Specific binding for each pair of sections used for receptor studies was calculated by subtraction of the mean nonspecific binding from the mean total binding using the whole sections as the region of interest.
When we assess interaction strength by employing interaction estimators such as the correlation between the binding profiles of each pair of regulators, Fisher's exact test, the Chi Square test or similar tests for association, we are more likely to identify pairs of strongly interacting regulators for which at least one of the two regulators targets a large number of genes.
Ligand binding data similar to that shown here has been published regarding the binding of another pair of chemokine agonists, CCL5 and CCL3, at the same CC chemokine receptor, CCR1 (Jensen et al., 2008).
Although in these examples single site binding to the 50S subunit is highlighted, we would suggest that such binding was possible originally with pairs of tRNAs positioned in the adjacent A and P sites, thereby enhancing both the binding of the pair to the ancestral peptidyl transferase and the rate of peptide synthesis.
The quality of the two methodologies is judged by the methods' capacity to, among other, correctly predict the similarities in the protein-ligand contact patterns of each pair of binding sites.
We then tested for preferential binding of the AP1/MYC pair, and again saw results consistent with this pair acting in both MET and Non-MET cancer models.
Thus, the binding of an indirect pair is permitted for ν cos3ϕ k >0.
However, at a finite total momentum, the gap opens that makes the binding of the moving pair allowable.
This highly unusual empirical finding can be interpreted as an increase in accessibility of an epitope to its ligand due to conformational changes in the target determinant molecule induced by binding of a paired "stimulatory" ligand to its adjacent epitope.
Chromosome tethering to the nuclear envelope is accompanied by the binding of pairing center-binding zinc finger proteins to pairing centers/homology recognition regions on one end of each chromosome.
