motifs/domains
  • domains similar to hemorrhagic snake venom proteins (HSVP) with a prodomain
  • a Zn-binding site metalloproteinase
  • a disintegrin-like domain
  • a cysteine-rich domain
  • an EGF-like repeat
  • a transmembrane domain
  • a proline-rich SH3 cytoplasmic tail suggesting that it interacts with other cytoplasmic proteins
  • conjugated GlycoP , MetalloP
    HOMOLOGY
    interspecies homolog to murine Adam8
    Homologene
    FAMILY
  • peptidase family M12B
  • ADAM (a disintegrin and metalloprotease domain) family
  • CATEGORY adhesion , antigen

    basic FUNCTION
  • playing an important role in osteoclast formation and differentiation
  • involved in cell-cell and cell-matrix interactions
  • may be contributing to ectodomain shedding of CD23
  • involved in ectodomain shedding of membrane proteins and is linked to inflammation and neurodegeneration
  • may play a significant role in tumor invasion that may be detrimental to patients survival
  • stimulates osteoclast differentiation
  • may have a potential relevant role in the function of neutrophils during inflammatory response
  • stimulates osteoclast (OCL) formation
  • modulates the expression and function of SELPLG
  • is the primary protease for the alpha-cleavage of PRNP that appears self-regulated through ADAM8 in muscle
  • mediates cell adhesion and shedding of ligands, receptors and extracellular matrix components
  • mediates an enhanced invasiveness of neutrophils into injured muscle fibers by the removal of their adhesiveness to blood vessels after infiltration into interstitial tissue
  • role in pancreatic cancer signalling
  • could promote the proliferation of normal hepatocytes and render hepatoma carcinoma cells more resistant to apoptosis to play important roles during the progression of hepatocellular carcinoma
  • CELLULAR PROCESS protein, degradation

  • Zn2+
  • protein
  • CD23
  • is both associated with SELPLG through the ezrin–radixin–moesin actin-binding proteins and able to cause the proteolytic cleavage of this adhesion receptor
  • is the primary protease responsible for the alpha-cleavage of PRNP in muscle cells
  • ADAM8 can perform alpha-cleavage of PRNP and PRNP can regulate ADAM8 expression

    ANIMAL & CELL MODELS
  • skeletal muscle of dystrophin-null mice, an animal model for Duchenne Muscular Dystrophy, deteriorates by the lack of Adam8, which is characterized by increased area of muscle degeneration and increased number of necrotic and calcified muscle fibers
