PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a signal sequence
  • a propeptide domain
  • a reprolysin-type catalytic domain
  • a zinc catalytic domain
  • non-catalytic ancillary domains, including a disintegrin domain (Dis)
  • a thrombospondin domain
  • a cysteine-rich domain (Cysr)
  • a spacer domain (Sp) without cysteine residues
  • a C- terminal TSP-like module implicated in aggrecanolytic activity, and governing the specificity of the enzymes by modulating substrate binding, and affect the structure around the active site, favouring interaction with TIMP3
  • conjugated MetalloP
    isoforms Precursor pro-form of ADAMTS-4 is not catalytically active and only a limited number of mechanisms mediate its N-terminal activation
    HOMOLOGY
    interspecies homolog to murine secretory protein
    Homologene
    FAMILY
  • ADAMTS (a disintegrin and metalloproteinase with thrombospondin motif) protein family
  • CATEGORY adhesion , enzyme
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • degrading the chondroitine sulfate proteoglycan (brevican)
  • playing a pivotal role in inflammatory joint disease, and in cartilage aggrecan degradation
  • epigenetically regulated and plays a role in aggrecan degradation in osteoarthritis
  • 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
  • proteinase thought to be involved in processes ranging from cartilage metabolism to ovarian follicle development
  • ADAMTS1 and ADAMTS4 play redundant and essential roles in perinatal kidney development
  • CELLULAR PROCESS protein, degradation

  • Zn2+
  • protein
  • aggrecan (binding by TPS1motif) for cleavage of aggrecan
  • interacting with adaptor proteins and RAS, that synergistically regulate IL1-induced ADAMTS4 expression in chondrocytes (
  • ADAMTS4 cleaves RELN in an isoform-specific manner
