A wide variety of algorithms have been developed to facilitate detection of promoters in genomic sequence, and promoter prediction is a common element of many gene prediction methods. A promoter region is located before the -35 and -10 Consensus sequences.
Promoter activity. Promoter activity is a term that encompasses several meanings around the process of gene expression from regulatory sequences — promoters [2] and enhancers. [3] Gene expression has been commonly characterized as a measure of how much, how fast, when and where this process happens. [4] Promoters and enhancers are required ...
The TATA box consensus sequence is TATAWAW, where W is either A or T. In molecular biology, the TATA box (also called the Goldberg–Hogness box) [1] is a sequence of DNA found in the core promoter region of genes in archaea and eukaryotes. [2] The bacterial homolog of the TATA box is called the Pribnow box which has a shorter consensus sequence.
DNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription.
Automated software package to annotate eukaryotic genes from RNA-Seq data and associated protein sequences. Eukaryotes. [1] FragGeneScan. Predicting genes in complete genomes and sequencing Reads. Prokaryotes, Metagenomes. [2] ATGpr. Identifies translational initiation sites in cDNA sequences.
High levels of expression of PDGF have been associated with increased cell growth and cancer. The presence of a guanine-rich sequence in the promoter region of PDGF-A has exhibited the ability to form intramolecular parallel G-quadruplex structures and remains suggested to play a role in transcriptional regulation of PDGF-A.
Gene prediction. In computational biology, gene prediction or gene finding refers to the process of identifying the regions of genomic DNA that encode genes. This includes protein-coding genes as well as RNA genes, but may also include prediction of other functional elements such as regulatory regions. Gene finding is one of the first and most ...
Kozak consensus sequence. The Kozak consensus sequence (Kozak consensus or Kozak sequence) is a nucleic acid motif that functions as the protein translation initiation site in most eukaryotic mRNA transcripts. [1] Regarded as the optimum sequence for initiating translation in eukaryotes, the sequence is an integral aspect of protein regulation ...
