MMP2(matrix metallopeptidase 2),癌症关联基因,基因ID:4313,该基因是基质金属蛋白酶(MMP)基因家族的成员,是锌依赖性酶,能够切割细胞外基质的成分和参与信号转导的分子。该基因编码的蛋白是一种胶原酶A,IV型胶原酶,在其催化位点包含三个纤维连接蛋白II型重复序列,允许变性的IV型和V型胶原和弹性蛋白结合。与大多数MMP家族成员不同,这种蛋白的活化可以发生在细胞膜上。这种酶可以通过蛋白酶在细胞外激活,也可以通过S-谷胱甘肽在细胞内激活,而不需要蛋白质水解去除原结构域。这种蛋白被认为参与多种途径,包括在神经系统、子宫内膜月经破裂、血管化调节和转移中的作用。该基因突变与温彻斯特综合征和结节性关节病骨溶解(NAO)综合征有关。选择性剪接导致编码不同亚型的多个转录变体。This gene is a member of the matrix metalloproteinase (MMP) gene family, that are zinc-dependent enzymes capable of cleaving components of the extracellular matrix and molecules involved in signal transduction. The protein encoded by this gene is a gelatinase A, type IV collagenase, that contains three fibronectin type II repeats in its catalytic site that allow binding of denatured type IV and V collagen and elastin. Unlike most MMP family members, activation of this protein can occur on the cell membrane. This enzyme can be activated extracellularly by proteases, or, intracellulary by its。
