The "'mSin3 interaction domain "'( SID ) is an interaction domain which is present on several transcriptional repressor proteins including TGF? ( transforming growth factor ? ) and Mad.
32.
It interacts with the paired amphipathic alpha-helix 2 ( PAH2 ) domain of mSin3, a transcriptional repressor domain that is attached to transcription repressor proteins such as the mSin3A corepressor.
33.
In 2013, a combination of cold denaturation and NMR spectroscopy was used to show detailed insights into the unfolding of the " E . faecalis " homodimeric repressor protein CylR2.
34.
The motif is very similar in sequence and structure in a wide range of DNA-binding proteins ( e . g ., cro and repressor proteins, homeotic proteins, etc . ).
35.
The 3'- UTR also has silencer regions which bind to repressor proteins and will inhibit the expression of the mRNA . Many 3'- UTRs also contain AU-rich elements ( AREs ).
36.
At one point, Lu and his colleagues even tried to grow crystals in the zero gravity of space, twice sending a solution of lactose-repressor protein on space shuttle missions, but to no avail.
37.
Then, Phospho-AI-2 binds the transcriptional repressor protein, LsrR, which subsequently is released from the promoter / operator region of the lsr operon and transcription of the " lsr " genes is initiated.
38.
Similar to-leucine } }, ( 2.42 grams ) and-leucine } } ( 3.42 grams ) do not produce statistically distinguishable anabolic effects, as measured by the fractional synthesis of translation repressor protein 4EBP1 ).
39.
Second, to reduce the disparity between the lifetimes of the repressor proteins and the mRNAs, a carboxy terminal tag based on the ssRA RNA sequence was added at the 3'end of each repressor gene.
40.
In the lac operon, lactose binds to the repressor protein and prevents it from repressing gene transcription, while in the trp operon, tryptophan binds to the repressor protein and enables it to repress gene transcription.
