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: 5406

"This gene encodes a member of the lipase family of proteins. The encoded enzyme is secreted by the pancreas and hydrolyzes triglycerides in the small intestine, and is essential for the efficient digestion of dietary fats. Inhibition of the encoded enzyme may prevent high-fat diet-induced obesity in mice and result in weight loss in human patients with obesity. Mutations in this gene cause congenital pancreatic lipase deficiency, a rare disorder characterized by steatorrhea."[7]

Gene ID: 5408

"This gene encodes a lipase that hydrolyzes galactolipids, the main components of plant membrane lipids. An allelic polymorphism in this gene results in both coding and non-coding variants; the reference genome represents the non-coding allele."[8]

Gene ID: 8513

"This gene encodes gastric lipase, an enzyme involved in the digestion of dietary triglycerides in the gastrointestinal tract, and responsible for 30% of fat digestion processes occurring in human. It is secreted by gastric chief cells in the fundic mucosa of the stomach, and it hydrolyzes the ester bonds of triglycerides under acidic pH conditions. The gene is a member of a conserved gene family of lipases that play distinct roles in neutral lipid metabolism. Several transcript variants encoding different isoforms have been found for this gene."[9]
