Conformational Flexibility in the Immunoglobulin-Like Domain of the Hepatitis C Virus Glycoprotein E2
The hepatitis C virus (HCV) glycoprotein E2 is the major target of neutralizing antibodies and is therefore highly relevant for vaccine design. Its structure features a central immunoglobulin (Ig)-like β-sandwich that contributes to the binding site for the cellular receptor CD81. We show that a synthetic peptide corresponding to a β-strand of this Ig-like domain forms an α-helix in complex wit...
متن کاملIdentification of Aptamer-Binding Sites in Hepatitis C Virus Envelope Glycoprotein E2
Hepatitis C Virus (HCV) encodes two envelope glycoproteins, E1 and E2. Our previous work selected a specific aptamer ZE2, which could bind to E2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting HCV. In this study, the binding sites between E2 and aptamer ZE2 were further explored. E2 was truncated to 15...
متن کاملAnalysis of a highly flexible conformational immunogenic domain a in hepatitis C virus E2.
Hepatitis C (HCV) E2 glycoprotein is involved in virus attachment and entry, and its structural organization is largely unknown. Characterization of a panel of human monoclonal antibodies (HMAbs) to HCV by competition studies has led to an immunogenic organization model of E2 with three domains designated A, B, and C and epitopes in each domain having similar structural and functional propertie...
متن کاملAnalysis of antigenicity and topology of E2 glycoprotein present on recombinant hepatitis C virus-like particles.
Purification of hepatitis C virus (HCV) from sera of infected patients has proven elusive, hampering efforts to perform structure-function analysis of the viral components. Recombinant forms of the viral glycoproteins have been used instead for functional studies, but uncertainty exists as to whether they closely mimic the virion proteins. Here, we used HCV virus-like particles (VLPs) generated...
متن کاملgb virus c/hepatitis g virus envelope glycoprotein e2: computational molecular features and immunoinformatics study
conclusions the comprehensive analysis of a protein with important roles has never been easy, and in case of e2 envelope glycoprotein of hgv, there is no much data on its molecular and immunological features, clinical significance and its pathogenic potential in hepatitis or any other gbv-c related diseases. so, results of the present study may explain some structural, physiological and immunol...
