Argonaute 2 (AGO2) Antibody – Rabbit Polyclonal

This gene encodes a member of the Argonaute family of proteins which play a role in RNA interference. The encoded protein is highly basic, and contains a PAZ domain and a PIWI domain. It may interact with dicer1 and play a role in short-interfering-RNA-mediated gene silencing. Multiple transcript variants encoding different isoforms have been found for this gene.

AGO2: the endonuclease in RNA-induced silencing complexes (RISC) that cleaves siRNA/mRNA heteroduplexes bound to RISC. Ago2, along with Dicer and TRBP, are major components of RISC. Interacts with Dicer1 through its Piwi domain. Required for proper fibroblast growth factor signaling during gastrulation. Essential for embryonic development as well as RNA-mediated gene silencing (RNAi).
