The hepatitis C virus (HCV) core protein is a structural component of the HCV virion, encoded by the highly conserved 5' end of the viral genome. As the first protein synthesized during viral replication, it plays a critical role in viral assembly and host interactions. The mature core protein consists of approximately 191 amino acids (∼21 kDa) and contains three conserved domains: a hydrophilic N-terminal domain involved in RNA binding, a C-terminal hydrophobic signal sequence for membrane anchoring, and a central intrinsically disordered region mediating protein-protein interactions.
Recombinant HCV core protein is typically produced using heterologous expression systems (e.g., E. coli, yeast, or mammalian cells) for research and diagnostic applications. Its production has enabled significant advances in understanding HCV biology, particularly its roles in immune evasion, lipid metabolism modulation, and potential oncogenic properties through interactions with host cell pathways. The protein's antigenic properties make it valuable for developing serological assays to detect HCV-specific antibodies in patient samples.
Structural studies using recombinant core protein have revealed its ability to form nucleocapsid-like particles and interact with viral RNA. However, challenges remain in maintaining proper conformation during recombinant production due to the protein's inherent hydrophobicity and tendency to aggregate. Researchers often employ solubility tags (e.g., GST, His-tag) or alternative expression strategies to overcome these limitations.
Current applications extend to vaccine development, as the core protein contains conserved T-cell epitopes that may elicit cross-genotypic immune responses. Its role in diagnostic test development remains crucial, particularly in differentiating acute and chronic infections. Ongoing research continues to explore core protein's interactions with host factors like lipid droplets and its potential as a therapeutic target, despite not being directly inhibited by current direct-acting antivirals.
