該基因編碼Argonaute家族的一個成員，在RNA干擾中起作用。編碼的蛋白質是高度堿性的，包含PAZ結構域和PIWI結構域，可能在短干擾RNA介導的基因沉默中發揮作用該基因位于1號染色體上，由Argonaute 4和真核翻譯起始因子2C，1等家族成員串聯而成。已鑒定出兩個編碼不同亞型的轉錄變體[由RefSeq提供，2008年7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, contains a PAZ domain and a PIWI domain, and may play a role in short-interfering-RNA-mediated gene silencing. This gene is located on chromosome 1 in a tandem cluster of closely related family members including argonaute 4 and eukaryotic translation initiation factor 2C, 1. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]
