Nuclear genes in plants that are transcribed by RNA polymerase II are likely to contain an AT-rich sequence, the TATA box, in the proximal region of the promoter. Based on a survey of plant promoter sequences, most plant genes, including those of maize, have a fairly recognizable TATA ...

In addition, the hsp70 promoter but not the metallothionein promoter contains another sequence, the CCAAT box, which is also found in very many genes with disparate patterns of regulation. Both the CCAAT box and the Sp1 box are typically found upstream of the TATA box, as in the metallothionei...
Most promoter regions of genes do not contain a TATA box. In TATA-less genes, transcription factors recognize other promoter sequences and RNA polymerase binds to these instead. Researchers have discovered differences in regulation between genes with the TATA box and those without the TATA box thro...

Hogness等在真核基因中又发现了类似Pribnow框的共同序列，即位于—25～—30 bp处的TATAAAAG，也称TATA框(TATAbox)。基因（遗传因子）是产生一条多肽链或功能RNA所需的全部核苷酸序列。基因支持着生命的基本构造和性能。储存着生命的种族、血型、孕育、生长、凋亡等过程的全部信息。环境和遗传的互相依赖，...
摘要: Definition Synonym Goldberg–Hogness box; Is the core promoter sequence (5′-TATAA-3′) of most genes. In eukaryotes, it represents the DNA binding site of the TATA binding protein during the process of gene transcription. Promoters lacking a TATA box were first found in housekeeping ge...

Many housekeeping genes and the RAS oncogene do not have this sequence (Suzuki Y et al 2001 Genome Res 11:677). In case of the absence of TATA, some other A and T nucleotides may associate with the TATA-box-binding proteins (TBP). A downstream promoter element (DPE) has also been ...
