Regulation of matrix metalloproteinase-2 (MMP-2) activity by phosphorylation.
The regulation of matrix metalloproteinases (MMP) has been studied extensively due to the fundamental roles these zinc-endopeptidases play in diverse physiological and pathological processes. However, phosphorylation has not previously been considered as a potential modulator of MMP activity. The ubiquitously expressed MMP-2 contains 29 potential phosphorylation sites. Mass spectrometry reveals...
متن کاملStructural basis for matrix metalloproteinase-2 (MMP-2)-selective inhibitory action of β-amyloid precursor protein-derived inhibitor.
Unlike other synthetic or physiological inhibitors for matrix metalloproteinases (MMPs), the β-amyloid precursor protein-derived inhibitory peptide (APP-IP) having an ISYGNDALMP sequence has a high selectivity toward MMP-2. Our previous study identified amino acid residues of MMP-2 essential for its selective inhibition by APP-IP and demonstrated that the N to C direction of the decapeptide inh...
متن کاملRegulation of matrix metalloproteinase (MMP) gene expression by protein kinases.
Matrix metalloproteinases (MMPs) are a family of structurally and functionally related zinc-containing endopeptidases that are capable of degrading almost all of the components of the extracellular matrix (ECM). Under physiological and pathological conditions, the MMPs play a significant role in the efficient tissue turnover and remodeling. Specific MMPs are responsible for the matrix degradati...
متن کاملRegulation of endothelial matrix metalloproteinase-2 by hypoxia/reoxygenation.
Among the consequences resulting from the exposure of endothelial cells (ECs) to ischemia/reperfusion is angiogenesis, involving degradation of vascular basement membrane and extracellular matrix. Matrix metalloproteinase (MMP)-2, a member of the MMP family, partakes in this process. MMP-2, secreted as a proenzyme, undergoes activation through interaction with membrane type (MT)1-MMP and the en...
متن کاملNon-Fibrillar Oligomeric Amyloid-β within Synapses.
Alzheimer's disease (AD) is characterized by memory loss, insidious cognitive decline, profound neurodegeneration, and the extracellular accumulation of amyloid-β (Aβ) peptide in senile plaques and intracellular accumulation of tau in neurofibrillary tangles. Loss and dysfunction of synapses are believed to underlie the devastating cognitive decline in AD. A large amount of evidence suggests th...
