CC -!- FUNCTION: [Mature core protein]: Packages viral RNA to form a viral
CC nucleocapsid, and promotes virion budding (Probable). Participates in
CC the viral particle production as a result of its interaction with the
CC non-structural protein 5A (By similarity). Binds RNA and may function
CC as a RNA chaperone to induce the RNA structural rearrangements taking
CC place during virus replication (By similarity). Modulates viral
CC translation initiation by interacting with viral IRES and 40S ribosomal
CC subunit (By similarity). Affects various cell signaling pathways, host
CC immunity and lipid metabolism (Probable). Prevents the establishment of
CC cellular antiviral state by blocking the interferon-alpha/beta (IFN-
CC alpha/beta) and IFN-gamma signaling pathways and by blocking the
CC formation of phosphorylated STAT1 and promoting ubiquitin-mediated
CC proteasome-dependent degradation of STAT1 (By similarity). Activates
CC STAT3 leading to cellular transformation (By similarity). Regulates the
CC activity of cellular genes, including c-myc and c-fos (By similarity).
CC May repress the promoter of p53, and sequester CREB3 and SP110 isoform
CC 3/Sp110b in the cytoplasm (By similarity). Represses cell cycle
CC negative regulating factor CDKN1A, thereby interrupting an important
CC check point of normal cell cycle regulation (By similarity). Targets
CC transcription factors involved in the regulation of inflammatory
CC responses and in the immune response: suppresses TNF-induced NF-kappa-B
CC activation, and activates AP-1 (By similarity). Binds to dendritic
CC cells (DCs) via C1QR1, resulting in down-regulation of T-lymphocytes
CC proliferation (By similarity). Alters lipid metabolism by interacting
CC with hepatocellular proteins involved in lipid accumulation and storage
CC (By similarity). Induces up-regulation of FAS promoter activity, and
CC thereby contributes to the increased triglyceride accumulation in
CC hepatocytes (steatosis) (By similarity). {ECO:0000250|UniProtKB:P26662,

CC -!- FUNCTION: [Envelope glycoprotein E1]: Forms a heterodimer with envelope
CC glycoprotein E2, which mediates virus attachment to the host cell,
CC virion internalization through clathrin-dependent endocytosis and
CC fusion with host membrane (By similarity). Fusion with the host cell is
CC most likely mediated by both E1 and E2, through conformational
CC rearrangements of the heterodimer required for fusion rather than a
CC classical class II fusion mechanism (By similarity). E1/E2 heterodimer
CC binds host apolipoproteins such as APOB and ApoE thereby forming a
CC lipo-viro-particle (LVP) (By similarity). APOE associated to the LVP
CC allows the initial virus attachment to cell surface receptors such as
CC the heparan sulfate proteoglycans (HSPGs), syndecan-1 (SDC1), syndecan-
CC 1 (SDC2), the low-density lipoprotein receptor (LDLR) and scavenger
CC receptor class B type I (SCARB1) (By similarity). The cholesterol
CC transfer activity of SCARB1 allows E2 exposure and binding of E2 to
CC SCARB1 and the tetraspanin CD81 (By similarity). E1/E2 heterodimer
CC binding on CD81 activates the epithelial growth factor receptor (EGFR)
CC signaling pathway (By similarity). Diffusion of the complex E1-E2-EGFR-
CC SCARB1-CD81 to the cell lateral membrane allows further interaction
CC with Claudin 1 (CLDN1) and occludin (OCLN) to finally trigger HCV entry
CC (By similarity). {ECO:0000250|UniProtKB:P27958}.
CC -!- FUNCTION: [Envelope glycoprotein E2]: Forms a heterodimer with envelope
CC glycoprotein E1, which mediates virus attachment to the host cell,
CC virion internalization through clathrin-dependent endocytosis and
CC fusion with host membrane (By similarity). Fusion with the host cell is
CC most likely mediated by both E1 and E2, through conformational
CC rearrangements of the heterodimer required for fusion rather than a
CC classical class II fusion mechanism (By similarity). The interaction
CC between envelope glycoprotein E2 and host apolipoprotein E/APOE allows
CC the proper assembly, maturation and infectivity of the viral particles
CC (By similarity). This interaction is probably promoted via the up-
CC regulation of cellular autophagy by the virus (By similarity). E1/E2
CC heterodimer binds host apolipoproteins such as APOB and APOE thereby
CC forming a lipo-viro-particle (LVP) (By similarity). APOE associated to
CC the LVP allows the initial virus attachment to cell surface receptors
CC such as the heparan sulfate proteoglycans (HSPGs), syndecan-1 (SDC1),
CC syndecan-1 (SDC2), the low-density lipoprotein receptor (LDLR) and
CC scavenger receptor class B type I (SCARB1) (By similarity). The
CC cholesterol transfer activity of SCARB1 allows E2 exposure and binding
CC of E2 to SCARB1 and the tetraspanin CD81 (By similarity). E1/E2
CC heterodimer binding on CD81 activates the epithelial growth factor
CC receptor (EGFR) signaling pathway (By similarity). Diffusion of the
CC complex E1-E2-EGFR-SCARB1-CD81 to the cell lateral membrane allows
CC further interaction with Claudin 1 (CLDN1) and occludin (OCLN) to
CC finally trigger HCV entry (By similarity). Inhibits host EIF2AK2/PKR
CC activation, preventing the establishment of an antiviral state (By
CC similarity). Viral ligand for CD209/DC-SIGN and CLEC4M/DC-SIGNR, which
CC are respectively found on dendritic cells (DCs), and on liver
CC sinusoidal endothelial cells and macrophage-like cells of lymph node
CC sinuses (By similarity). These interactions allow the capture of
CC circulating HCV particles by these cells and subsequent facilitated
CC transmission to permissive cells such as hepatocytes and lymphocyte
CC subpopulations (By similarity). The interaction between E2 and host
CC amino acid transporter complex formed by SLC3A2 and SLC7A5/LAT1 may
CC facilitate viral entry into host cell (By similarity).
CC {ECO:0000250|UniProtKB:P26664, ECO:0000250|UniProtKB:P27958}.
CC -!- FUNCTION: [Viroporin p7]: Ion channel protein that acts as a viroporin
CC and plays an essential role in the assembly, envelopment and secretion
CC of viral particles (By similarity). Regulates the host cell secretory
CC pathway, which induces the intracellular retention of viral
CC glycoproteins and favors assembly of viral particles (By similarity).
CC Creates a pore in acidic organelles and releases Ca(2+) and H(+) in the
CC cytoplasm of infected cells, leading to a productive viral infection
CC (By similarity). High levels of cytoplasmic Ca(2+) may trigger membrane
CC trafficking and transport of viral ER-associated proteins to
CC viroplasms, sites of viral genome replication (Probable). This ionic
CC imbalance induces the assembly of the inflammasome complex, which
CC triggers the maturation of pro-IL-1beta into IL-1beta through the
CC action of caspase-1 (By similarity). Targets also host mitochondria and
CC induces mitochondrial depolarization (By similarity). In addition of
CC its role as a viroporin, acts as a lipid raft adhesion factor (By
CC similarity). {ECO:0000250|UniProtKB:P27958,
CC ECO:0000250|UniProtKB:Q99IB8, ECO:0000305}.
CC -!- FUNCTION: [Protease NS2]: Cysteine protease required for the
CC proteolytic auto-cleavage between the non-structural proteins NS2 and

