Cleaves aggrecan, a cartilage proteoglycan, and may be involved in its turnover. May play an important role in the destruction of aggrecan in arthritic diseases. Cleaves aggrecan at the '392-Glu-|-Ala-393' site (By similarity). Glutamyl endopeptidase. Bonds cleaved include 370-Thr-Glu-Gly-Glu-|-Ala-Arg-Gly-Ser-377 in the interglobular domain of mammalian aggrecan. Binds 1 zinc ion per subunit. Interacts with SRPX2. In embryonic skeletal muscle, significantly increased levels between 13.5 dpc and 15.5 dpc with maximal expression observed at 15.5 dpc (PubMed:23233679). Decreased levels in postnatal skeletal muscle (PubMed:23233679). In myoblasts, up-regulated soon after induction of myoblast differentiation (PubMed:23233679). The spacer domain and the TSP type-1 domains are important for a tight interaction with the extracellular matrix. The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme. The precursor is cleaved by a furin endopeptidase. Glycosylated. Can be O-fucosylated by POFUT2 on a serine or a threonine residue found within the consensus sequence C1-X(2)-(S/T)-C2-G of the TSP type-1 repeat domains where C1 and C2 are the first and second cysteine residue of the repeat, respectively. Fucosylated repeats can then be further glycosylated by the addition of a beta-1,3-glucose residue by the glucosyltransferase, B3GALTL. Fucosylation mediates the efficient secretion of ADAMTS family members. Can also be C-glycosylated with one or two mannose molecules on tryptophan residues within the consensus sequence W-X-X-W of the TPRs, and N-glycosylated. These other glycosylations can also facilitate secretion (By similarity).
