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

Main article: 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: 3182

"This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are produced by RNA polymerase II and are components of the heterogeneous nuclear RNA (hnRNA) complexes. They are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene, which binds to one of the components of the multiprotein editosome complex, has two repeats of quasi-RRM (RNA recognition motif) domains that bind to RNAs. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene."[7]

Gene ID: 3183

"This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene can act as a tetramer and is involved in the assembly of 40S hnRNP particles. Multiple transcript variants encoding at least two different isoforms have been described for this gene."[8]

This gene does not have a TATA box in its core promoter but does have a BRE- and a DPE+.[6]
