    basic FUNCTION
  • having metalloendopeptidase inhibitor activity
  • may be participaing in diverse steps of neurogenesis and inhibiting the processing of pro-matrix metalloproteinase 2 (MMP-2) by MT1-MMP and MT3-MMP
  • suppressing membrane-type 1 matrix metalloproteinase (MMP)-mediated MMP-2 activation and tumor invasion
