Disease relevance of BKPyVgp4

  • It was also shown that the 16S late mRNA from infected baby mouse kidney cells could be translated into a polypeptide which was identical to or similar to virion protein VP1 in every aspect examined, including the patter of peptide mapping by limited proteolysis [1].
  • The crystallographically determined structure of simian virus 40 shows that the 72 pentamers of viral protein VP1, which form the outer shell, have identical conformations except for the C-terminal arms of their subunits [2].
  • Data from earlier immunoblotting experiments demonstrated that rabbits inoculated i.v. with purified infectious BK virus produced antibodies not only to the viral structural protein VP1 but also to migrating polypeptides of a molecular mass ranging from 14-16 kDa [3].
  • Nuclear localization of avian polyomavirus structural protein VP1 is a prerequisite for the formation of virus-like particles [4].
  • We have identified two HLA-A*0201-restricted nine-amino-acid cytotoxic T lymphocyte (CTL) epitopes of the BKV major capsid protein VP1, VP1(p44), and VP1(p108) [5].
 

High impact information on BKPyVgp4

  • Temperature-sensitive (ts) assembly mutants of the tumorigenic virus simian virus 40 (SV40) fail to follow the normal pathway of virion morphogenesis at 40 degrees C. The mutations were previously mapped to the gene coding for the major virion protein VP1 and fall into three groups: tsB, tsBC, and tsC [6].
  • Blot hybridization analysis of poly(A)-selected RNA demonstrated that the level of synthesis of the major late structural protein VP-1 in COS-1 cells was due to increased transcription [7].
  • The functionally bicistronic major late 16S and functionally tricistronic major late 19S mRNA species of SV40 contain the leader-encoded open reading frames (ORFs) LP1, located upstream of the sequence encoding the virion protein VP1, and LP1*, located upstream of the sequence encoding the virion proteins VP2 and VP3 [8].
  • When these two progeny virion types were labeled in vivo with 32P and subjected to isoelectric focusing followed by sodium dodecyl sulfate-polyacrylamide gel electrophroesis in the second dimension, differences in the phosphorylation pattern of the major virus-encoded structural protein VP1 species were observed [9].
  • Because the engineering of these genomes created a defect in the structural protein VP1, their DNA replicating activities could be compared without the complication of secondary infection of adjacent cells and amplification of the replication signal [10].
 

Biological context of BKPyVgp4

 

Anatomical context of BKPyVgp4

  • In the present study, BKV were analyzed to determine if mutations in the non-coding control region (NCCR), and specific BKV sub-types defined by sequence analysis of major capsid protein VP1, were associated with development of hemorrhagic cystitis in hematopoietic stem cell transplant recipients [14].
  • Based on the present results, we propose that autologous dsDNA can be rendered immunogenic through complex formation with viral DNA binding protein(s) such as the structural protein VP1 or the tumour antigen T. Such DNA-protein complexes may bypass a putative T-cell tolerance to autologous dsDNA [15].