CC initiation of viral particle assembly by mediating the interaction
CC between structural and non-structural proteins (By similarity).
CC {ECO:0000250|UniProtKB:P26663, ECO:0000250|UniProtKB:P27958}.
CC -!- FUNCTION: [Serine protease/helicase NS3]: Displays three enzymatic
CC activities: serine protease with a chymotrypsin-like fold, NTPase and
CC RNA helicase (By similarity). NS3 serine protease, in association with
CC NS4A, is responsible for the cleavages of NS3-NS4A, NS4A-NS4B, NS4B-
CC NS5A and NS5A-NS5B (By similarity). The NS3/NS4A complex prevents
CC phosphorylation of host IRF3, thus preventing the establishment of
CC dsRNA induced antiviral state (By similarity). The NS3/NS4A complex
CC induces host amino acid transporter component SLC3A2, thus contributing
CC to HCV propagation (By similarity). NS3 RNA helicase binds to RNA and
CC unwinds both dsDNA and dsRNA in the 3' to 5' direction, and likely
CC resolves RNA complicated stable secondary structures in the template
CC strand (By similarity). Binds a single ATP and catalyzes the unzipping
CC of a single base pair of dsRNA (By similarity). Inhibits host antiviral
CC proteins TBK1 and IRF3 thereby preventing the establishment of an
CC antiviral state (By similarity). Cleaves host MAVS/CARDIF thereby
CC preventing the establishment of an antiviral state (By similarity).

CC -!- FUNCTION: [Non-structural protein 4B]: Induces a specific membrane
CC alteration that serves as a scaffold for the virus replication complex
CC (By similarity). This membrane alteration gives rise to the so-called
CC ER-derived membranous web that contains the replication complex (By
CC similarity). NS4B self-interaction contributes to its function in
CC membranous web formation (By similarity). Promotes host TRIF protein
CC degradation in a CASP8-dependent manner thereby inhibiting host TLR3-
CC mediated interferon signaling (By similarity). Disrupts the interaction
CC between STING and TBK1 contributing to the inhibition of interferon
CC signaling (By similarity). {ECO:0000250|UniProtKB:P27958}.
CC -!- FUNCTION: [Non-structural protein 5A]: Phosphorylated protein that is
CC indispensable for viral replication and assembly (By similarity). Both
CC hypo- and hyperphosphorylated states are required for the viral life
CC cycle (By similarity). The hyperphosphorylated form of NS5A is an
CC inhibitor of viral replication (By similarity). Involved in RNA-binding
CC and especially in binding to the viral genome (By similarity). Zinc is
CC essential for RNA-binding (By similarity). Participates in the viral
CC particle production as a result of its interaction with the mature
CC viral core protein (By similarity). Its interaction with host VAPB may
CC target the viral replication complex to vesicles (By similarity). Down-
CC regulates viral IRES translation initiation (By similarity). Mediates
CC interferon resistance, presumably by interacting with and inhibiting
CC host EIF2AK2/PKR (By similarity). Prevents BIN1-induced apoptosis (By

CC nucleocapsid buds at the ER membrane where E1/E2 glycoproteins are
CC anchored and afterward associate with nascent lipid droplet to acquire
CC APOE and APOC. Secretion of viral particles is probably regulated by
CC viroporin p7. {ECO:0000305}.
