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.

Function

MMP9_HUMAN May play an essential role in local proteolysis of the extracellular matrix and in leukocyte migration. Could play a role in bone osteoclastic resorption. Cleaves KiSS1 at a Gly-|-Leu bond. Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide.^[2]

Publication Abstract from PubMed

Matrix metalloproteinases (MMPs) are a large family of zinc-dependent endoproteases that catalyze cleavage of extracellular matrix and nonmatrix proteins. MMPs play a role in tissue remodeling, and their uncontrolled activity is associated with number of diseases, including tumor metastasis. Thus, there is a need to develop methods to monitor MMP activity, and number of probes has been previously described. The key problem many probes encounter is the issue of selectivity, since 23 human MMPs, despite playing different physiological roles, have structurally similar active sites. Here, we introduce the halogen bonding concept into the probe design and show that the probe containing iodine exhibits an unprecedented selectivity for MMP-9. We provide structure-based explanation for the selectivity, confirming that it is due to formation of the halogen bond that supports catalysis, and we highlight the value of exploring halogen bonding in the context of selective probe design.
