Background Information
COSMC (C1GALT1C1) is a molecular chaperone required for expression of active T-synthase (CIGALT1) which catalyzes the synthesis of Tn antigen. Tn antigens are cancer-associated glycans and play an important role in tumor progression. Dysfunctional COSMC is able to convert a wild type protein into a tumor-specific antigen affecting tumor cell biology. COSMC overexpression had been observed in various cancers. COSMC mutations have been observed in an autoimmune disease Tn syndrome.
