Ets2 binds to the endogenous Nab2 promoter. Cross-linked chromatin from the S16Y Schwann cell line was immunoprecipitated with Ets2 antibody (filled bars) or purified control IgG (open bars). Percentage recovery relative to input DNA was determined for IMG2A, Nab1, and several Nab2 primer sets as indicated in the diagram. Potential ETS binding sites identified by sequence analysis are shown as filled rectangles. Primer set 3 was used in previous figures to detect Egr2 binding.
