Matrix metalloproteinase-9 (MMP-9), also known as 92 kDa type IV collagenase, 92 kDa gelatinase or gelatinase B (GELB), is a matrixin, a class of enzymes that belong to the zinc - metalloproteinases family involved in the degradation of the extracellular matrix.

神经元MMP-9通过控制树突棘的形状和兴奋性突触的功能参与突触的可塑性，从而在学习、记忆和皮层可塑性中发挥关键作用。

Matrix metalloproteinase (MMP)-9 (Gelatinase B, 92-kD type IV collagenase, EC 3.4.24.35) is an MMP that is present in low quantities in the healthy adult lung, but much more abundant in several lung diseases, including asthma, idiopathic pulmonary fibrosis (IPF), and …

MMP-9基因位于染色体20q11.1~13.1，26~27kbp，具有13个外显子和9个内含子，属于基质金属蛋白酶（matrix metalloprotein,MMP ）家族。 主要功能是降解和重塑细胞外基质（extracellular matris）的动态平衡。

MMP-9 can cleave many extracellular matrix (ECM) proteins to regulate ECM remodeling. It can also cleave many plasma surface proteins to release them from the cell surface. MMP-9 has been widely found to relate to the pathology of cancers, including but not limited to invasion, metastasis and angiogenesis.

基质金属蛋白酶9 (MMP-9)，又名92kDaIV型胶原酶、92kDa明胶酶或者明胶酶B，是一类属于锌-金属蛋白酶家族的酶。 MMP-9参与正常生理过程 (如胚胎发育、繁殖、血管形成、骨骼发育、伤口愈细胞迁移、学习和记忆)和病理过程 (如关节炎、脑出血和肿瘤转移)的细胞外 ...

2019年2月25日 · MMP-9可作为哮喘气道重塑生物标志物，若能类似脑钠肽评估心力衰竭一样定性或定量评估哮喘，则对临床明确诊断、评估严重程度、制定个体化治疗方案、预测预后都将产生重大意义。
