Aliases:This biomarker is also known as:
- cystatin A (stefin A),
- cystatin AS,
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.

|QA State:||Under Review|
Studies have demonstrated an inverse relationship between increased cathepsin B expression and decreased CSTA in a variety of human tumors. Studies suggest that CSTA is one of the promising candidate biomarkers for lung cancer and deserves further investigation in lung tumorigenesis.
CSTA belongs to a 9-member panel that provides a quantitative measure of the probability of having lung cancer that goes beyond the histological evaluation of preinvasive lesions. The identified members of the panel are TMSB4X (Thymosin beta-4), Ubiquitin, des-ubiquitin, ACBP, CSTA, Cytochrome C, and MIF.
