|Other Names||Cystatin-D, Cystatin-5, CST5|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP8984c was selected from the Center region of human CST5. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Cysteine proteinase inhibitor that possibly plays a protective role against proteinases present in the oral cavity. The order of preference for inhibition is cathepsin S > cathepsin H > cathepsin L > cathepsin B.|
|Tissue Location||Expressed in submandibular and sublingual saliva but not in parotid saliva (at protein level). Expressed in parotid gland but not in seminal vesicle, prostate, epididymis, testis, ovary, placenta, thyroid, gastric corpus, small intestine, liver, or gall bladder tissue.|

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. CST5 may play a protective role against proteinases present in the oral cavity.
