CST11 Recombinant Protein

Source : E.coli. CST11 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 101 amino acids (26-103 a.a.) and having a molecular mass of 11.8kDa.CST11 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Cystatin 11 (CST11) is a member of the Cystatin family. The Cystatin superfamily is comprised of proteins with multiple cystatin-like sequences. Several family members are active cysteine protease inhibitors, other family members have lost or perhaps never developed this inhibitory activity. The Cystatin superfamily consists of three inhibitory families, 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. The majority of the type 2 cystatin genes and pseudogenes are contained in the cystatin locus on chromosome 20. CST11 is located in the cystatin locus and encodes an epididymal-specific protein whose specific function has not been verified yet.
