CATB fulfills a number of functions:

cysteine-type endopeptidase activity – kininogen binding – peptidase activity – peptide binding – cysteine-type peptidase activity – endopeptidase activity – hydrolase activity – protein complex binding – protein binding

CATB is relevant to the following processes:

proteolysis – regulation of apoptosis – regulation of catalytic activity – response to wounding – negative regulation of cell death – autophagy – response to amine stimulus – response to ethanol – response to glucose stimulus – response to interleukin-4 – response to mechanical stimulus – response to organic cyclic substance – response to peptide hormone stimulus – response to protein stimulus – response to stress – skeletal muscle tissue development

Locations for CATB:

apical plasma membrane – external side of plasma membrane – extracellular region – intracellular – lysosome – melanosome – mitochondrion – soluble fraction – caveola – cell surface – cytoplasm – extracellular space – perinuclear region of cytoplasm – sarcolemma
