What cell makes MMPs?
MMPs are produced by many cell types, including lymphocytes and granulocytes, but in particular by activated macrophages (17).
What is the function of matrix metalloproteinases?
Matrix metalloproteinases (MMPs), also called matrixins, function in the extracellular environment of cells and degrade both matrix and non-matrix proteins.
How are MMPs activated?
The MMP activation by reactive oxygen is driven through preferential oxidation of the thiol–zinc interaction and autocatalytic cleavage, followed by enzyme inactivation with extended exposure by modification of amino acids critical for catalytic activity, as shown in vitro for MMP-7 [30].
What secretes matrix metalloproteinases?
Matrix metalloproteinases (MMPs) are zinc-dependent proteases whose physiological roles include control of leukocyte migration. Macrophages secrete a broad range of MMPs and represent a key source of MMPs in inflammatory lesions such as granulomas.
What is the function of TIMPs?
TIMPs have various biological activities including the modulation of cell proliferation, cell migration and invasion, anti-angiogenesis, anti- and pro-apoptosis and synaptic plasticity.
What is zinc metalloprotease?
A metalloproteinase, or metalloprotease, is any protease enzyme whose catalytic mechanism involves a metal. EDTA is a metal chelator that removes zinc, which is essential for activity. They are also inhibited by the chelator orthophenanthroline.
Where are matrix metalloproteinases?
The matrix metalloproteinases (MMPs) are a subfamily within the M10 family of endopeptidases of the metzincin clan (M10A; Rawlings et al., 2012) They are found in lower eukaryotes and in plants but diversified substantially during the evolution of the vertebrates (Fanjul-Fernandez et al., 2010).
Are MMPs enzymes?
The main group of enzymes responsible for the collagen and other protein degradation in extracellular matrix (ECM) are matrix metalloproteinases (MMPs). MMPs and their inhibitors are extensively examined as potential anticancer drugs. MMP inhibitors can be divided into two main groups: synthetic and natural inhibitors.
