This conjugated urease-DNA (UrD) is used to hybridize to the extended binding region found in the reverse primer.
Recent structural studies on the SUN domain derived from mammalian Sun2 indicated that this region folds into homotrimeric structure, primarily composed of a series of β-sheets that resembles the sugar-binding region found in lectins, suggesting that these proteins share an ancient common ancestor (Burke 2012; Sosa et al. 2012).
For example, the user can merge the binding region calls of experimental replicates, take the intersection of binding regions with promoter regions, take the intersection of sets of ChIP experiments performed with different transcription factors, or easily eliminate binding region calls that overlap with regions found in a control experiment.
Critical regions of SF1 involved in transcriptional regulation include a two zinc finger DNA binding domain (DBD), an "A" box region found in monomeric nuclear receptors, a hinge region, and a helical ligand binding domain (LBD) region containing an activation function 2 (AF–2) domain [ Parker and Schimmer, 1997].
The C-terminal sequence downstream of the Xin repeats contains many proline-rich regions and a filamin c-binding region was found in the last 158 aa residues of a minor and largest isoform of hXinα [1], [5], [10].
In addition, by analyzing binding motifs found in TCF4 binding regions we were able to identify known and potentially novel transcription factors that interact with TCF4 (Figure S1 and Figure S2).
In the phosphine-resistant population, insects unexposed or exposed to phosphine had the polymorphism P45S in the N-terminal FAD binding region of DLD, found in 315/455 (69.2 %) transcripts from the unexposed insects, and 352/546 (64.5 %) transcripts from the phosphine-exposed insects (Fig. 1b).
However, the majority of binding sites are found in regions of previously accessible chromatin, indicating that (1) RUNX1/Etargetsets binding sites that are destined for differentiation-driven factor exchange, and (2) shortly after its upregulation, C/EBPα resumes its original binding behavior and reorganizes existing transcription factor assemblies to drive myelopoiesis.
Similarly, one major invariable site of HP1 binding was found in euchromatic region 31 of the 2L arm in D. melanogaster [ 61].
