|Product Overview :
||Recombinant Human cathepsin F, CD33 signal peptide(1-16aa) + cathepsin S (a-a 20-end), with C-terminal His tag expressed inFreeStyle 293-F cells. MW= 53 kDa.
||Cathepsins are papain family cysteine proteinases that represent a major component of the lysosomal proteolytic system. Cathepsins generally contain a signal sequence, followed by a propeptide and then a catalytically active mature region. The very long (251 amino acid residues) proregion of the cathepsin F precursor contains a C-terminal domain similar to the pro-segment of cathepsin L-like enzymes, a 50-residue flexible linker peptide, and an N-terminal domain predicted to adopt a cystatin-like fold. The cathepsin F proregion is unique within the papain family cysteine proteases in that it contains this additional N-terminal segment predicted to share structural similarities with cysteine protease inhibitors of the cystatin superfamily. This cystatin-like domain contains some of the elements known to be important for inhibitory activity. CTSF encodes a predicted protein of 484 amino acids which contains a 19 residue signal peptide.
||FreeStyle 293-F cells.
||Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
