The criteria for the EE-element. Criteria for the EE-element are as follow: 1) 2 E-boxes, close to each other, are needed, 2) E1 E-box allows 1 base mismatch, E2 E-box allows 2 base mismatches, 3) the spacing between 2 E-boxes is 6 or 7 bp, and 4) the element is located within 1 kb upstream region from the TSS.
