Example sentences for: initiator

How can you use “initiator” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Several lines of evidence suggest that the SCF pathway is also conserved in the fission yeast Schizosaccharomyces pombe . Pcu1p, a Cdc53p/CUL1-related protein, was shown to associate with two different F-box/WD repeat proteins, Pop1p and Pop2p, when overexpressed [ 18 ] . In addition, genetic studies demonstrated that both of these F-box proteins are simultaneously required for efficient destruction of Rum1p and the replication initiator Cdc18p [ 18 19 20 ] . Rum1p is a Sic1p-analogous CDK inhibitor, which accumulates in G1, but is degraded as cells enter S phase [ 21 22 ] . Failure to degrade Rum1p is the major phenotypic defect of pop1 and pop2 deletion strains, which leads to disturbance of normal cell cycle progression, resulting in polyploidy [ 18 19 20 23 ] . Based on the genetic data and the biochemical observation that Pop1p and Pop2p interact when overexpressed, a putative SCF Pop1p-Pop2pcomplex was proposed, which would contain the heterooligomerizing F-box proteins Pop1p and Pop2p bound to SCF core components [ 18 20 ] .

  • The sequence immediately flanking the dnaA gene is considered the origin of chromosomal replication, or oriC region [ 9 10 ] . This region contains several genes that encode proteins required for basic cellular functions, including the protein subunit of RNase P (RnpA), ribosomal protein L34 (RpmH), the replication initiator protein (DnaA), the beta subunit of DNA polymerase III (DnaN), the recombination repair protein RecF, and the DNA gyrase proteins GyrA and GyrB.

  • Note that the initiator and TATA box are no longer identified, owing to the background model and the extended sequences, but that some of the other core motifs of Table 2are still highly statistically significant.

  • Of the various cytokines tested (TNFα, IFNγ, or sFasL), TNFα was the only potent initiator of CLENDO cell death.

  • The Ymut2 site, which is the most important site for controlling basal expression, overlaps a potential initiator site fitting the consensus (5' CTT CCC TTT TCC 3') for the ribosomal protein Inr family with only one mismatched base [ 40].
