Comments concerning this interaction

soul and tap were mixed with biotin labeled DNA conjugated to streptavidin-HRP and a chemiluminescent substrate was used for detection. DNA-protein complexes observed by EMSA were used to deduce protein-protein interactions.

soul and tap bind DNA cooperatively; neither binds DNA on its own in this assay.

Interaction in vitro; proteins produced and purified from transfected constructs.
