Characterization of a novel third member of the human cytomegalovirus glycoprotein H-glycoprotein L complex.
A prerequisite for understanding the molecular function of the human cytomegalovirus (HCMV) gH (UL75)-gL (UL115) complex is a detailed knowledge of the structure of this complex in its functional form, as it is present in mature virions. The gH protein is known to be a component of a 240-kDa envelope complex designated as gCIII (D. R. Gretch, B. Kari, L. Rasmussen, R. C. Gehrz, and M. F. Stinsk...
متن کاملHuman herpesvirus 6 variant A glycoprotein H-glycoprotein L-glycoprotein Q complex associates with human CD46.
Human CD46 is a cellular receptor for human herpesvirus 6 (HHV-6). Virus entry into host cells requires a glycoprotein H (gH)-glycoprotein L (gL) complex. We show that the CD46 ectodomain blocked HHV-6 infection and bound a complex of gH-gL and the 80-kDa U100 gene product, designated glycoprotein Q, indicating that the complex is a viral ligand for CD46.
متن کاملDifferential effects of glycoprotein B epitope-specific antibodies on human cytomegalovirus-induced cell-cell fusion.
Attachment of, and cell-cell fusion induced by, human cytomegalovirus were studied in the presence of neutralizing monospecific antibodies against antigenic domains 1 (AD-1) or 2 (AD-2) of glycoprotein B (gB, gpUL55). Efficient inhibition of the virion-mediated fusion event was consistently observed for the human AD-2-specific antibody as determined by a reporter gene activation assay based on ...
متن کاملStructural domains involved in human cytomegalovirus glycoprotein B-mediated cell-cell fusion.
A novel fusion assay was established to determine fusion activity with cocultivated human foreskin fibroblasts of stable transfectants derived from human astrocytoma cells (U373) expressing authentic or mutagenized human cytomegalovirus glycoprotein B (HCMV gB; gpUL55). Compared to transfectants expressing authentic HCMV gB, those expressing gB forms with a deletion of hydrophobic domain 1 (hd1...
