Structural and immunological characterization of human cytomegalovirus gp55-116 (gB) expressed in insect cells.
The gene encoding the major envelope glycoprotein complex, gp55-116 (gB), of human cytomegalovirus (HCMV) was expressed at high levels in insect cells utilizing a recombinant baculovirus. The mature intracellular form of the insect-derived gp55-116 was a protein of Mr 150K which contained approximately 50K of N-linked oligosaccharides. The oligosaccharide linkages were almost exclusively endogl...
متن کاملProcessing of human cytomegalovirus envelope glycoproteins in and egress of cytomegalovirus from human astrocytoma cells.
The synthesis of human cytomegalovirus (HCMV) envelope glycoproteins and the production of infectious HCMV in human astrocytoma and skin fibroblast (SF) cells were analysed. HCMV envelope glycoproteins synthesized in astrocytoma cells had lower Mrs than the same glycoproteins synthesized in SF cells regardless of the strain of HCMV used, showing that the differences observed were due to differe...
متن کاملCharacterization 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 کاملThe Human Cytomegalovirus UL116 Gene Encodes an Envelope Glycoprotein Forming a Complex with gH Independently from gL.
UNLABELLED Human cytomegalovirus (HCMV) is a major cause of morbidity and mortality in transplant patients and is the leading viral cause of birth defects after congenital infection. HCMV infection relies on the recognition of cell-specific receptors by one of the viral envelope glycoprotein complexes. Either the gH/gL/gO or the gH/gL/UL128/UL130/UL131A (Pentamer) complex has been found to fulf...
متن کاملThe human cytomegalovirus-specific UL1 gene encodes a late-phase glycoprotein incorporated in the virion envelope.
We have investigated the previously uncharacterized human cytomegalovirus (HCMV) UL1 open reading frame (ORF), a member of the rapidly evolving HCMV RL11 family. UL1 is HCMV specific; the absence of UL1 in chimpanzee cytomegalovirus (CCMV) and sequence analysis studies suggest that UL1 may have originated by the duplication of an ancestor gene from the RL11-TRL cluster (TRL11, TRL12, and TRL13)...
