Figure 3. Effect of KIR promoter polymorphisms on Sp1 binding.

Figure 3

EMSA analysis of the Sp1 binding region corresponding to the polymorphisms observed in KIR alleles. (A) Oligonucleotides used for EMSA. The sense strand of oligonucleotide probes corresponding to the predicted Sp1-binding region of the indicated KIR genes is shown. The nucleotide residue labeled (−26) corresponds to the same −26 position shown in Figure 2A. (B) EMSA analysis performed on YT nuclear extracts with probes indicated in A. The right panel shows a supershift of the Sp1 consensus probe from YT extracts or in the presence of recombinant human Sp1 protein (rhSp1).
