Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5' region of the sense strand). Promoters can be about 100–1000 base pairs long, the sequence of which is highly dependent on the gene and product of transcription, type or class of RNA polymerase recruited to the site, and species of organism ...
5-HTTLPR (serotonin-transporter-linked promoter region) is a degenerate repeat (redundancy in the genetic code) polymorphic region in SLC6A4, the gene that codes for the serotonin transporter. Since the polymorphism was identified in the middle of the 1990s, [ 1 ] [ 2 ] it has been extensively investigated, e.g., in connection with ...
Further research at the late stage of thymocyte development reveals that distal Lck promoter with driven Cre will result in the distal lck gene promoter to drive Cre expression to be limited within innate-like T cells. There is a cell type specific function in innate-like T cells based on the distal lck promoter - driven Cre. [3]
In eukaryotes, the 5′ flanking region has a complex set of regulatory elements such as enhancers, silencers, and promoters. The primary promoter element in eukaryotes is the TATA box. Other promoter elements found in eukaryotic 5′ flanking regions include initiator elements, downstream core promoter element, CAAT box, and the GC box. [1]
Promoter activity of the P-RM and P-R promoters vs RNA polymerase concentration in the enterobacteriophage lambda [1]. Promoter activity is a term that encompasses several meanings around the process of gene expression from regulatory sequences —promoters [2] and enhancers. [3]
The Inr element for core promoters was found to be more prevalent than the TATA box in eukaryotic promoter domains. [9] In a study of 1800+ distinct human promoter sequences it was found that 49% contain the Inr element while 21.8% contain the TATA box. [9] Out of those sequences with the TATA box, 62% contained the Inr element as well.
In molecular biology, a downstream promoter element (DPE) is a core promoter element. Like all core promoters, the DPE plays an important role in the initiation of gene transcription by RNA polymerase II. The DPE was first described by T. W. Burke and James T. Kadonaga in Drosophila melanogaster at the University of California, San Diego in ...
Psychology refers to the study of subconscious and conscious activities, such as emotions and thoughts. It is a field of study that bridges the scientific and social sciences and has a huge reach. It is a field of study that bridges the scientific and social sciences and has a huge reach.
