Abstract:
A member of the tripartite-motif (TRIM) protein family of E3 ligases, TRIM56 has increasingly been recognized as a versatile player in innate antiviral immunity that operates via catalytically-dependent and catalytically-independent mechanisms. Herein, we provide a concise overview of the various roles that TRIM56 has been demonstrated to play in host interactions with viruses, including its "direct" virus-restricting activities and "indirect" antiviral effects resulting from its positive regulation of innate immune signaling. In addition, we discuss the current understanding of the molecular determinants and underlying biology by which TRIM56 functions in these processes.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
