Product details:
MMP2 Inhibitor Screening Assay Kit (Colorimetric) (ab139446) is a complete assay system designed to screen MMP2 inhibitors using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC
). The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5'-dithiobis(2-nitrobenzoic acid), Ellman's reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (ε=13,600 M
at pH 6.0 and above). The assays are performed in a convenient 96-well microplate format.
This kit is useful to screen inhibitors of MMP2, a potential therapeutic target. The MMP inhibitor NNGH is also included as a prototypic control inhibitor.
Thiol inhibitors should not be used with this kit, as they may interfere with the colorimetric assay.

The MMP-2 protein also known as matrix metalloproteinase-2 or gelatinase A is an enzyme involved in the breakdown of extracellular matrix components. It plays a critical role in tissue remodeling and cell migration. Comprised of a molecular weight of approximately 72 kDa this metalloproteinase is secreted as an inactive proenzyme that requires activation. MMP2 is expressed in various tissues including the brain heart and blood vessels where it contributes to normal physiological processes and pathological conditions.
Biological function summary
Matrix metalloproteinase-2 is mainly involved in the degradation of type IV and V collagens gelatin and fibronectin. As part of the metalloproteinase family it works alongside other MMPs to maintain tissue homeostasis and repair. MMP-2 forms part of a complex network that ensures the timely degradation of matrix components balancing synthesis and breakdown. It remains regulated by tissue inhibitors of metalloproteinases (TIMPs) preventing excessive degradation that could lead to tissue damage.
Pathways
MMP-2 plays a significant role within the extracellular matrix (ECM) remodeling and angiogenesis pathways. It interacts with various proteins including integrins and TIMP-2 to modulate cellular behaviors such as migration and invasion. MMP-2 contributes to processes like wound healing and embryonic development through its involvement in ECM degradation and new tissue formation.
Matrix metalloproteinase-2 is linked to cancer progression and cardiovascular diseases. In cancer abnormal MMP-2 activity facilitates tumor invasion and metastasis by breaking down matrix barriers. Increased MMP-2 expression associates with poor prognosis in cancers like breast and prostate. In cardiovascular diseases such as atherosclerosis it contributes to plaque destabilization and vascular remodeling. The imbalance in MMP-2 activity and its regulation by proteins like TIMP-1 are involved in the pathology of these disorders.
