This program was used to search for common TF binding motifs, derived from postion based matrices from the TRANSFACR database.
Ellison and Bachtrog had previously found that the binding motifs derived from transposable elements on the neo-X chromosome are suboptimal (Ellison and Bachtrog, 2013).
We next searched the 4679 fooprints identified at q-value <0.05 for sequences that match the TF binding motifs derived from in vivo ChIP-Chip experiments by MacIsaac et al. (2006) and those derived from in vitro protein-binding microarray (PBM) experiments by Zhu et al. (2009).
We identified TF-mediated transcriptional modules using our method as well as the three other methods, based on the same set of data of microarray (from both cell cycle and stress response), ChIP-chip and TF binding motifs derived from the yeast (see Section 2.3).
TALENs 1,2,3: transcription activator-like effector nucleases (TALENs) are restriction enzymes generated by fusing a DNA-cleavage domain and a domain of a collection of nucleotide-binding motifs derived from TALE proteins.
To identify novel, STAT3-selective inhibitors suitable for interrogating STAT3 signaling in tumor cells, we explored the design of hybrid molecules by conjugating a known STAT3 inhibitory peptidomimetic, ISS610 to the high-affinity STAT3-binding peptide motif derived from the ILR/gp-130.
We evaluated each of the motifs on independent data sets (e.g., asking whether a motif derived from in vivo binding data is consistent with in vitro binding data or with the effects of TF perturbation on gene expression) and manually examined the results, as well as the literature on the protein of interest.
The consensus sequence of the embryo1 motif (TTAATTT) is the same as the Ubx motif derived from in vivo validated Ubx binding sites [5].
One commonly employed biochemical cue is Arg-Gly-Asp (RGD), a short peptide motif derived from the active sites of extracellular matrix (ECM) proteins specific for cell binding.
Initially, we analyzed potential AtoC binding to the hits of the qualified promoter sets and subsequently to additional hits of the motif derived from each execution.
