Tick-Borne Encephalitis Virus (TBEV) non-structural protein 4A (NS4A) is a small hydrophobic protein that plays a critical role in the virus's lifecycle. NS4A is involved in the rearrangement of cellular membranes, facilitating the formation of replication organelles necessary for viral RNA synthesis. It acts as a cofactor for the NS3 helicase, enhancing its ATPase activity, which is essential for unwinding viral RNA during replication. NS4A also contributes to the assembly of the viral replication complex, providing a scaffold that induces membrane curvature. Additionally, NS4A has been implicated in inhibiting interferon signaling, thereby modulating the host immune response to favor viral persistence. Research on NS4A focuses on its structural and functional dynamics to understand how it supports viral replication and immune evasion, offering potential targets for antiviral therapeutics. Inhibiting NS4A's interactions and functions may provide a strategy for controlling TBEV infection and reducing the severity of the disease.
