The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 90 kDa. This antibody detects ADAMTS4 at ~68, ~53 and 30 kDa protein representing ADAMTS4 and its proteolytic fragments. Depending on the extent of C-terminal processing, several smaller bands may also be seen using this antibody.
FunctionCleaves aggrecan, a cartilage proteoglycan, and may be involved in its turnover. May play an important role in the destruction of aggrecan in arthritic diseases. Could also be a critical factor in the exacerbation of neurodegeneration in Alzheimer disease. Cleaves aggrecan at the '392-Glu- -Ala-393' site.
Tissue specificityExpressed in brain, lung and heart. Expressed at very low level in placenta and skeletal muscles.
DomainThe 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.
Post-translational modificationsThe precursor is cleaved by a furin endopeptidase.
