Product details:
Abcam's MMP3 Inhibitor Screening Assay Kit (Colorimetric) (ab139439) is a complete assay system designed to screen MMP3 inhibitors using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC
H5). 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 MMP3, 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.

MMP3 also known as stromelysin-1 is a member of the matrix metalloproteinase (MMP) family. These proteins are zinc-dependent endopeptidases. MMP3 specifically has a molecular weight of approximately 54 kDa and is responsible for degrading extracellular matrix components such as collagen fibronectin and laminin. MMP3 is expressed in various tissues including fibroblasts chondrocytes and endothelial cells. It plays a significant role in tissue remodeling wound healing and potentially aids in the breakdown of cellular matrices.
Biological function summary
MMP3 contributes to multiple physiological and pathological processes. It supports the remodeling of connective tissues and assists in normal developmental processes. MMP3 can work as part of a complex with other MMP proteins which can enhance or inhibit its activity. The balance of MMPs including MMP3 regulates the extracellular matrix turnover and is important for maintaining tissue homeostasis.
Pathways
MMP3 participates in pathways involved in tissue remodeling and inflammatory responses. It is part of cellular pathways regulated by cytokines like interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha). These pathways link MMP3 to other proteins such as MMP1 and MMP9 which perform overlapping and distinct roles in matrix degradation during inflammation and tissue repair.
MMP3 is implicated in conditions like arthritis and cardiovascular diseases. MMP3 contributes to cartilage degradation in rheumatoid arthritis and is associated with the breakdown of vascular structures in atherosclerosis. Proteins like MMP9 and MMP13 often interact with MMP3 in these pathological conditions forming a network that exacerbates tissue damage and disease progression.
