Webb4 jan. 2001 · Construct 1B, the HIS3 promoter (indicated by the small right arrow) was located immediately adjacent to the telomere repeat and is 300 ± 75 bp from the end of the chromosome 22. The HIS3 gene ... WebbThe cells are transformed with two low-copy plasmids: one expressing mammalian p53 through the yeast ADH1 constitutive promoter and the other a reporter with p53-binding sites driving the HIS3 gene . In the genetic background used here only cells expressing the reporter gene will grow in the absence of histidine, reflecting p53-dependent activation …
Mutations in Escherichia coli's analogous gene, hisB allows researchers to select only those individuals expressing the HIS3 gene included on a plasmid. The HIS3 gene is coupled to a certain promoter which can only be activated by successful binding of the relevant transcription factors. This is used in certain methods of bacterial two-hybrid screening to allow the survival of E. coli in which a desired protein-DNA or protein-protein interaction is taking place. Webb1 sep. 2004 · The mhis3AI gene carries a HIS3 promoter but produces an inactive protein due to the inserted intron. Induction of Ty1 transcription in galactose-containing medium produces a Ty1 mRNA containing an intron, which is subsequently spliced out. This message now contains, ...

Webb1 nov. 1998 · Loss of this interaction either through abrogation of Not2 N-terminal function or deletion of ada2 or gcn5 results in derepression of the HIS3 TC element. This suggests that association of Not2 with the Ada/Gcn5 histone acetyltransferase complex is involved in regulation of the HIS3 promoter. boca north boca grande flWebbDeletions retaining greater than 155 base pairs before the mRNA coding sequences are phenotypically indistinguishable from the wild-type his3 allele.
