    basic FUNCTION
  • trypsin inhibitor, may be involved in acute phase reactions
  • contributing to extracellular matrix stability by covalent linkage to hyaluronan (Hamm 2008)
  • anti-inflammatory protein, extensively proteolytically processed within the proline-rich region (its fragmentation patterns were closely associated with different disease conditions)(Song 2006)
