Background: Argonaute (AGO) is a large family of proteins and a primary component of the RNA-induced silencing complex (RISC). AGO proteins play important roles in regulatory processes, including RNA interference (RNAi) and gene silencing involving many small RNAs. RISC recognizes RNA by base complementary pairing and cleaves or suppresses translation to silence related genes. AGO proteins contain two domains: P-element induced wimpy testis (PIWI) and PIWI-Argonaute-Zwille, which can interact with small interfering RNA or target mRNA and play a key role in RNAi. The AGO protein family is also involved in biological defense mechanisms and may even become a new genome editing tool.
Methods and Results: This review collates and summarizes relevant literature in AGO protein research and describes the biological structure, functions, and characteristics of AGO proteins.
Conclusions: This review paper will provide a reference for related research and applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
