Phospho-Ser358 Eukaryotic Elongation Factor 1 alpha 2 (eEF1A2) Antibody
Affinity purified rabbit polyclonal antibody
- CITATIONS: 1
|Predicted||Chicken, Human, Monkey, Rat, Xenopus|
|Calculated MW||50 KDa|
|Other Names||Elongation factor 1-alpha 2, EF-1-alpha-2, Eukaryotic elongation factor 1 A-2, eEF1A-2, Statin-S1, EEF1A2, EEF1AL, STN|
|Target/Specificity||Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser358 conjugated to KLH.|
|Format||Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.|
|Antibody Specificity||Specific for the ~50k eEF1A2 phosphorylated at Ser358. Immunolabeling of the eEF1A2 band is blocked by the treatment of the lysate with lambda phosphatase (30 minutes, 800 units / 1 mg protein).|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Phospho-Ser358 Eukaryotic Elongation Factor 1 alpha 2 (eEF1A2) Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|

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).
