While binding of TIMP-2 to MMP-12 hinders membrane interactions beside the active site, TIMP-2-inhibited MMP-12 binds vesicles and cells, suggesting compensatory rotation of its membrane approaches. MMP-12 binds plasma membranes and is internalized to hydrophobic perinuclear features, the nuclear membrane and inside the nucleus within minutes. Both interfaces mediate MMP-12 association with vesicles and cell membranes. The distal membrane interface comprises loops on the other side of the catalytic cleft. Loops project from the β-sheet interface to contact the phospholipid bilayer with basic and hydrophobic residues. Opposing sides of the catalytic domain engage spin-labelled membrane mimics. Here we demonstrate the binding of MMP-12 directly to bilayers and cellular membranes using paramagnetic NMR and fluorescence. Some soluble MMPs are inexplicably active near cell surfaces. Matrix metalloproteinases (MMPs) regulate tissue remodelling, inflammation and disease progression.
