AGO4 (Q9HCK5) - Overview - Molecular Target Synopsis


AGO4, Protein argonaute-4
UniProt Q9HCK5

Also Known as AGO4_HUMAN, AGO4, EIF2C4, KIAA1567

Required for RNA-mediated gene silencing (RNAi). Binds to short RNAs such as microRNAs (miRNAs) and represses the translation of mRNAs which are complementary to them. Lacks endonuclease activity and does not appear to cleave target mRNAs. Also required for RNA-directed transcription and replication of the human hapatitis delta virus (HDV). Interacts with EIF4B, IMP8, PRMT5, TNRC6A and TNRC6B (PubMed:19167051). Interacts with ZFP36 (PubMed:15766526).
