Figure 2From: SP1 enhances Zbtb7A gene expression via direct binding to GC box in HePG2 cellsSearching for potential cis-elements in the 1000 bp Zbtb7Apromoter. A, The core promoter contains consensus sequences for binding transcription factor Sp1(bold and underlined); B, Mutation analysis of the Sp1-binding sites in the Zbtb7Apromoter. Two mutants were constructed and used for transient promoter assays.Back to article page
