Moreover, DDX3 exerted its transactivation function on p21waf1 / cip1 promoter through an ATPase - dependent but helicase - independent mechanism, and the four Sp1 sites located within the − 123 to − 63 region, relative to
the transcription start site of p21waf1 / cip1 promoter, were essential for the response to DDX3.
Multiple Sp1 sites (Sp1 - 1, Sp1 - 2, Sp1 - 3, and Sp1 - 4) located at − 123 to − 63 related to
transcription start site are essential for the transactivation of DDX3 on p21waf1 / cip1 promoter.
That being said, we generally pick guides by putting the promoter of the gene into a gRNA finder such as WU - CRISPR (6) or our lab's sgRNA scorer 1.0 (7) and picking whichever guides are closest to
the transcription start site (TSS).
This study describes comprehensive polling of
transcription start and termination sites and analysis of previously unidentified full - length complementary DNAs derived from the mouse genome.
A, schematic representation of serial p21waf1 / cip1 promoter — driven luciferase reporters used in transactivation assay: p21 - Luc contains the 2.3 - kb full - length of p21waf1 / cip1 promoter (from − 2,326 to +10 nucleotide related
transcription start site); its derivatives (− 159 / +8) p21 - Luc, (− 123 / +8) p21 - Luc, (− 84 / +8) p21 - Luc, (− 76 / +8) p21 - Luc, (− 63 / +8) p21 - Luc, and (− 56 / +8) p21 - Luc contain a series of deleted promoters of p21waf1 / cip1.

the transcription start.
Next, the distribution of gene
transcription start sites (TSS) nearest to the DAXX ChIP - Seq peaks was analyzed.
We next compared the 5 ′ ends of the OR gene models reconstructed here using Cufflinks, to the proposed
transcription start sites (TSS) reported by Plessy et al. (2012) using nanoCAGE [29].
An imprinting mark region characterized by paternal allele specific methylation has been suggested to reside in a GC - rich region of 400 bp direct repeats starting at -2 kb relative to the H19
transcription start and extending upstream.
A few receptor genes have more than 8 different isoforms (38 VRs and 10 ORs), however in most of these cases this is due to the presence of several
transcription start sites (TSS) or exons that differ in length by just a few nucleotides, so several of the final transcripts differ only very slightly (Figure S7B).
They helped reveal
the transcription start sites and antisense transcripts of microbial species, improving the microbial genome annotation.
Many clones in the set had EST hits, potential CpG islands surrounding
the transcription start sites, and homologies with the human genome.

the transcription start site (+1) of MELK.

the transcription start site largely due to the actions of two negative transcription elongation factors NELF and DSIF (Peterlin and Price, 2006).
The data indicate that the epigenetic response to maternal care involves not only single candidate gene promoters but includes transcriptional and intragenic sequences, as well as those residing distantly from
transcription start sites.
We mapped the methylation state of the promoters of nearly 20 000 genes and 400 microRNAs in triplicate using custom designed 244 K promoter tiling arrays (Agilent technologies) containing probes selected to tile ∼ 1000 bp upstream to ∼ 250 bp downstream of
the transcription start site.

Two components, counterparts of human
transcription factor IIF (TFIIF) and TFIIH, could be exchanged individually between systems without effect on the

start site of
transcription.
