<http://identifiers.org/uniprot/P31431> <http://www.biopax.org/release/biopax-level3.owl#comment> "FUNCTION: Cell surface proteoglycan that bears heparan sulfate. SUBUNIT: Homodimer. Interacts (via its cytoplasmic domain) with GIPC (via its PDZ domain). Interacts (via its cytoplasmic domain) with NUDT16L1 (By similarity). Interacts with CDCP1 and SDCBP. SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein. Secreted. Note=Shedding of the ectodomain produces a soluble form (By similarity). TISSUE SPECIFICITY: Expressed in epithelial and fibroblastic cells. PTM: Shedding is enhanced by a number of factors such as heparanase, thrombin or EGF. Also by stress and wound healing. PMA-mediated shedding is inhibited by TIMP3. SIMILARITY: Belongs to the syndecan proteoglycan family. GENE SYNONYMS:SDC4.
