TATA box basic helix-loop-helix 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: 3280

"This protein belongs to the basic helix-loop-helix family of transcription factors. It is a transcriptional repressor of genes that require a bHLH protein for their transcription. The protein has a particular type of basic domain that contains a helix interrupting protein that binds to the N-box rather than the canonical E-box."[7]

Gene ID: 3397

"The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with members of the basic HLH family of transcription factors. The encoded protein has no DNA binding activity and therefore can inhibit the DNA binding and transcriptional activation ability of basic HLH proteins with which it interacts. This protein may play a role in cell growth, senescence, and differentiation. Two transcript variants encoding different isoforms have been found for this gene."[8]

Gene ID: 4618

"The protein encoded by this gene is a probable basic helix-loop-helix (bHLH) DNA binding protein involved in muscle differentiation. The encoded protein likely acts as a heterodimer with another bHLH protein. Defects in this gene are a cause of autosomal dominant centronuclear myopathy (ADCNM)."[9]

Gene ID: 9421

"The protein encoded by this gene belongs to the basic helix-loop-helix family of transcription factors. This gene product is one of two closely related family members, the HAND proteins, which are asymmetrically expressed in the developing ventricular chambers and play an essential role in cardiac morphogenesis. Working in a complementary fashion, they function in the formation of the right ventricle and aortic arch arteries, implicating them as mediators of congenital heart disease. In addition, it has been suggested that this transcription factor may be required for early trophoblast differentiation."[10]

Gene ID: 10215

"This gene encodes a basic helix-loop-helix transcription factor which is expressed in oligodendroglial tumors of the brain. The protein is an essential regulator of ventral neuroectodermal progenitor cell fate. The gene is involved in a chromosomal translocation t(14;21)(q11.2;q22) associated with T-cell acute lymphoblastic leukemia. Its chromosomal location is within a region of chromosome 21 which has been suggested to play a role in learning deficits associated with Down syndrome."[11]
