    PROTEIN
    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • cytoplasmic domain binding to RAB5A, a small GTPase that regulates intracellular trafficking and signaling events, and this interaction controls the onset of SDC1 shedding (Hayashida 2008)
  • a transmembrane domain having a regulatory function in controlling focal adhesion disassembly, which in turn controls cell migration speed

  • translocates into the nucleus and hampers tumor cell proliferation
  • basic FUNCTION
  • cell surface proteoglycan bearing both heparan sulfate and chondroitin sulfate and linking the cytoskeleton
  • to the interstitial matrix
  • involved in cell-cell adhesion, organization of cell-matrix adhesion, and regulation of growth factor signaling
  • playing an essential role in maintaining intestinal epithelial barrier function
  • physiological binding partner of TIAM1 and the PDZ domain has a function in cell-matrix adhesion and cell migration
  • regulates mesenchymal tumor cell adhesion and migration, and its different domains have differential effects
  • is a regulator of focal adhesion disassembly in migrating lung epithelial cells
  • cell surface proteoglycan that can organize co-receptors into a multimeric complex to transduce intracellular signals
  • in the germinal niche is a key regulator of the maintenance and proliferation of neural progenitor cells (NPCs) during cortical neurogenesis
  • promotes vascular smooth muscle cells (vSMCs) differentiation and quiescence
  • modulates the motility and resolution responses of macrophages
  • role of the syndecan (SDC1) heparan sulphate proteoglycans, the small intracellular adaptor SDCBP and associated regulators in the biogenesis and loading of exosomes with cargo
  • may modulate fibronectin fibrillogenesis and/or alter cell morphology during ECM production
  • soluble (shed) form of SDC1 has paracrine and autocrine functions and is normally produced in a regulated fashion

    protein
  • WNT
  • SDC1 and CASPR4, are potential TIAM1 PDZ domain binding proteins
  • SDC1 restrains migration in lung epithelium by activating RAP1A to slow focal adhesion disassembly
  • tyrosine phosphorylation of SDC1 triggers the robust recruitment of cortactin, which we found to be an essential mediator of efficient actin-dependent endocytosis
  • alternative binding of IL34 to chondroitin sulphates and SDC1 at the cell surface that modulates CSF1R activation
  • HPSE stimulates the exosomal secretion of SDCBP, SDC1 and certain other exosomal cargo, such as CD63, in a concentration-dependent manner
  • on epithelial tumor cells promotes MIF binding and MIF-mediated cell migration
  • cell & other

    ANIMAL & CELL MODELS
  • Sdc1 -/- mice (Alexander (00))
  • Sdc1(-/-) mice are able to synthesize and maintain a hydrodynamically relevant glycocalyx, which indicates that syndecan-1 is not an essential anchoring protein for the glycocalyx
