LSM14A, a member of the LSM protein family, is crucial in RNA metabolism, including mRNA processing, transport, and stabilization. It features conserved N-terminal LSM domains that facilitate protein interactions and complex assembly. Localized in cytoplasmic foci like P-bodies and stress granules, LSM14A regulates mRNA stability and translation, especially under cellular stress. It also contributes to innate immunity by modulating interferon signaling and antiviral responses, potentially via interactions with viral components. Recombinant human LSM14A is produced using bacterial (e.g., *E. coli*) or mammalian expression systems, followed by purification. This engineered protein enables studies on RNA-protein dynamics, antiviral mechanisms, and RNA homeostasis. It serves as a tool for exploring therapeutic targets in diseases linked to RNA dysregulation, such as viral infections and cancers, advancing drug discovery and host-pathogen research.
