Disease relevance of ompA

 

High impact information on ompA

  • Effects of ompA Deletion on Expression of Type 1 Fimbriae in Escherichia coli K1 Strain RS218 and on the Association of E. coli with Human Brain Microvascular Endothelial Cells [4].
  • Although close spacing of translating ribosomes is not critical for message stabilization by the ompA 5' UTR, mRNA longevity does require the periodic passage of ribosomes through the protein-coding region [5].
  • These findings imply that the ompA 5' UTR prolongs mRNA longevity by impeding multiple pathways for mRNA degradation [5].
  • This was 50% higher than the best result obtained from plasmid construct lacUV5par8cex, using the lacUV5 promoter and the ompA leader sequence [6].
  • Regulation of ompA by micA may have been retained due to a necessity for ompA control during one or both stages of the P. luminescens life cycle [7].
 

Biological context of ompA

  • Furthermore, real-time PCR analysis indicates that the extent of polyadenylation of individual full-length transcripts such as lpp and ompA varies significantly in wild-type cells [8].
