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: 102 kDa. This antibody detects a major band at ~68 kDa protein representing ADAMTS5 from porcine cartilage extract. On human recombinant ADAMTS5 this antibody detects a major band at ~85 kDa. 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. May play a role in proteolytic processing mostly during the peri-implantation period.
Tissue specificityExpressed at low level in placenta primarily but also detected in heart and brain, cervix, uterus, bladder, esophagus, rib cartilage, chondroblastoma, fibrous tissue and a joint capsule from an arthritic patient.
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.
