In genetics, a promoter is a sequence of DNA to which proteins bind that

These transcription factors bind to the promoters of a specific set of genes. They are not general transcription factors that bind to every promoter complex, but are recruited to a specific sequence on the promoter of a specific gene. There are hundreds of transcription factors in a cell that each bind specifically to a particular DNA sequence In this review, we define the core promoter as the minimal stretch of contiguous DNA sequence that is sufficient to direct accurate initiation of transcription by the RNA polymerase II machinery (for review, see Struhl 1987; Weis and Reinberg 1992; Smale 1994, 1997,2001; Smale et al. 1998; Burke et al. 1998). Sequence-specific DNA binding proteins must quickly bind target sequences, despite the enormously larger amount of nontarget DNA present in cells. RNA polymerases (or associated general transcription factors) are hypothesized to reach promoter sequences by facilitated diffusion (FD).

Describing the variant in relation to a coding DNA reference sequence (for this variant NM_004006.1:c.-128354C>T or NM_000109.3:c.-401C>T) is possible but not really very informative; you do not know how long the 5'UTR is. The cloning of a eucaryotic promoter-regulatory region that functions preferentially in human cells is disclosed. The invention is exemplified by the cloning of a section of the human cytomegalovirus genome comprising a DNA sequence with regulatory and promoter signals and an initiation site for RNA synthesis.

It has been developed as an evolution of simulated transcription factors that interact with sequences in promoter regions. It builds on principles that are common to neural networks and genetic algorithms. 2007-08-12 The sequence of DNA template that is transcribed during promoter escape (ITS; Initially Transcribed Sequence) can affect promoter escape by mechanisms that are not yet fully understood. We employed a highly parallel strategy utilizing Next Generation Sequencing (NGS) to collect data on escape properties of thousands of ITS variants.

Our results show the presence of strong promoter activity in the DNA sequence corresponding to the pim-1 5'-UTR. The promoter sequence on the DNA is different than most genes, which use a thymine and adenine series of nucleotides called a TATA box. The RNA promoter, instead, has a sequence called an upstream control sequence (UCS) that is recognized by a protein called upstream binding factor (UBF).
