Comments
  • FUNCTION: Important for the overall degradation of proteins in lysosomes. May be responsible for preparing the endometrium for blastocyst implantation.
  • CATALYTIC ACTIVITY: Specificity close to that of papain. As compared to cathepsin B, cathepsin L exhibits higher activity toward protein substrates, but has little activity on Z-Arg-Arg-NHMec, and no peptidyl-dipeptidase activity.
  • SUBUNIT: Dimer of a heavy and a light chain linked by disulfide bonds.
  • SUBCELLULAR LOCATION: Lysosome.
  • INDUCTION: By progesterone.
  • SIMILARITY: Belongs to the peptidase C1 family [view classification].
