Antigenic domain 1 is required for oligomerization of human cytomegalovirus glycoprotein B.
Human cytomegalovirus (HCMV) glycoprotein B (gB) is an abundant virion envelope protein that has been shown to be essential for the infectivity of HCMV. HCMV gB is also one of the most immunogenic virus-encoded proteins, and a significant fraction of virus neutralizing antibodies are directed at gB. A linear domain of gB designated AD-1 (antigenic domain 1) represents a dominant antibody bindin...
متن کاملIntramolecular disulphide bond arrangements in nonhomologous proteins.
The presence and location of intramolecular disulphide bonds are a key determinant of the structure and function of proteins. Intramolecular disulphide bonds in proteins have previously been analyzed under the assumption that there is no clear relationship between disulphide arrangement and disulphide concentration. To investigate this, a set of sequence nonhomologous protein chains containing ...
متن کاملThe amino terminus of human cytomegalovirus glycoprotein B contains epitopes that vary among strains.
We mapped three antigenic domains of continuous epitopes on human cytomegalovirus (CMV) glycoprotein B (gB) by reacting a panel of independently derived monoclonal antibodies with deletion mutants expressed transiently in COS-1 cells. One of these antigenic domains, DC2, maps in the last 75 amino acids of the carboxy terminus. These epitopes are conserved in strains Towne and AD169, as well as ...
متن کاملA divalent antibody format is required for neutralization of human cytomegalovirus via antigenic domain 2 on glycoprotein B.
Glycoprotein B (gB) of human cytomegalovirus (HCMV) is the dominating protein in the envelope of this virus and gives rise to virus-neutralizing antibodies in most infected individuals. We have previously isolated a neutralizing human antibody specific for antigenic domain 2 (AD-2) on gB, a poorly immunogenic epitope, which nevertheless is capable of eliciting potent neutralizing antibodies. In...
متن کاملB Cell Repertoire Analysis Identifies New Antigenic Domains on Glycoprotein B of Human Cytomegalovirus which Are Target of Neutralizing Antibodies
Human cytomegalovirus (HCMV), a herpesvirus, is a ubiquitously distributed pathogen that causes severe disease in immunosuppressed patients and infected newborns. Efforts are underway to prepare effective subunit vaccines and therapies including antiviral antibodies. However, current vaccine efforts are hampered by the lack of information on protective immune responses against HCMV. Characteriz...
