Summary
Protein Function
Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Has also been implicated in tumor invasion and metastasis. (From Uniprot)
Cathepsin B (CatB) is an enzymatic protein belonging to the peptidase (or protease) families. In humans, it is coded by the CTSB gene. The protein encoded by this gene is a lysosomal cysteine protease composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. It is a member of the peptidase C1 family. At least five transcript variants encoding the same protein have been found for this gene. (From Wikipedia)
Cys Function & Property
Cys108 is one of the active sites of Cathepsin B, which is very close to His278 and Asn298 in space. These three residues formed a typical catalytic triad motif.
- Hydrophobic property:
- SASA：
- Cys108: 4.025 A^2
