Human genes

"TATA-containing genes are more often highly regulated, such as by biotic or stress stimuli."[1] Only "∼10% of these TATA-containing promoters have the canonical TATA box (TATAWAWR)."[1]

"SRF-regulated genes of the actin/cytoskeleton/contractile family tend to have a TATA box."[2]

Different "TATA box sequences have different abilities to convey the activating signals of certain enhancers and activators in mammalian cells [...] and in yeast [...]."[2]

"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 (...)."[2] "Global frequencies of core promoter types for human [9010 orthologous mouse-human promoter pairs with 1848 TATA-containing or 7162 TATA-less][3] genes with experimentally validated transcription start sites [are known from 2006]."[2] "The TATA box [...] has a consensus sequence of TATAWAAR [...]."[2] W = A or T and R = A or G. We "estimate that ~17% of promoters contain a TATA box".[3]

Gene ID: 3848

"The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in the spinous and granular layers of the epidermis with family member KRT10 and mutations in these genes have been associated with bullous congenital ichthyosiform erythroderma. The type II cytokeratins are clustered in a region of chromosome 12q12-q13."[4]

Gene ID: 3858

"This gene encodes a member of the type I (acidic) cytokeratin family, which belongs to the superfamily of intermediate filament (IF) proteins. Keratins are heteropolymeric structural proteins which form the intermediate filament. These filaments, along with actin microfilaments and microtubules, compose the cytoskeleton of epithelial cells. Mutations in this gene are associated with epidermolytic hyperkeratosis. This gene is located within a cluster of keratin family members on chromosome 17q21."[5]

Gene ID: 3859

"KRT12 encodes the type I intermediate filament chain keratin 12, expressed in corneal epithelia. Mutations in this gene lead to Meesmann corneal dystrophy."[6]
