NCIt definition : Human CST6 wild-type allele is located within 11q13 and is approximately 2 kb in length.
This allele, which encodes cystatin M protein, is involved in the inhibition of cysteine
proteases. CST6 gene expression is down-regulated in certain cancers such as breast
carcinomas.;
NCIt note : The CST6 gene is a candidate tumor suppressor gene. In breast cancer cells, ectopic
expression of CST6 has been shown to inhibit cell proliferation, migration, invasion
and tumor growth.;
