Structure of the S100A4Δ8C/MIIA1908-1923 complex. (A) Ribbon diagram of the S100A4Δ8C/MIIA1908-1923 complex showing the S100A4 subunits in green (subunit A) and brown (subunit B) and the MIIA1908-1923 peptide in blue. (B) Refined model of the S100A4Δ8C/MIIA1908-1923 peptide structure. The myosin-IIA peptide (residues Asp1908-Leu1917) is shown in stick representation superimposed onto the Fo-Fc electron density map, contoured at 3.0σ.
