Network motifs have also been analyzed in the PPI network of Saccharomyces cerevisiae, and from this, it has been concluded that motif topology is correlated with the conservation of motif proteins; besides this, it has been inferred that motifs probably represent the evolutionary-conserved topological units of cellular networks [ 22].
They compare the evolutionary conservation of motifs to that of randomly chosen network patterns and conclude that motifs are not subject to any particular evolutionary pressure acting for their preservation.
A previous study of E2f1 ChIP-chip data also failed to find a convincing E2f1 motif, concluding that E2f1 is mainly recruited to promoters via a mechanism distinct from recognition and binding to the consensus site (Bieda et al., 2006).
By a closer inspection of Figure 1 we conclude that motifs reported by GRISOTTO- are strongly similar to the ones reported by Chen et al. and MEME-.
From the specific interactions between common (Krek et al., 2005) and TS motif instances, we concluded that the motif instances are organized in a bow-tie structure with specific enrichment of miRNA, TF and non-TF genes in the input, core and output layer (Supplementary Fig. 5.1).
Hence, it could be concluded that 6-[2- R2B phenyl]pyrid-2-ylamido 6-[2- R2B phenyl]pyrid-2-ylamido 6-[2- R2B phenyl]pyrid-2-ylamido 6-[2- R2B phenyl]pyrid-2-ylamido 6-[2- R2B phenyl]pyrid-2-ylamido
We conclude that the motif is highly predictive of MrpC2 binding.
From this, we may conclude that, as motif predictions become stronger, the exact value of t sim becomes less important.
Taking into account that six of these sites are hot spots for "RNA recombination" we conclude that this motif is necessary but not sufficient for the template switching.
40 Instead in Ref. 41, the authors emphasize the importance of modeling RNA secondary structure to recover RBP, and they conclude that RBP motif recovery is a rapidly expanding field but still in its infancy.
Because the change of the AG C/T-typeserines of a SSD unit would require five sequential single basepair changes to become a KSD, it is reasonable to conclude that this motif was probably introduced a single time into the repeat domain and then duplicated along with portions of the SSD repeat by slip replication and/or recombination events.
