      Background InformationMatrix metalloproteinase 9 (MMP-9), a member of the peptidase M10A family, is a multidomain zinc metalloproteinase enzyme, which is highly expressed in neurons and glia of the hippocampus, cerebral cortex, and cerebellum. The active MMP-9 is formed upon cell stimulation by enzymatic cleavage of the precursor, proMMP-9. Because of its function in tissue degradation, MMP-9 is tightly regulated by multiple mechanisms, including glycosylation, inhibition by TIMP1, internalization, and sequestration. MMP-9 plays an important role in long-term potentiation, synaptic plasticity, and memory. Several studies have reported an increase in levels of MMP-9 after CNS injury, as well during the development of various cancers.

      Molecular Weight~67 kDa observed. Under reducing conditions in SDS-PAGE, MMP-9 monomer (proenzyme) is observed as a major band at ~ 92 kDa. Activation of MMP-9 proenzyme with trypsin yields different active forms at ~64, ~67, and ~82 kDa in a time dependent manner (Duncan, M. E., et al. 1998. Eur J Biochem. 258(1):37-43).
