| Description |
CST7 Human Recombinant produced in E. coli is a single polypeptide chain containing 132 amino acids (20-145) and having a molecular mass of 15.3kDa.CST7 is fused to a 7 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques. |
| Protein Background |
Cystatin 7 (CST7) is a glycosylated cysteine protease inhibitor with a putative role in immune regulation through inhibition of a unique target in the hematopoietic system. Cystatin-7 is comprised of multiple cystatin-like sequences. The superfamily is comprised of 3 inhibitory families: the type 1 cystatins (stefins), type 2 cystatins and the kininogens. Some members are active cysteine protease inhibitors, while others have lost or possibly never had this inhibitory activity. Type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in various human fluids and secretions. CST7 protein expression has been observed in numerous human cancer cell lines established from malignant tumors. |
