Cell-type dependent binding and the ELK4 cofactor. For SRF binding sites independent of cell type (black squares), binding of SRF and ELK4 at the site is correlated. For cell-type dependent SRF binding sites (grey squares) no correlation is observed. Binding of each factor was determined by quantitative PCR as described (Methods) and is displayed as a log of the enrichment observed at each site compared to a panel of negative controls.
