Description
This gene encodes a member of the peptidase C1 family and preproprotein that is proteolytically processed to generate multiple protein products. These products include the cathepsin B light and heavy chains, which can dimerize to generate the double chain form of the enzyme. This enzyme is a lysosomal cysteine protease with both endopeptidase and exopeptidase activity that may play a role in protein turnover. Homozygous knockout mice for this gene exhibit reduced pancreatic damage following induced pancreatitis and reduced hepatocyte apoptosis in a model of liver injury. Pseudogenes of this gene have been identified in the genome. [provided by RefSeq, Aug 2015]
Enables cysteine-type endopeptidase activity. Involved in proteolysis involved in protein catabolic process; symbiont entry into host cell; and thyroid hormone generation. Acts upstream of or within decidualization. Located in external side of plasma membrane; extracellular space; and lysosome. Is expressed in several structures, including extraembryonic component; eye; limb interdigital region; long bone; and metanephros. Human ortholog(s) of this gene implicated in diabetes mellitus. Orthologous to human CTSB (cathepsin B).

3 Proteins

3.1 Protein Function

Thiol protease which is believed to participate in intracellular degradation and turnover of proteins (By similarity). Cleaves matrix extracellular phosphoglycoprotein MEPE (By similarity). Involved in the solubilization of cross-linked TG/thyroglobulin in the thyroid follicle lumen (PMID: 12782676). Has also been implicated in tumor invasion and metastasis (By similarity).
