TATA box sequence variation in natural pol II cellular promoters
| Nucleotide | Occurrence (%)a at TATA box position:
|
||||||
|---|---|---|---|---|---|---|---|
| T (+1) | A (+2) | T (+3) | A (+4) | A (+5) | A (+6) | A (+7) | |
| A | 4 | 90 | 1 | 91 | 69 | 93 | 57 |
| C | 12 | 0 | 4 | 0 | 0 | 1 | 1 |
| G | 5 | 1 | 1 | 1 | 0 | 5 | 11 |
| T | 79 | 9 | 94 | 8 | 31 | 1 | 31 |
Occurrence of the four nucleotides in the TATA box at positions 1 to 7, based on 389 TATA box elements, mainly from vertebrate promoters obtained from TRANSFAC 6.0 (29). Boldface indicates the most favored residues.
