The structure of a complex containing the homeodomain repressor protein MATalpha2 and the MADS-box transcription factor '''MCM1''' bound to DNA has been determined by X-ray crystallography at 2.25 A resolution.

[[MtrF]] is a cell surface cytochrome on the Gram-negative bacteria known as ''Shewanella oneidensis''.<ref name="mtrf"> PMID:11418600</ref> MtrF is involved with shuttling electrons across its (''S. oneidensis'') outer surface. MtrF has several homologues, MtrC and the protein OmcA. These three different proteins are thought to be replaceable with one another in deletion mutation experiments.<ref name= "mtrf" />

Through the structure of this oligomer that was obtained by crystallography, we can see that HDAC9 is kept <scene name='Sandbox_Reserved_1/Binding/3'>relatively far from the genomic DNA </scene> even after MEF2 binding to the chromosome. We can also easily observe a very well <scene name='Sandbox_Reserved_1/Conservation/7'>evolutionary conserved region</scene> near the DNA binding site of MEF2.
