Source:
Type:
CTSB — Cathepsin B

Primary role: Lysosomal cysteine protease; executor of late-stage autophagic flux and mediator of lysosome-dependent cell death.

Cancer relevance:
CTSB is frequently overexpressed and mislocalized in cancer. In intact lysosomes, it enables productive autophagic flux by degrading autophagic cargo. Upon lysosomal membrane permeabilization (LMP), CTSB is released into the cytosol where it activates apoptotic signaling (including caspase-dependent and independent pathways). Extracellular CTSB promotes ECM degradation, invasion, and metastasis.

Net effect in established cancer:
Context-dependent, but predominantly pro-tumor via invasion and survival; pro-death when lysosomal integrity is lost.
