It is a complex multifunctional molecular machine which, unlike other DNA-binding proteins, engages in extensive and dynamic interactions (both specific and nonspecific) with DNA, and maintains them over a distance. 2007-12-01 The promoter is recognized by RNA polymerase and an associated sigma factor, which in turn are often brought to the promoter DNA by an activator protein's binding to its own DNA binding site nearby. In eukaryotes The process is more complicated, and at least seven different factors are necessary for the binding of an RNA polymerase II to the A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein. The ability of a promoter to initiate transcription is important for the control of gene expression.

In eukaryotes The process is more complicated, and at least seven different factors are necessary for the binding of an RNA polymerase II to the Definition A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein. The DNA polymerase beta promoter-directed CAT expression was competitively inhibited by the simultaneous transfection of plasmid DNA containing SV40 early promoter sequence. The viral sequences which are competitive to the GC-box of DNA polymerase beta gene promoter were the GC-boxes of SV40 promoter.

Smeekens SP, Romano LJ. T7 RNA polymerase plays an important role in both the transcription and replication of bacteriophage T7. Transcription initiation requires formation of the open promoter complex (RPo). To generate RPo, RNA polymerase (RNAP) unwinds the DNA duplex to form the transcription bubble and loads the DNA into the RNAP active site. RPo formation is a multi-step process with transient intermediates of unknown structure. mRNA production and processingaspects of Transcription T7 polymerase is extremely promoter -specific and transcribes only DNA downstream of a T7 promoter. The T7 polymerase also requires a double stranded DNA template and Mg 2+ ion as cofactor for the synthesis of RNA. It has a very low error rate.

Control of this promoter binding step is a key mechanism by which gene expression is regulated (3). TFAM is an abundant protein that binds and bends promoter DNA 15-40 base pairs upstream of the transcription start site, and stimulates the recruitment of mtRNAP and TFB2M to the promoter.
