(E) We used CTCF-binding events available from the ENCODE project (ENCODE Project Consortium, 2011 ) to enquire the relationship between CTCF binding conservation and tissue specificity.
However, our findings highlight a link between in vivo Dichaete binding conservation and motif conservation, suggesting both functional importance of motif density and quality as well as a mechanism by which balancing selection at the sequence level could feed back to maintain functional binding events.
It takes binding conservations and management measures on its members.
These instruments include binding and non-binding Conservation and Management Measures, Plans of Action, and national legislation.
We also examined the presence of Sox motifs within binding intervals and the correlation between sequence conservation and binding conservation.
(B) SoxN-Dam binding intervals that overlap a REDFly CRM are more likely to show two-way binding conservation between D. melanogaster and D. simulans ("D.mel-D.sim") and are less likely to be unique to D. melanogaster than those that do not (p = 2.40e-72).
(A) Dichaete-Dam binding intervals that overlap a REDFly CRM are more likely to show three-way binding conservation between D. melanogaster, D. simulans and D. yakuba ("3-way") and are less likely to be unique to D. melanogaster ("D. mel unique") than those that do not (p = 7.06e-35).
In mammals, there appears to be minimal correlation, if any, between TF binding intensity and their presence at orthologous regions in divergent vertebrate species; however, in flies, TF binding intensity and TF binding conservation appear to correspond closely.
The binding conservation with INH5 further shows that the loop in between the α4- and the α5- helices is not necessary to recognition.
At the sequence level, we identified highly enriched Sox motifs in all sets of binding intervals that showed both density and nucleotide conservation rates correlated with binding conservation.
