Matrix metalloproteinases (MMPs) are a family of over 25 secreted and cell surface enzymes that regulate various biological processes by degrading extracellular matrix (ECM) proteins and other pericellular substrates. They influence development, homeostasis, and disease by modulating cell behavior through their enzymatic activities. MMPs are tightly regulated at multiple levels, including transcription, post-transcriptional processing, secretion, activation, inhibition, and localization. They are involved in numerous physiological and pathological processes, such as embryonic development, tissue morphogenesis, wound repair, inflammatory diseases, and cancer. Recent advances have elucidated the structure, function, and regulation of MMPs, revealing their complex roles in biological systems. MMPs are regulated by various factors, including transcriptional regulators, endogenous activators and inhibitors, and cell surface localization. They are also involved in the regulation of other proteins, such as tissue inhibitors of metalloproteinases (TIMPs), which inhibit MMP activity. The regulation of MMPs is essential for maintaining proper cellular function and preventing disease. MMPs are involved in the degradation of ECM components, which is crucial for cell migration, invasion, and tissue remodeling. The regulation of MMPs is complex, involving multiple signaling pathways and interactions with other proteins. The study of MMPs has provided important insights into their roles in health and disease, and their regulation is a key area of research in understanding the mechanisms of various biological processes.Matrix metalloproteinases (MMPs) are a family of over 25 secreted and cell surface enzymes that regulate various biological processes by degrading extracellular matrix (ECM) proteins and other pericellular substrates.
