Figure 3. The conserved MEF2 and NKX2-5 protein-protein interaction interface in two crystal forms.

Figure 3.

(a) Direct protein-protein interaction interface between MEF2 and NKX2-5 from symmetry related complexes. (b) Detailed interactions of residues involved in the protein-protein interaction interface. Dashed line indicates hydrogen bonds. (c) MEF2 and NKX2-5 protein-protein interaction interface represented in surface mode. H3: MEF2 helix 3. H2: NKX2-5 helix 2.
