abstract = {Tissue inhibitor of metalloproteinases 3 (TIMP-3) is a key
regulator of extracellular matrix turnover for its ability
to inhibit matrix metalloproteinases (MMPs), adamalysin-like
metalloproteinases (ADAMs) and ADAMs with thrombospondin
motifs (ADAMTSs). TIMP-3 is a secreted protein whose
extracellular levels are regulated by endocytosis via the
low-density-lipoprotein receptor-related protein-1 (LRP-1).
In this study we developed a molecule able to 'trap' TIMP-3
extracellularly, thereby increasing its tissue
bioavailability. LRP-1 contains four ligand-binding
clusters. In order to investigate the TIMP-3 binding site on
LRP-1, we generated soluble minireceptors (sLRPs) containing
the four distinct binding clusters or part of each cluster.
We used an array of biochemical methods to investigate the
binding of TIMP-3 to different sLRPs. We found that TIMP-3
binds to the ligand-binding cluster II of the receptor with
the highest affinity and a soluble minireceptor containing
the N-terminal half of cluster II specifically blocked
TIMP-3 internalization, without affecting the turnover of
metalloproteinases. Mass spectrometry-based secretome
analysis showed that this minireceptor, named T3TRAP,
selectively increased TIMP-3 levels in the extracellular
space and inhibited constitutive shedding of a number of
cell surface proteins. In conclusion, T3TRAP represents a
biological tool that can be used to modulate TIMP-3 levels
in the tissue and could be potentially developed as a
therapy for diseases characterized by a deficit of TIMP-3,
including arthritis.},
