72 kDa type IV collagenase also known as matrix metalloproteinase-2 (MMP-2) and gelatinase A is an enzyme that in humans is encoded by the MMP2 gene. Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Alternative Names: MMP 2, MMP-2 Proenzyme Protein, MMP2, MMP 2 Proenzyme Protein, MMP 2 protein, MMP-2, MMP-2 protein, Matrix Metalloproteinase 2 Protein
