TATA box aquaporin family

Jump to navigation Jump to search

The TATA box (also called Goldberg-Hogness box)[1] is a DNA sequence (cis-regulatory element) found in the promoter region of genes in archaea and eukaryotes;[2] approximately 24% of human genes contain a TATA box within the core promoter.[3]

Human genes

"TATA-containing genes are more often highly regulated, such as by biotic or stress stimuli."[4] Only "∼10% of these TATA-containing promoters have the canonical TATA box (TATAWAWR)."[4]

"SRF-regulated genes of the actin/cytoskeleton/contractile family tend to have a TATA box."[5]

Different "TATA box sequences have different abilities to convey the activating signals of certain enhancers and activators in mammalian cells [...] and in yeast [...]."[5]

"SRF is a well established master regulator of the specific family of genes encoding the actin cytoskeleton and contractile apparatus [...], and we found that ~40% of the core promoters for these genes contain a TATA box, which is a significant enrichment compared to the low overall frequency of TATA-containing promoters in human and mouse genomes (...)."[5] "Global frequencies of core promoter types for human [9010 orthologous mouse-human promoter pairs with 1848 TATA-containing or 7162 TATA-less][6] genes with experimentally validated transcription start sites [are known from 2006]."[5] "The TATA box [...] has a consensus sequence of TATAWAAR [...]."[5] W = A or T and R = A or G. We "estimate that ~17% of promoters contain a TATA box".[6]

Gene ID: 358

"This gene encodes a small integral membrane protein with six bilayer spanning domains that functions as a water channel protein. This protein permits passive transport of water along an osmotic gradient. This gene is a possible candidate for disorders involving imbalance in ocular fluid movement."[7]

Gene ID: 359

"This gene encodes a water channel protein located in the kidney collecting tubule. It belongs to the MIP/aquaporin family, some members of which are clustered together on chromosome 12q13. Mutations in this gene have been linked to autosomal dominant and recessive forms of nephrogenic diabetes insipidus."[8]

Gene ID: 360

"This gene encodes the water channel protein aquaporin 3. Aquaporins are a family of small integral membrane proteins related to the major intrinsic protein, also known as aquaporin 0. Aquaporin 3 is localized at the basal lateral membranes of collecting duct cells in the kidney. In addition to its water channel function, aquaporin 3 has been found to facilitate the transport of nonionic small solutes such as urea and glycerol, but to a smaller degree. It has been suggested that water channels can be functionally heterogeneous and possess water and solute permeation mechanisms. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms."[9]

Gene ID: 4284

"Major intrinsic protein is a member of the water-transporting aquaporins as well as the original member of the MIP family of channel proteins. The function of the fiber cell membrane protein encoded by this gene is undetermined, yet this protein is speculated to play a role in intracellular communication. The MIP protein is expressed in the ocular lens and is required for correct lens function. This gene has been mapped among aquaporins AQP2, AQP5, and AQP6, in a potential gene cluster at 12q13."[10]
