AGO2（argonaute RISC catalytic component 2），癌症关联基因，基因ID：27161，该基因编码Argonaute家族的一个成员，在RNA干扰中起作用。编码的蛋白质是高度碱性的，包含一个PAZ结构域和一个PIWI结构域它可能与dicer1相互作用，在短干扰RNA介导的基因沉默中发挥作用已发现该基因编码不同亚型的多个转录变体。[由RefSeq提供，2009年9月]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. [provided by RefSeq， Sep 2009]。
