ADAMTS4 Fluorogenic Assay Kit

• Background:

  ADAMTS4 (A disintegrin and metalloproteinase with thrombospondin motifs 4), also known as aggrecanase-1, is a member of the ADAMTS proteinase family but lacks the C-terminal domain and it is the only member of the family that does not undergo glycosylation. Its TSR (thrombospondin type 1 motif) is essential for its function, by binding to the extracellular matrix proteins. ADAMTS4 can be found in several tissues, such as the ovary, retina, breast, brain and others, and it is involved in cleaving CSPGs (chondroitin sulfate hyaluronan-binding proteoglycans), such as aggrecan, neurocan and versican. It can be inhibited by TIMP3 (metalloproteinase inhibitor 3), and dysfunction can result in osteoarthritis. In addition, it can be a biomarker for adult cardiac injury, as it becomes expressed under those conditions and contributes to fibrosis. In a rat model, inhibition of ADAMST4 resulted in improved cardiac responses and lower accumulation of collagen. The development of ADAMST4 inhibitors can thus open new therapeutic avenues in cardiology.

• Description:

  The ADAMTS4 Fluorogenic Assay Kit is designed to measure ADAMTS4 (A disintegrin and a metalloproteinase with thrombospondin motifs 4) protease activity for screening and profiling applications. The assay kit comes in a convenient 96-well format, with enough recombinant ADAMTS4, fluorogenic substrate, and assay buffer for 100 enzyme reactionsFigure 1: Illustration of the mechanism behind the ADAMST4 Fluorogenic Assay Kit.ADAMTS4 is incubated with a fluorogenic substrate which is an internally quenched fluorogenic substrate. Proteolysis releases the highly fluorescent Mca from the quencher. Fluorescence intensity increases proportionally to the activity of the protease.Need us to run inhibitor screens or profile your compounds against ADAMTS4? Check out ourProtease Screening Services.

• Contraindications:

  The final concentration of DMSO in the assay should not exceed 1%.Compounds that are fluorescent may interfere with the results, depending on their spectral excitation and emission properties.It is recommended that the compound alone is tested to determine any potential interference of the compound with the assay results.The presence of strong acids or bases, ionic detergents and high salt should be avoided.
