Our Argonaute 2 (Ser-387) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects chicken, human, mouse, rat, and Xenopus Argonaute 2 (Ser-387) and is antigen affinity purified. It is great for use in WB, ICC.

Western blot analysis of mouse recombinant Ago2 full length protein (lanes 1-4). The blot was treated with lambda phosphatase (lanes 2 & 4) then probed with rabbit polyclonal anti-Ago2 (AP5281) (lanes 1 & 2) and rabbit polyclonal anti-Ago2 (Ser-387) phospho-specific antibody (lanes 3 & 4).

Target

Argonaute 2 (Ser-387)

Scientific Background

Several classes of small RNAs, including short interfering RNAs (siRNAs), microRNAs (miRNAs), and Piwi-interacting RNAs (piRNAs) have been identified. MicroRNAs are about 21 nucleotides in length and have been implicated in many cellular processes such as development, differentiation, and stress response. These small RNAs function together with complexes called micro-ribonucleoproteins (miRNPs) to regulate gene expression by modulating mRNA translation or stability. Among the most important components in these complexes are argonaute proteins. There are four members in the mammalian argonaute family and only argonaute 2 (Ago2) possesses the Slicer endonuclease activity. Argonaute proteins participate in various steps of microRNA-mediated gene silencing, such as repression of translation and mRNA turnover. These activities may be regulated by cell signaling events that alter argonaute phosphorylation. EGFR phosphorylates Tyr-393 in Ago2, which reduces binding to Dicer and inhibits miRNA processing. Akt3 phosphorylates Ago2 at Ser-387 leading to reduced mRNA cleavage and enhanced translational repression.

Gene Name

AGO2

Molecular Weight

Immunogen

Phospho-Ago2 (Ser-387) synthetic peptide (coupled to KLH) corresponding to amino acid residues surrounding serine 387 in human Ago2. This peptide sequence is highly conserved in mouse, rat, chick, and fish Ago2. The site is also conserved in Ago1 and Ago4, but the homology surrounding the site is low between Ago2 and these two family members.

Storage

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Physical State

Liquid

Buffer

PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Dilution Ranges

Conjugate

Unconjugated

Specificity

This antibody was cross-absorbed to unphospho-Ago2 (Ser-387), before affinity purification using phospho-Ago2 (Ser-387) peptide (without carrier). The antibody detects a 97 kDa* protein corresponding to the apparent molecular mass of phosphorylated Ago2 on SDS-PAGE immunoblots of human A431 cells treated with Calyculin A and mouse recombinant Ago2 full length protein. This reactivity is not observed after lambda phosphatase dephosphorylation.
