Gene Information

human ... CTSK(1513)

General description

The protein encoded by this gene is a lysosomal cysteine proteinase involved in bone remodeling and resorption. This protein, which is a member of the peptidase C1 protein family, is predominantly expressed in osteoclasts. However, the encoded protein is also expressed in a significant fraction of human breast cancers, where it could contribute to tumor invasiveness. Mutations in this gene are the cause of pycnodysostosis, an autosomal recessive disease characterized by osteosclerosis and short stature. This gene may be subject to RNA editing.

Biochem/physiol Actions

Cathepsin K has a role in bone resorption and remodeling. It has a triple helical collagen hydrolase activity. Mutations in the gene encoding this protein have been linked to pycnodysostosis.
