Biological function summary

Cathepsin O participates in protein degradation and turnover processes. It function as a protease that breaks peptide bonds aiding in the recycling of cellular components. Though not part of a well-defined complex it cooperates with other proteases to maintain the balance of intracellular proteins. Its activity has implications for cellular homeostasis and likely immune responses due to its expression in immune-related tissues like the thymus.

Pathways

Cathepsin O contributes to intracellular protein degradation pathways particularly involving proteolysis. It has connections with lysosomal degradation pathways and the ubiquitin-proteasome system. Cathepsin L and Cathepsin B operate similarly within these pathways suggesting that Cathepsin O may work in concert or compensate for deficiencies in these enzymes. This ties Cathepsin O to critical cellular processes maintaining protein quality control and regulating cell structure components.
