New paths identified by GRN expansion were validated by looking for support for the relationship in DNA binding sites and single-gene perturbation studies.
Both species have a single CtrA binding site and a single IHF binding site that differ in both sequence and position.
However, after shifting, the KS statistics between random locations and double strand binding sites and between random sites and single strand binding sites become 0.1905 and 0.1168, respectively, (see Figure 3(c)).
The N1 region regulates the anterior neural plate [ 45]; it features few binding sites that were experimentally validated in mouse (a tandem Lef1 binding site, and a single Fgf binding site [ 45]).
The main advantages of this approach are that it confirms the binding while also indicating the locations of single binding sites and verifying the C-terminus oriented accessibility of protein G molecules on the lattice.
The parts of CDK6 and PI3KR1 (Phosphatidylinositol 3-kinase) 3'UTRs containing miR-29 binding sites, CDK6 miR-29a single binding sites and the miR-29a full complementary sequence were cloned into the pmirGLO Dual Luciferase miRNA target expression vector (Promega) downstream of the luciferase gene (see Additional file 4: Table S1 for primer sequences and oligonucleotides).
However, whereas in the influenza structures, both 3′ and 5′ extremities of the promoter simultaneously bind their separate single-stranded binding sites and form a distal duplex region (with 11 14 of 5′ base pairing with 10 13 of the 3′ end), for LACV polymerase in the crystallized conformation, this appears to be impossible.
Each probe has a double-stranded region containing a protein binding site and two single-stranded tails.
However in this case, in contrast to the CE/Mn2+ mutagenesis experiments presented here, the mutagen has a direct effect on the RNA structure, and therefore selection favored variants that mutated away the EthBr-binding sites, and a single "winner" emerged.
There are seven base pair positions in the predicted marine c-Jun binding site, and 21 corresponding single bp mutations that could alter one of these bases.
