    basic FUNCTION
  • putatively involved in sperm maturation
  • may be playing a role in the interaction of lymphocytes with ITGA4B1-expressing leukocytes
  • playing a role in cell proliferation and progression of the lung carcinomas
  • may function as positive regulator of growth and differentiation of dental papilla mesenchymal cells and act as an important molecule mediating reciprocal epithelial-mesenchymal signaling during tooth organ development
  • involved in cell proliferation through enhanced bioavailability of IGFI released from the IGF1/IGFBP3 complex by selective IGFBP3 cleavage in breast carcinomas
  • degrading proteoglycans and may be involved in cartilage degradation in osteoarthritis
  • may promote angiogenesis in the breast carcinoma tissues by releasing vascular endothelial growth factor165 (VEGF165) after digestion of CTGF in the CTGF/VEGF165 complex
  • CELLULAR PROCESS cell life, differentiation
    protein, degradation
    a component
    small molecule metal binding,
  • Zn2+
  • protein
  • ligand for ITGA4B1
  • interact with integrins and is involved in the digestion of IGFBP3 through release of IGF1, a potent inducer of cell proliferation
  • interacting with SELPLG (ADAM28 promotes SELPLG/P-selectin-mediated leukocyte rolling adhesion to endothelial cells and subsequent infiltration into tissue spaces through interaction with SELPLG on leukocytes under inflammatory conditions)
  • also involved in activation of EGFR, MAPK1, MAPK3 and release of CD44
  • CTGF is a novel substrate of ADAM28
