TATA box
The TATA box was first identified in 1978 as a component of eukaryotic promoters. Transcription is initiated at the TATA box in TATA-containing genes. The TATA box is the binding site of the TATA-binding protein (TBP) and other transcription factors in some eukaryotic genes. Gene transcription by RNA polymerase II depends on the regulation of the core promoter by long-range regulatory elements such as enhancers and silencers. Without proper regulation of transcription, eukaryotic organisms would not be able to properly respond to their environment.
