Proximity-enabled copper phenanthroline cross-linking of IpaB TM1 residues. Gel shift of copper 1,10-phenanthroline cross-linking of membrane-embedded IpaB. Representative Western blots are shown. The positions of IpaB (IpaB) and cross-linked IpaB (IpaB dimer) are shown to the right of the gel. The positions of size markers (in kilodaltons) are shown to the left of the gel.
