Protein Argonaute-1 (AGO1) Antibody

Background

AGO1 is a member of the Argonaute protein family, essential for the RNA-induced silencing complex (RISC), a key player in RNA interference (RNAi) and microRNA (miRNA)-mediated gene regulation. AGO1 primarily binds to miRNAs and facilitates the repression of target mRNA translation without significant endonucleolytic cleavage. Structurally, it contains conserved domains, including the PAZ domain, which binds the 3' end of small RNAs, and the PIWI domain, which has weak or no slicer activity in AGO1. AGO1 is expressed ubiquitously, with a role in post-transcriptional regulation in various biological processes, such as cell proliferation, differentiation, and stress responses. Dysregulation of AGO1 has been linked to diseases such as cancer and autoimmune disorders, where abnormal miRNA-mediated silencing affects critical pathways.
