**Background of MX1 Recombinant Protein**
MX1 (Myxovirus resistance protein 1), also known as MxA, is a dynamin-like GTPase encoded by the *MX1* gene in humans. It is a key component of the innate immune system, primarily induced by type I and type III interferons (IFNs) in response to viral infections. MX1 exhibits broad-spectrum antiviral activity, particularly against RNA viruses such as influenza, measles, and SARS-CoV-2. by targeting viral nucleocapsids or replication machinery. Its mechanism involves GTP hydrolysis-driven conformational changes that enable it to oligomerize and disrupt viral processes, either by trapping viral components in the cytoplasm or degrading them.
The recombinant MX1 protein is produced using biotechnological platforms (e.g., bacterial, mammalian, or insect cell systems) to express the purified protein *in vitro*. This engineered form retains the functional domains of native MX1. including the N-terminal GTPase domain and the C-terminal effector region, crucial for its antiviral function. Recombinant MX1 serves as a vital tool for studying host-pathogen interactions, antiviral mechanisms, and interferon signaling pathways. It is also explored for therapeutic applications, such as developing broad antiviral agents or enhancing immune responses in immunocompromised individuals.
Research challenges include optimizing recombinant MX1 stability and activity, as its large size (∼70 kDa) and complex structure pose production difficulties. Nonetheless, advancements in protein engineering and expression systems continue to drive its potential in virology and immunology.
