Genome-wide association studies identified ADAMTS7 as a risk locus for coronary artery disease. In carotid arteries of rats, neointima formation after balloon-mediated injury goes along with enhanced Adamts7 expression. Vice versa, Adamts7-deficient mice display reduced neointima formation following vascular injury. Although a causal link between ADAMTS7 and coronary artery disease remains to be proven, inhibition of ADAMTS7 represents a potential new target for intervention in this disease. ADAMTS7, a member of the â€'a disintegrin and metalloproteinase with thrombospondin motifs' (ADAMTS) family of proteins, contains a catalytic zinc ion in the binding site of its metalloproteinase domain. The structure of ADAMTS7 and its inhibitors are unknown. In this study, we used in silico methods, including homology modeling and pharmacophore modeling, to analyze the ADAMTS7 metalloproteinase domain, particularly its binding site. The results revealed structural and sequence differences relative to the binding sites of the other ADAMTS proteins; these non-conserved regions represent potential binding regions for selective ADAMTS7 inhibitors. The main contribution of this study is the proposal of a pharmacophore for ADAMTS7. The characterization of the ADAMTS7 binding site and definition of a pharmacophore are the first step toward developing a new therapeutic target for coronary artery disease.
