Matrix metalloproteinase enzyme (MMP)

Matrix metalloproteinases are a family of calcium-dependent, zinc-containing endopeptidase enzymes responsible for degrading various components of the extracellular matrix. These enzymes play critical roles in tissue remodeling, cell migration, angiogenesis, and inflammation. In pathological conditions, MMPs facilitate tumor invasion, metastasis, and can serve as both biomarkers and therapeutic targets, especially in cancer and inflammatory diseases. Due to their complex roles in normal physiology and disease, drug development efforts focus on producing selective inhibitors to avoid negative effects resulting from broad inhibition. MMPs are synthesized as inactive zymogens that require activation by proteolytic cleavage or other mechanisms.
