The ankylosing spondylitis (AS)-risk allele at rs11209032 alters DNA-protein complex formation. Chemiluminescent electrophoretic mobility shift assay (EMSA) showing complex formation (i) after addition of HEK293 nuclear extract (lanes 2 and 7), and competition with 100-fold excess of unlabelled probes (lanes 3 and 8). TWIST1 antibody addition leads to a reduction or inhibition of the complex (i) (lanes 4 and 9, respectively). Addition of nonspecific IgG antibody (lanes 5 and 10). NE, nuclear extract; pro, protective. This result was confirmed in five independent experiments.
