Fig. 1.
Promoter structure of human β2m.
Schematic representation of the promoter of β2m, depicting the position and order of the E box, ISRE, and κB site. Underneath, the nucleotide sequence of the upstream region of β2m containing the 3 boxes is shown, indicating the mutations in the putative E box, Ets/ISRE, and κB site that are introduced for the mutant promoter constructs. Human β2m promoter region accession numberAF092744.
