LSM14A is an RNA-binding protein essential for processing body (P-body) formation, cytoplasmic membraneless organelles that sequester translationally inactive mRNAs 123. LSM14A acts as a translational repressor and directly associates with core P-body proteins like DDX6 to facilitate their condensation through liquid-liquid phase separation 45. Beyond canonical P-body assembly, LSM14A plays critical roles in innate immunity by sensing viral RNA to activate interferon-β production pathways 6, while also regulating translation of DNA damage response genes including RTEL1 and LIG4 upon genotoxic stress 7. In disease contexts, LSM14A is a core component of the YAP/TAZ-driven P-body axis that promotes colorectal cancer cell proliferation and tumorigenesis 8. Genome-wide association studies identified LSM14A variants associated with diabetic kidney disease susceptibility 9. However, LSM14A appears dispensable for spermatogenesis, suggesting functional redundancy among LSM family members in certain contexts 10. Pathogenic viruses exploit LSM14A's antiviral function: SFTSV NSs protein directly inhibits LSM14A-mediated interferon signaling to evade host immunity 11.
