Recombinant Human Cystatin F/CST7 (C-6His)

Source: Human Cells. MW :15.58kD. Recombinant Human Cystatin F is produced by our Mammalian expression system and the target gene encoding Gly20-His145 is expressed with a 6His tag at the C-terminus. CST7 is a secreted protein and primarily expressed in peripheral blood cells and spleen.It is belongs to the cystatin family. The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens. The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secretions. This gene encodes a glycosylated cysteine protease inhibitor with a putative role in immune regulation through inhibition of a unique target in the hematopoietic system.
