Disease relevance of CP

  • The internal ribosome entry sites (IRES), IRES(CP,148)(CR) and IRES(MP,75)(CR), precede the coat protein (CP) and movement protein (MP) genes of crucifer-infecting tobamovirus (crTMV), respectively [1].
  • Expression of tobacco mosaic virus (TMV) coat protein (CP) in plants confers resistance to infection by TMV and related tobamoviruses [2].
  • The replacement of the CP gene in RNA 3 by a mutant gene encoding a CP defective in virion formation did not affect cell-to-cell transport of the chimera's with a functional MP [3].
  • The activities of the bromovirus 3a proteins were enhanced by coexpression of the cognate CP but the activity of CMV 3a Delta C33 was not [4].
  • Complementation of movement-deficient potato virus X (PVX) coat protein (CP) mutants, namely PVX.CP-Xho lacking the 18 C-terminal amino acid residues and PVX.DeltaCP lacking the entire CP gene, was studied by transient co-expression with heterologous proteins [5].
 

High impact information on CP

  • The results suggest that wt CP has a positive effect on the production of MP, whereas the CP(T42W) has a negative effect on MP accumulation and/or function [2].
  • It was previously shown that, unlike the type member of the genus Tobamovirus (TMV U1), a crucifer-infecting tobamovirus (crTMV) contains a 148 nt internal ribosome entry site (IRES)(CP,148)(CR) upstream of the coat protein (CP) gene [6].
  • (ii) "deltaNPT-CP" transcripts contained partially truncated neomycin phosphotransferase I gene and CP gene [7].
  • Frameshift mutations designed to cause premature termination of translation were introduced into either the 30-kDa movement protein (MP) gene or the coat protein (CP) gene [8].
  • Phylogenetic analysis of these CP ORFs resulted in a tree with three clusters each containing at least one of the approved species RMV, TVCV and 1ptYoMV/WMoV in which our isolates were distributed [9].
 

Biological context of CP

  • The 126/183-kDa RNA-dependent RNA polymerase (RdRp), 33-kDa movement protein (MP) and 18-kDa coat protein (CP) cistrons are located at nt 63-3401/4901, 4807-5718, and 5721-6197 on the genome, respectively [10].
  • An environmentally safe Tobacco Mosaic Virus (TMV)-based expression replicon was constructed that lacks movement protein (MP) and coat protein (CP), and which expresses the green fluorescent protein (GFP) gene from a full CP subgenomic promoter [11].
  • The nucleotide and amino acid sequences of the CP of CMMoV were 39.6% to 49.2% and 25.8% to 40.3% identical to other seventeen tobamoviruses, respectively [12].
  • In this study, a TMV-based vector was designed such that a fragment encoding 15 amino acids of the poliovirus peptide (PVP) derived from the viral capsid proteins VP3 and VP1 of poliovirus type 1 Sabin was inserted downstream of the six-base 3' context nucleotide sequence of the TMV coat protein (CP) gene [13].
