High impact information on CTSL

  • This finding in turn indicated that the protease for which MAG was a substrate had cathepsin L-like activity [1].
  • Cathepsin L-like activity in myelin was confirmed by peptidolysis experiments using known cathepsin L substrates [1].
  • 0. Cathepsin S was found to hydrolyse proteins at a similar rate to cathepsin L below pH 7 [2].
  • We show that proBac7 is a monocyte-selective chemoattractant, potentially contributing to the recruitment of these cells to infection sites, whereas proBac5 efficiently inhibits the in vitro activity of cathepsin L, a cysteine proteinase thought to contribute to tissue injury in inflammation [3].
  • The results strongly suggest the involvement of cathepsin B- and cathepsin L-like proteinases in the histolysis of the silk gland during metamorphosis [4].
 

Biological context of CTSL

  • N-terminal amino acid sequence confirms that cathepsin L and cathepsin S are different enzymes [5].
  • Based on pH profiles of activity, inhibition studies using diethylpyrocarbonate and the diazomethylketone Z-phe-ala-CHN2, and characterising the substrate specificity of the enzymes using fluorogenic peptide substrates we have shown that the 60-90-kDa proteinases are cathepsin L-like proteinases [6].
  • Although to a varying extent, P1, P2 and P3 inhibited papain, cathepsin B and cathepsin L. Analysis of the peptide mixtures of these inhibitors by RP-HPLC after hydrolysis with CNBr or aspartly endoproteinase N together with their amino acid composition revealed that P1, P2 and P3 cysteine proteinase inhibitors are isoforms of the same protein [7].
  • Antibody responses to the 28-30 kDa proteins were not detected in groups B-D until 3 weeks later than those observed in group A. Antibody responses to Fasciola hepatica cathepsin L proteases, which are known to induce protection, were monophasic, of the IgG1 isotype only and were not observed prior to secondary challenge in any of the four groups [8].
 

Anatomical context of CTSL

 

Associations of CTSL with chemical compounds

  • The appearance of higher molecular-sized components in the cathepsin L clots suggests that polymerisation involves the formation of molecular interactions that are resistant to boiling in mercaptoethanol and SDS [12].
  • Also, PTP does not exhibit dipeptidycarboxylpeptidase activity, a property of cathepsin B; PTP demonstrates no elastinolytic activity, a characteristic of cathepsin L. Importantly, the sensitivity of PTP to active-site-directed peptide diazomethane inhibitors and E-64c differs from that of cathepsins B, L, and H [13].
  • Both were rapidly inhibited by low concentrations of E-64 or leupeptin, but were unaffected by cathepsin-L-specific inhibitor Z-Phe-Phe-CHN2 [14].
