Általános leírás
HumanKine human Cystatin C is expressed as a non-glycosylated monomer in human HEK 293 cells. Cystatin C belongs to the cystatin superfamily. Two isoforms (pI = 7.8, 9.2) of native Cystatin C are found in human urine differentiated by the elimination of small basic peptides or amino acids from the N-terminal end of the protein. This protein is coded by a housekeeping gene, CST3 located on human chromosome 20p11.21 and is generated by nucleated cells.
Alkalmazás
Cystatin C human has been used as a standard in western blot assay. It has also been used to study its effect on the endopeptidase activity of activated Trichobilharzia regenti isoform of cathepsin B1 peptidase (TrCB1).
Biokémiai/fiziológiai hatások
Cystatin C is an inhibitor of cysteine proteases including cathepsin B which has been identified as the most important β-amyloid-degrading enzyme. Measurement of cystatin C in serum is replacing creatinine as an indicator of kidney function (glomerular filtration rate, GFR). Studies show its role in predicting new-onset or deteriorating cardiovascular disease. It also seems to play a role in brain disorders involving amyloid, such as Alzheimer′s disease. Cystatin C inhibits transforming growth factor β signaling in normal and cancer cells.
Fizikai forma
Lyophilized from a 0.2 μm filtered solution of 1×PBS
Analízis megjegyzés
The inhibitory function of cystatin c on papain′s protease activity was measured by a colorimetric assay using L-BAPA as substrate. IC50 value was measured at 5 to 20 μg/mL (0.3 to 1.5 μM) with a range of 1.56 μg/mL to 50 μg/mL cystatin C in presence of 0.55 μM papain and 0.44 μM L-BAPA.

Under normal conditions, the function of catalytically active proteases is regulated, in part, by their endogenous inhibitors, and any change in the synthesis and/or function of a protease or its endogenous inhibitors may result in inappropriate protease activity. Altered proteolysis

In patients with acute kidney injury (AKI), serum creatinine level does not increase until moderate to severe reduction in glomerular filtration rate (GFR) occurs. Thus its use for estimating GFR in early AKI delays detection of kidney damage and making
