Cleavage sites within the poliovirus capsid protein precursors.
Partial amino-terminal sequence analysis was performed on radiolabeled polio-virus capsid proteins VP1, VP2, and VP3. A computer-assisted comparison of the amino acid sequences obtained with that predicted by the nucleotide sequence of the poliovirus genome allows assignment of the amino terminus of each capsid protein to a unique position within the virus polyprotein. Sequence analysis of tryp...
متن کاملEfficient analysis of nonviable poliovirus capsid mutants.
Nonviable poliovirus capsid mutants were studied by an efficient infection-transfection system. Phenotypically, nonviable poliovirus capsid mutants appear to segregate into three classes: those that form only protomers, those that can form pentamers, and one that can form completed virions.
متن کاملThe conserved N-terminus of human rhinovirus capsid protein VP4 contains membrane pore-forming activity and is a target for neutralizing antibodies
Human rhinovirus is the causative agent of the common cold and belongs to the non-enveloped picornavirus family. A trigger such as receptor binding or low pH initiates conformational changes in the capsid that allow the virus to attach to membranes and form a pore for the translocation of viral RNA into the cytoplasm. We previously showed that recombinant capsid protein VP4 was able to form mem...
متن کاملAntigenic relationships among human rotaviruses as determined by outer capsid protein VP4.
cDNA clones representing the VP4 gene of symptomatic human rotavirus strain KU (VP7 serotype 1) or DS-1 (VP7 serotype 2) or asymptomatic human rotavirus strain 1076 (VP7 serotype 2) were constructed and inserted into a baculovirus expression vector under the control of the polyhedrin promoter. The resulting recombinants expressed the appropriate authentic VP4 rotavirus outer capsid protein. Gui...
متن کاملIdentification of T-helper epitopes in the VP1 capsid protein of poliovirus.
Poliovirus-specific T lymphocytes were isolated from virus-immunized mice of different H-2 haplotypes. Immunological characterization of this population indicates that the effector population involved in the observed poliovirus-specific proliferative response was that of CD4-positive T-helper cells. Proliferative responses also were induced within these T-lymphocyte populations upon stimulation...
