What is a promoter a binding site for?
Promoters contain specific DNA sequences such as response elements that provide a secure initial binding site for RNA polymerase and for proteins called transcription factors that recruit RNA polymerase.
Where can I find promoter binding sites?
Go to Eukaryotic Promoter database, put in the NCBI accession number for your gene of interest and then search for the transcription factors of your interest for that promoter sequence. Promoter sequence can also be limited (eg. -500 to +100) or extended (-1000 to +1) the way you like.
Are binding sites always close to promoters?
The binding sites for transcription factors are often close to a gene’s promoter. However, they can also be found in other parts of the DNA, sometimes very far away from the promoter, and still affect transcription of the gene.
What is the function of the 5 UTR?
The eukaryotic 5′ untranslated region (UTR) is critical for ribosome recruitment to the mRNA and start codon choice, and plays a major role in the control of translation efficiency and shaping the cellular proteome.
How do you find the promoter region of a gene?
To find the promoter region, use Map Viewer to locate the gene within a chromosomal context. Then increase the value of the coordinates that surround the gene to a larger sequence that includes the promoter.
What is TF motif?
We define TF binding motifs as sets of DNA sequences having high affinity for binding TFs. Each occurrence of a sequence from the binding motif in a genomic region is referred to as a motif instance.
Is TATA box on the template strand?
The TATA box, which was the first eukaryotic core promoter element identified, has the consensus sequence TATATAAG (nontemplate strand) and is centered approximately 29 bp upstream of the transcription start site.
What is a transcription binding site?
Transcription Factor Binding Sites (TFBSs) Transcription factors (TFs) are proteins with DNA binding activity that are involved in the regulation of transcription. Generally, TFs modulate gene expression by binding to gene promoter regions or to distal regions called enhancers.
Why is TATA box the promoter region?
A TATA box is a DNA sequence that indicates where a genetic sequence can be read and decoded. It is a type of promoter sequence, which specifies to other molecules where transcription begins. Transcription is a process that produces an RNA molecule from a DNA sequence.
What is image-based promoter prediction?
Image-based promoter prediction: a promoter prediction method based on evolutionarily generated patterns. Sci Rep8:17695. doi:10.1038/s41598-018-36308-0.
Do starting protein structures affect binding-site prediction results?
We probe the influence of starting protein structures on the results of binding-site prediction, so the dataset contains a minimum of two ligand-bound and two ligand-free structures for each protein.
What is the new prokaryote promoter prediction tool?
A new prokaryote promoter prediction tool was developed and is based on PWMs and Hidden Markov Models (HMMs) of −35 and −10 consensus sequences and various sigma factor binding sites. PWMs and HMMs of B. subtilis and E. coli promoters are used as reference for Gram-positive and Gram-negative bacteria, respectively.
Is it possible to predict promoters/TSSs at specific genes or genomic levels?
Therefore, diverse computational tools have been created to predict promoters/TSSs at specific genes or genomic levels.
