Background | The cystatin superfamily members are important natural cysteine protease inhibitors present in a wide variety of organisms and are divided into three classes. Cystatin F, also known as leukocystatin and CMAP (Cystatin-like Metastasis-Associated Protein), is a type 2 cystatin and its expression is limited to hematopoietic cells, with the highest expression levels being observed in monocytes, dendritic cells, and certain types of T-cells. Furthermore, cystatin F mRNA becomes up-regulated during dendritic cell maturation, and thus suggests a specific role of cystatin F in immune regulation. Cystatin F is produced as a dimer, an inactive cathepsin inhibitor which is activated by chemical reduction. In addition, Cystatin F and its homologues have been observed expressing in various human cancer cell lines established from malignant tumors, and thus indicates a new diagnosis and prevention approach of certain human carcinomas metastasis. |
Description | The mature form of the human Cystatin F (NP_003641.3) (Met 1-His 145) with five amino acids (DDDDK) at the C-terminus was expressed and purified. |
Source | HEK293 |
Predicted N Terminal | Gly 20 |
AA Sequence | Met 1-His 145 |
Molecular Weight | The recombinant human Cystatin F consists of 132 a.a. and predicts a molecular mass of 15.2 kDa. As a result of glycosylation, the apparent molecular mass of rhCystatin F is approximately 25 kDa in SDS-PAGE. |
Purity | >95% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | Please contact us for detailed information |
