Gene Information

human ... AGO2(27161)

General description

Ago2 (argonaute-2), also known as eukaryotic translation initiation factor 2C (EIF2C2), is an essential component for siRNA-directed RNA interference (RNAi) response. Ago2 is an endonuclease required for the unwinding of siRNA duplex and assembly of siRNA into RNA-induced silencing complexes (RISC). Ago2 interacts with DICER1 through its Piwi domain. This Piwi domain is thought to provide RNA cleavage activity via a mechanism similar to RNase H. Ago2 activity is necessary for embryonic development as well as RNA-mediated gene silencing (RNAi).

Immunogen

Linear peptide corresponding to human Ago2.

Application

Immunoprecipitation Analysis: A representative lot from an independent laboratory detected Ago2 in HEK239 cell lysate (Rudel, S., et al. (2008) RNA. 14(6):1244-1253.).

Immunocytochemistry Analysis: A represeentative lot from an independent laboratory detected Ago2 in HEK293, HeLa, and RPE-1 cells (Weinmann, L., et al. (2009). Cell. 136(3):496-507.).

The biological impact of microRNAs (miRNAs) is determined by their targets, and robustly identifying direct miRNA targets remains challenging. Existing methods suffer from high false-positive rates and are unable to effectively differentiate direct miRNA targets from downstream regulatory changes. Here

Regulation of RNA stability plays a crucial role in gene expression control. Deadenylation is the initial rate-limiting step for the majority of RNA decay events. Here, we show that RING finger protein 219 (RNF219) interacts with the CCR4-NOT deadenylase complex.

Bkv-miR-B1-5p is a viral micro-RNA (miRNA) specifically produced during BK polyomavirus (BKPyV) replication. Recent studies have suggested using bkv-miR-B1-5p as a biomarker to monitor viral infection and predict complications in kidney transplant patients. To identify the technical limitations of this
