Product Specific Information

This antibody was cross-absorbed to unphospho-Ago2 (Tyr-393), before affinity purification using phospho-Ago2 (Tyr-393) peptide. The antibody detects a 97 kDa* protein corresponding to the apparent molecular mass of phosphorylated Ago2 on SDS-PAGE immunoblots of human A431 cells that were treated with EGF. This reactivity is not observed after lambda phosphatase dephosphorylation.

Target Information

Ago proteins are broadly expressed in somatic cells, associate with miRNAs and are key actors in different RNA silencing pathways. However, only the Ago2 protein displays endonucleolytic or ″Slicer″ activity and can therefore execute miRNA-directed cleavage of target mRNA, provided that the base-pairing between the Ago2-associated miRNA and the mRNA sequence is perfect. In case of partial complementarity, the Ago2 protein fails to cleave, but instead interferes with translation of the target mRNA via its translational repression activity. Ago2 has been shown to play a non-redundant role in small RNA guided gene silencing processes, including RNA interference, translation repression and heterochromatinization. As a core element of the RISC complex, AGO2 initiates the degradation of target mRNAs through its catalytic activity in gene silencing processes guided by siRNAs or miRNAs. In addition to mRNA degradation or gene silencing guided by miRNAs, Ago2 also acts as a RNA slicer in a Dicer-independent way, as well as a regulator of miRNA maturation. Over-expression of Ago2 has been correlated with several aspects of cancers, including tumor cell growth and the overall survival of cancer patients. Furthermore, gene disruption in the mouse demonstrated that the Ago2 protein is essential for embryonic development and a key regulator of B-lymphoid and erythroid development.
