Antigen/Purification: ExpandCollapse

The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser358 of human eEF1A2.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.

Biological Significance: ExpandCollapse

Eukaryotic Elongation Factor eEF1A exists in two variant forms, eEF1A1 and eEF1A2. While eEF1A1 is almost ubiquitously expressed in humans, eEF1A2 is predominantly found in heart, brain, and skeletal muscle (Knudsen et al., 1993). Expression of eEF1A2 may have a role in ovarian cancer, as its expression is drastically increased in human ovarian tumors (Anand et al., 2002). Due to differences in structural models between the two isoforms, eEF1A1 and eEF1A2 likely have variant-specific phosphorylation sites (Soares et al., 2009). Ribosome-associated JNK phosphorylates Ser358 on eEF1A2 to promote degradation of newly synthesized polypeptides by the proteasome (Gandin et al., 2013).


100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10- mini Western Blots.

For long term storage –20° C is recommended. Stable at –20° C for at least 1 year.

eEF1A2 Ser358 Antibody
Western blot of mouse hippocampal lysate showing specific immunolabeling of the ~50 kDa eEF1A2 protein phosphorylated at Ser358 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (λ-Ptase, 800 units/1mg protein for 30 min).
