Cathepsin S is also known as CTSS, which is a member of the peptidase C1 family.
Cathepsin S is a lysosomal cysteine protease that may participate in the degradation of antigenic proteins to peptides for presentation on MHC class II molecules.
Cathepsin S can function as an elastase over a broad pH range in alveolar macrophages.
The catalytic activity of cathepsin S is similar to cathepsin L, but with much less activity on Z-Phe-Arg-|-NHMec, and more activity on the Z-Val-Val-Arg-|-Xaa compound.
特徴
This protein carries a polyhistidine tag at the C-terminus.
This protein contains an Activation peptide(17 Q-114 I), and will be partially processed into Pro form with calculated MW of 39 kDa and mature form with calculated MW of 28 kDa under reducing (R) condition.
