Aliases:This biomarker is also known as:
- cystatin AS,
- cystatin A (stefin A),
CSTA, or cystatin-A, is a member of the cystatin superfamily, which includes proteins that contain multiple cystatin-like sequences. Some members of the cystatin superfamily are active cysteine protease inhibitors, of which there are three families: type 1 cystatins (stefins), type 2 cystatins, and kininogens. CSTA is a stefin that functions as a cysteine protease inhibitor, forming tight complexes with papain and the cathepsins B, H, and L. Stefins have been proposed as prognostic and diagnostic biomarkers for cancer.
