FIG 7 .

Molecular structure of MFS1 promoter genotypes. The figures indicate the location, length, and insert sites of MFS1 promoter inserts. Repeats between both insertion sites are indicated by boldface letters. Consensus sequences of potential regulatory elements identified by TRANSFAC searches (44) are indicated by the colored triangles and boxes. Repeats of longer sequences, found using mreps (45), are indicated by the black arrows. The MCB element (MluI cell cycle box) regulates the expression of genes involved in G₁-phase transition (46). HNF3 is a Rattus norvegicus motif (87, 88). The hexamer TTAGGG corresponds to the S. cerevisiae TBF1 element (89).
