Summary: Predicted to enable several functions, including collagen binding activity; cysteine-type endopeptidase activator activity involved in apoptotic process; and fibronectin binding activity. Involved in several processes, including bone resorption; cellular response to transforming growth factor beta stimulus; and cellular response to zinc ion starvation. Located in extracellular space. Biomarker of intracranial aneurysm and otitis media. Human ortholog(s) of this gene implicated in pycnodysostosis. Orthologous to human CTSK (cathepsin K).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
