    motifs/domains
  • a very short proregion
  • a three residue insertion between Gly22 and Cys31
  • a highly conserved region of the catalytic triad,
  • a second insertion homologous to the occluding loop in CTSB
  • an RGD motif located in a highly exposed region of the propeptide, which may allow binding of the proenzyme to RGD-recognizing integrins
    • isoforms Precursor

    basic FUNCTION
  • placental cysteine proteinase, with putative exopeptidase activity
  • may be involved in tumorigenesis
  • has a restricted catalytic specificity
  • extracellular function of cathepsin Z may include binding to integrins thereby modulating the attachment of migrating cells to extracellular matrix components
  • with BLMH, are both cysteine proteases of a papain-like structure, and mediate N-terminal proteolysis and toxicity of mutant huntingtin
  • cysteine carboxypeptidase, that is involved in the regulation of T cell migration by interaction with ITGB2
  • potential role of cathepsin Z in bypassing cellular senescence
    • CELLULAR PROCESS protein, degradation
