Overview
Product name Active Recombinant Human Cystatin-D/CST5 Protein Catalog No. RP01035 Description Active Recombinant Human Cystatin-D/CST5 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gly21-Val142) of human Cystatin D (Accession #NP_001891.2) fused with a 6×His tag at the C-terminus. Bio-Activity Measured by its ability to inhibit papain cleavage of a fluorogenic peptide substrate Z-FR-AM. The IC50 value is <18 nM. Purity > 90% by SDS-PAGE. Endotoxin < 0.1 EU/μg of the protein by LAL method. Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. Species Human Background
The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Cystatins are natural inhibitors of papain-like (family C1) and legumain-related (family C13) cysteine peptidases. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens. As a member of type 2 cystatin, cystatin D is a single-domain protein and also has cysteine residues that form disulfide bridges. The functions of Cystatin D are largely unknown. However, Cystatin D has been shown to inhibit coronavirus replication at its physiological concentration (0.12_x005fProduct information
