In chromatin immunoprecipitation assays, frequencies of SNPs were significantly different in rRNA gene regions immunoprecipitated with the Upstream Binding Factor (UBF) or with PolI, vs that combined with the transcription factor basonuclin.
A 597 bp DNA fragment biotinylated at one end and with two KOPS sites positioned 230 bp upstream was bound by streptavidin and used in FtsK translocation assays.
"Here, within easy hailing distance, pass the boats bound upstream.
Interactions between upstream and downstream bound PTB could result in a looping of the RNA, thereby shielding specific sequences from functionally interacting with both splicing enhancing factors and the spliceosome [22].
CTCF bound upstream of the TSS may thus act as a marker of unidirectional transcription.
Pch was bound upstream part of 11 fimbriae operons and three of them were also bound by Ler.
These upstream regions were bound strongly by FruA-His6 alone, producing a complex whose migration distance suggested more than 1 FruA-His6 was bound.
15, 17, 18 Physical interactions between the multiple TFs bound upstream of every gene may dictate the specific combination of conditions under which the gene will be expressed.
Of 25 genes whose upstream regions are bound by Leu3 in the low activity experiments (p ≤ 1e-3), we observed binding of 24 at high activity (p ≤ 1e-4).
For example, Pch bound upstream of nleC, nleA, nleG8-2, whereas binding to coding regions were observed for espX7, espN, espJ, and espL2.
Its targets argT, livJ and gltI are bound upstream of the ribosome binding site, and the inhibitory activity cannot be directly explained by competition with ribosome binding.
