Squamous cell carcinoma antigen is a tumor associated protein of squamous cell carcinoma of various organs. SCCA was originally purified from SCC of the uterine cervix <ref>Martz, E.

SCCA is a tumor marker to detect malignant tumor and to understand biological behaviors of squamous cells. SCCA is classified as a serine protease inhibitor called [http://en.wikipedia.org/wiki/Serpin Serpin] B3. It also inhibits [http://en.wikipedia.org/wiki/Chymotrypsin chymotripsin], [http://en.wikipedia.org/wiki/Cathepsin cathepsin] L, K and S and papain like cysteine proteases. In the case of tumor development SCCA 1 inhibits NK cells(natural killer), TNFalfa and apoptosis of tumor cells induced by treatment. It can also play a role in tumor growth. The chromosomal location is the locus 18q21.3.<ref>PMID:9817978</ref>
