HCV Core protein Antibody

Packages viral RNA to form a viral nucleocapsid, and promotes virion budding (Probable). Participates in the viral particle production as a result of its interaction with the non-structural protein 5A (PubMed:18524832). Binds RNA and may function as a RNA chaperone to induce the RNA structural rearrangements taking place during virus replication (By similarity). Modulates viral translation initiation by interacting with viral IRES and 40S ribosomal subunit (By similarity). Affects various cell signaling pathways, host immunity and lipid metabolism (Probable). Prevents the establishment of cellular antiviral state by blocking the interferon-alpha/beta (IFN-alpha/beta) and IFN-gamma signaling pathways and by blocking the formation of phosphorylated STAT1 and promoting ubiquitin-mediated proteasome-dependent degradation of STAT1 (By similarity). Activates STAT3 leading to cellular transformation (By similarity). Regulates the activity of cellular genes, including c-myc and c-fos (By similarity). May repress the promoter of p53, and sequester CREB3 and SP110 isoform 3/Sp110b in the cytoplasm (By similarity). Represses cell cycle negative regulating factor CDKN1A, thereby interrupting an important check point of normal cell cycle regulation (By similarity).
