This study explores the interaction of HCVc174 protein with key candidates through affinity purification, comparative SDS-PAGE, LC-MS/MS analysis, and confirming RNA-dependent interactions. Additionally, it delves into subcellular distributions and HCVc174 cytoplasmic confinement during viral replication.
