PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a signal sequence
  • a propeptide domain
  • a reprolysin-type catalytic domain
  • a zinc catalytic domain
  • non-catalytic ancillary domains
  • a disintegrin domain (Dis)
  • a thrombospondin domain
  • a cysteine-rich domain (Cysr)
  • a spacer domain (Sp)
  • a second thrombospondin domain follows the spacer domain
  • one C terminal TSP-like module, that govern the specificity of the enzymes by modulating substrate binding
  • CysR and Sp domains greatly increased its aggrecanolytic activity
  • C-terminal domains affect the structure around the active site, favouring interaction with TIMP3
  • conjugated MetalloP

    HOMOLOGY
    interspecies homolog to murine Adamts5
    Homologene
    FAMILY
  • ADAMTS (a disintegrin and metalloproteinase with thrombospondin motif) protein family
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • cell surface adhesion protein cleaving the cartilage proteoglycan aggrecan, involved in the destruction of aggrecan in arthritic disease
  • may play a role in glioma cell invasion through the cleavage of brevican
  • major aggrecanase in cartilage metabolism and pathology
  • (aggrecanolytic activity of ADAMTS5 was much greater than ADAMTS4)
  • ADAMTS4 and ADAMTS5 not only play roles in the breakdown of cartilage extracellular matrix in osteoarthritis, but also mediate processing of matrilins in the secretory pathway
  • in the growth plate ADAMTS5, and not ADAMTS4, has a physiological function in the intracellular processing of matrilins and potentially of other extracellular matrix proteins
  • role of ADAMTS5 in tendon is to remove pericellular and interfibrillar aggrecan to maintain the molecular architecture responsible for normal tissue function
  • a function of ADAMTS5 in dermal fibroblasts is potentially to maintain optimal versican content and pericellular matrix volume by continually trimming versican in hyaluronan-versican aggregates

    INTERACTION
    DNA
    RNA
    small molecule metal binding,
  • Zn2+
  • protein
  • interaction with Syndecan-4 (controls the activation of ADAMTS5 through direct interaction with the protease and through regulating mitogen-activated protein kinase (MAPK)-dependent synthesis of MMP3)
  • LRP1 dictates physiological and pathological catabolism of aggrecan in cartilage and is a key modulator of the extracellular activity of ADAMTS5
  • RELA is a potent transcriptional activator of ADAMTS5 in chondrocytes during osteoarthritis development
  • ADAMTS4 and ADAMTS5 may destabilize the filamentous network in the extracellular matrix by cleaving MATN2 in both homo-oligomers and hetero-oligomers
  • role for SDC4 in mediating matrix degradation in both intervertebral discs and cartilage by controlling ADAMTS5 function and MMP3 expression
