Disease
MMP9_HUMAN Defects in MMP9 may be a cause of susceptibility to intervertebral disc disease (IDD) [MIM:603932; also known as lumbar disk herniation (LDH). IDD is one of the most common musculo-skeletal disorders and the predominant cause of low-back pain and unilateral leg pain.[1] Defects in MMP9 are the cause of metaphyseal anadysplasia type 2 (MANDP2) [MIM:613073. Metaphyseal anadysplasia consists of an abnormal bone development characterized by severe skeletal changes that, in contrast with the progressive course of most other skeletal dysplasias, resolve spontaneously with age. Clinical characteristics are evident from the first months of life and include slight shortness of stature and a mild varus deformity of the legs. Patients attain a normal stature in adolescence and show improvement or complete resolution of varus deformity of the legs and rhizomelic micromelia.

Publication Abstract from PubMed
Matrix metalloproteinase 9 (MMP9) is a key regulator of the extracellular matrix (ECM), involved in the degradation of various ECM proteins. MMP9 is a member of a large family of proteases that are secreted as inactive zymogens. MMP9 plays a pathological role in a variety of inflammatory and oncology disorders and has long been considered an attractive therapeutic target. GS-5745 is a potent, highly selective humanized monoclonal antibody inhibitor of MMP9 that has shown promise in treating ulcerative colitis and gastric cancer. Here we describe the crystal structure of GS-5745:MMP9 complex and biochemical studies to elucidate the mechanism of GS-5745 inhibition of MMP9. GS-5745 binds MMP9 distal to the active site, near the junction between the prodomain and catalytic domain. GS-5745 inhibits MMP9 by two mechanisms: binding to active MMP9 allosterically inhibits MMP9 activity and binding to pro-MMP9 prevents MMP9 activation.
