Our study identified regulatory elements with diverse biologically functions that include at least core promoter elements, TF binding sites, and functional RNA sites.

The flexible and the corresponding 1e,4e-disubstituted cyclohexane derivatives were designed in order to investigate the influence of rigidification on 5-HT1A affinity, selectivity for 5-HT2A, 5-HT7, D1, and D2 binding sites and functional profile at pre- and postsynaptic 5-HT1A receptors.
Ngn3, which is the master regulator for the endocrine pancreas, was modeled as activator of the targets Pax4, Arx, Pax6 and MafA based on promoter binding sites and functional evidence [48] since these regulatory relationship may account for activation of the downstream decision circuits.
Mutations do not only affect binding sites and functional sites but, in many cases, they also alter sites that are subject to post-translational modifications, potentially affecting the function of the corresponding proteins.
Thus, although these nAChR subunit knockouts completely eliminate nicotinic agonist binding sites and functional nAChRs, a small amount of a non-functional protein appears to be produced that is able to form some complexes with interacting proteins.
A central coiled-coil domain contains a specific Rab9 binding site, and functional assays indicate that this domain is important for MPR recycling to the Golgi complex.
Having shown a difference in histone modification patterns between functional binding sites and non-functional ones at yeast ORF for almost half of all TFs tested, we investigated whether there is a correlation between the histone modifications at the ORF and the TF bindings to the corresponding promoter.
Both results confirm there is a distinct pattern of histone modifications between functional TF binding sites and non-functional ones for almost half of all TFs tested.
Information on computationally inferred functional TF binding sites and non-functional ones for 37 yeast TFs at normal condition was taken from publication by Gao et al. [ 8].
Conceptually, the interactions between TFs, their binding sites, and their functional targets are represented by gene regulatory networks (GRNs).
