repressor proteins การใช้

• This gene encodes one member of a family of translation repressor proteins.
• The specific binding site for the Lac-repressor protein is the operator.
• The Nanos protein is a translational repressor protein.
• During normal growth, the SOS genes are negatively regulated by LexA repressor protein dimers.
• The tetracycline repressor protein ( TetR ).
• These act by silencers bind repressor proteins and make the DNA less available for RNA polymerase.
• For example, some repressor proteins can bind to the core promoter to prevent polymerase binding.
• The degree of repression is determined by the concentrations of the repressor protein and corepressor level.
• In the case of the Ifg2 and H19 genes, CTCF, a transcriptional repressor protein, is involved.
• The eggs of P strain females contain high amounts of a repressor protein that prevents transcription of the transposase gene.
• These ncRNAs act by sequestering translational repressor proteins, called expression of downstream genes that would normally be blocked by the repressors.
• Activator of apoptosis Hrk regulates apoptosis through interaction with death-repressor proteins Bcl-2 and Bcl-X ( L ).
• This often occurs when hormone binding to hormone receptors stimulates ubiquitin-associated degradation of repressor proteins that block expression of certain genes.
• But those so-called repressor proteins are designed to have an affinity for a specific chemical, in this case the antibiotic tetracycline.
• The repressor protein MetJ, in cooperation with the corepressor protein S-adenosyl-methionine, mediates the repression of methionine s biosynthetic pathway.
• At this point, due to its recent discovery, it is not yet known if it is regulated by co-repressor protein complexes.
• The problem with the lactose-repressor protein, however, was that it was so huge and so wiggly that it seemed impossible to crystallize.
• Not always included within the operon, but important in its function is a regulatory gene, a constantly expressed gene which codes for repressor proteins.
• This is because the non-specific DNA acts as sort of a " sink " for the repressor proteins, distracting them from the operator.
• The eggs of M strain mothers, which do not contain the repressor protein, allow for transposition of P elements from the sperm of fathers.
