Product Science Overview
Matrix Metalloproteinase-9 (MMP-9), also known as Gelatinase B, is a member of the matrix metalloproteinase (MMP) family. These enzymes are zinc and calcium-dependent endopeptidases that play a crucial role in the degradation of the extracellular matrix (ECM) components. The human recombinant form of MMP-9, expressed in Sf9 insect cells, is widely used in research to study its biochemical properties and physiological functions.
MMP-9 is initially synthesized as an inactive zymogen, known as proMMP-9, with a molecular weight of approximately 92 kDa . Activation of proMMP-9 involves the cleavage of its propeptide domain, resulting in the active enzyme with a molecular weight of around 82 kDa . The active form of MMP-9 contains a catalytic domain that is responsible for its enzymatic activity.
MMP-9 plays a significant role in various physiological processes, including:
- Extracellular Matrix Remodeling: MMP-9 degrades various components of the ECM, such as collagen and gelatin, which is essential for tissue remodeling and repair .
- Angiogenesis: MMP-9 regulates the formation of new blood vessels by modulating the ECM and releasing angiogenic factors .
- Wound Healing: MMP-9 is involved in the breakdown of ECM components during the wound healing process, facilitating cell migration and tissue regeneration .
While MMP-9 is vital for normal physiological functions, its dysregulation is associated with several pathological conditions:
- Cancer: Overexpression of MMP-9 is linked to tumor invasion and metastasis, as it degrades the ECM barriers that confine tumor cells .
- Arthritis: MMP-9 contributes to the degradation of cartilage in inflammatory joint diseases such as rheumatoid arthritis .
- Cardiovascular Diseases: Elevated levels of MMP-9 are implicated in the remodeling of blood vessels and the progression of atherosclerosis .
