Matrix metalloproteinase 25 (MMP25), also known as membrane-type MMP 6 (MT6-MMP), is a member of the zinc-dependent endopeptidase family involved in extracellular matrix (ECM) remodeling and tissue homeostasis. Discovered in the late 1990s, MMP25 is distinguished by its unique structure, featuring a propeptide domain, catalytic domain, hinge region, and hemopexin-like domain. Unlike many soluble MMPs, it is anchored to the cell membrane via a glycosylphosphatidylinositol (GPI) linkage, enabling localized proteolytic activity. This membrane association allows MMP25 to participate in cell surface-mediated processes, including cell migration, immune response modulation, and cancer progression.
MMP25 is predominantly expressed in immune cells, particularly leukocytes, neutrophils, and monocytes, linking it to inflammatory and pathological conditions. It cleaves ECM components (e.g., collagen IV, gelatin) and processes cytokines, chemokines, and other MMPs, amplifying proteolytic cascades. Studies highlight its role in chronic inflammation, neurodegenerative diseases, and tumor metastasis, where it facilitates tumor cell invasion by degrading basement membranes and activating pro-invasive signaling pathways.
Recombinant MMP25 protein is produced using expression systems (e.g., E. coli, mammalian cells) to enable functional studies. Purification often involves affinity chromatography tags (His-tag, GST-tag) for high yield and specificity. Researchers use the recombinant protein to investigate substrate specificity, screen inhibitors for therapeutic development, and model MMP25-driven pathologies. Its enzymatic activity is typically assessed using fluorogenic substrates or zymography.
Despite progress, MMP25’s full pathophysiological roles remain understudied compared to other MMPs. Ongoing research focuses on its dual roles in immunity and cancer, aiming to clarify its potential as a biomarker or therapeutic target in diseases like multiple sclerosis, atherosclerosis, and metastatic cancers.
