Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: T57

Protein UniProt: P13639

Protein SigNET: P13639

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human EEF2 sequence peptide Cat. No.: PE-04AQY90

Antibody Immunogen Sequence: ETRF(pT)DTR(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues E53 to R60; In the N-terminal portion of the protein. One of the major in vivo phosphorylation sites in EEF2.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: EEF2 catalyzes the GTP-dependent ribosomal translocation step during translation elongation in protein synthesis. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. It catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome.
