This is because, only a very small percentage of binding sites are available to bind to interact with the transcription factors, as mentioned earlier in the limitation of regulatory networks section.
Interestingly, the coactivators P300 and PCAF, although directly bound to E47, can interact with LMO2 independently of its association with SCL E47.
This region, which is disordered in the X-ray models where an abasic site-containing DNA is bound to Fpg, interacts tightly with the 8-oxoG which appears to be confined within the enzyme.
ACCO/Fe(II) and ACCO/Fe(II)/HCO3− are 6-coordinate and bicarbonate bound to Arg175 interacting with ACCO/Fe(II) would account for the NIR CD titration results of Zhou et al. (2002).
The Pan3 homodimer binds a single Pan2 chain, and the crystal structure of ctPan3 bound to the interacting linker region of ctPan2 (residues 355 406) shows an extensive interface between the two subunits consistent with the integral role of Pan3 in the overall function of the complex.
Thus, we expected the majority of CUGBP1 bound mRNAs to interact with CUGBP1 through their UTRs.
First, we added the synergy to the model by allowing several DNA bound activators to interact with the basal transcription machinery (BTM) simultaneously ("multiplicative effect" model).
Other improvements include the addition of synergy by allowing several DNA bound activators to interact with the BTM simultaneously, dual action of TF Hb on gene Kr or dual regulatory interactions between hb and Kr.
Gtr1, particularly when bound to GTP, physically interacts with Tco89 and Kog1, and this interaction is reduced by leucine starvation (Binda et al., 2009).
Both genetic and biochemical evidence indicates that Gtr1, particularly when bound to GTP, physically interacts with the TORC1 components, Tco89 and Kog1, and this interaction is diminished under leucine starvation.
