MMP9，全名為基質金屬蛋白酶-9，也稱為膠質細胞明膠酶，是一種參與基質降解和組織重塑的酶類分子。最近的研究表明，MMP9在多種癌癥的發生和發展中發揮著重要作用，同時也參與心血管疾病、關節炎等多種疾病的發生和發展。MMP9也成為了治療靶點的研究熱點。

Matrix metalloproteinase that plays 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 NINJ1 to generate the Secreted ninjurin-1 form. 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.
