About CTSK

Cytogenetic location: 1q21.3 Genomic coordinates (GRCh38): 1:150,796,208-150,808,260 (from NCBI)

This gene has 20 transcripts (splice variants), 240 orthologues, 12 paralogues and is associated with 3 phenotypes. Broad expression in gall bladder (RPKM 190.4), urinary bladder (RPKM 132.0) and 15 other tissues.

Summary

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. [provided by RefSeq, Apr 2013]
