to mediate ribosome binding (2,3). EIF4E binds to the mRNA cap structure to mediate the initiation of translation (4,5). eIF4E interacts with eIF4G, a scaffold protein that promotes assembly of eIF4E and eIF4A into the eIF4F complex (5). eIF4B is thought to assist the eIF4F complex in translation initiation. eIF4H induces the RNA-dependent ATP hydrolysis catalyzed by the initiation factors eIF4A and eIF4B (2,6). eIF4H was further shown to determine the initial rate and extent of eIF4A-mediated mRNA secondary structure unwinding (7).
