Reconstitution

Allow the vial and reconstitution buffer to equilibrate to room temperature. Briefly centrifuge or tap down the vial to ensure that all lyophilized powder is collected at the bottom of the vial. For the reconstitution of this product, we recommend adding PBS or sterile water to achieve a final antibody concentration of 1 mg/mL. Allow the vial to reconstitute for 10-15 minutes at room temperature with gentle agitation. Avoid vigorous shaking that can cause foaming and antibody denaturation. Aliquot into volumes based on your experiment and store liquid protein at -20°C or -80°C for long time.

Buffer

Lyophilized from sterile Tris, NaCl

Preservative

None

Storage

Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Argonaute 2, RISC Catalytic Component

Function

Required for RNA-mediated gene silencing (RNAi) by the RNA-induced silencing complex (RISC). The 'minimal RISC' appears to include AGO2 bound to a short guide RNA such as a microRNA (miRNA) or short interfering RNA (siRNA). These guide RNAs direct RISC to complementary mRNAs that are targets for RISC-mediated gene silencing. The precise mechanism of gene silencing depends on the degree of complementarity between the miRNA or siRNA and its target. Binding of RISC to a perfectly complementary mRNA generally results in silencing due to endonucleolytic cleavage of the mRNA specifically by AGO2. Binding of RISC to a partially complementary mRNA results in silencing through inhibition of translation, and this is independent of endonuclease activity. May inhibit translation initiation by binding to the 7-methylguanosine cap, thereby preventing the recruitment of the translation initiation factor eIF4-E. May also inhibit translation initiation via interaction with EIF6, which itself binds to the 60S ribosomal subunit and prevents its association with the 40S ribosomal subunit. The inhibition of translational initiation leads to the accumulation of the affected mRNA in cytoplasmic processing bodies (P-bodies), where mRNA degradation may subsequently occur. In some cases RISC-mediated translational repression is also observed for miRNAs that perfectly match the 3' untranslated region (3'-UTR). Can also up-regulate the translation of specific mRNAs under certain growth conditions. Binds to the AU element of the 3'-UTR of the TNF (TNF-alpha) mRNA and up-regulates translation under conditions of serum starvation. Also required for transcriptional gene silencing (TGS), in which short RNAs known as antigene RNAs or agRNAs direct the transcriptional repression of complementary promoter regions.

Cellular Location

Nucleus; P-body. Translational repression of mRNAs results in their recruitment to P-bodies. Translocation to the nucleus requires IMP8.

PTM

Hydroxylated. 4-hydroxylation appears to enhance protein stability but is not required for miRNA-binding or endonuclease activity.
Ubiquitinated on surface-exposed lysines by a SCF-like E3 ubiquitin-protein ligase complex containing ZSWIM8 during target-directed microRNA degradation (TDMD), a process that mediates degradation of microRNAs (miRNAs). Ubiquitination by the SCF-like E3 ubiquitin-protein ligase complex containing ZSWIM8 leads to its subsequent degradation, thereby exposing miRNAs for degradation. ZSWIM8 recognizes and binds AGO2 when it is engaged with a TDMD target.
