背景信息

**Background of AGO1 Recombinant Protein**

Argonaute 1 (AGO1) is a member of the evolutionarily conserved Argonaute protein family, central to RNA-induced silencing complex (RISC)-mediated gene regulation. These proteins play critical roles in RNA interference (RNAi) pathways by binding small non-coding RNAs, such as microRNAs (miRNAs) or small interfering RNAs (siRNAs), to guide post-transcriptional gene silencing. AGO1. predominantly expressed in mammals, facilitates target mRNA degradation or translational repression through sequence-specific interactions, thereby regulating diverse biological processes, including development, antiviral defense, and cellular homeostasis.

Structurally, AGO1 contains two primary domains: the PAZ domain, which anchors the 3′-end of small RNAs, and the PIWI domain, which adopts an RNase H-like fold responsible for endonucleolytic cleavage (slicing) of complementary mRNAs. Its function is tightly regulated by post-translational modifications and interactions with co-factors like Dicer and GW182.

Recombinant AGO1 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its molecular mechanisms, structural dynamics, and role in disease. Engineered versions often include affinity tags (e.g., His-tag) for purification and tracking. Researchers utilize recombinant AGO1 to dissect RISC assembly, miRNA-mRNA interactions, and off-target effects in gene silencing. It also serves as a tool for developing RNA-based therapeutics, such as siRNA delivery systems for cancers or viral infections.

Despite challenges in maintaining its native conformation and enzymatic activity *in vitro*, recombinant AGO1 remains indispensable for advancing RNA biology and precision medicine. Its study continues to uncover novel insights into gene regulation networks and therapeutic strategies targeting dysregulated pathways in diseases.
