CASC1 (Cancer Susceptibility Candidate 1), also known as NY-SAR-35 or CT83. is a cancer-testis antigen (CTA) encoded by the *CASC1* gene located on chromosome Xq28. CTAs are proteins typically expressed in germ cells but aberrantly re-expressed in various malignancies, making them potential targets for cancer immunotherapy. CASC1 has garnered attention due to its tumor-specific expression profile, particularly in cancers like breast, lung, and hepatocellular carcinoma, where it correlates with aggressive phenotypes and poor prognosis.
Recombinant CASC1 protein is engineered using biotechnological methods, often expressed in *E. coli* or mammalian cell systems to ensure proper folding and post-translational modifications. The protein’s structure includes conserved domains that may interact with immune cells, suggesting its role in modulating anti-tumor immune responses. Studies highlight its utility in serological diagnostics, as circulating anti-CASC1 antibodies are detected in cancer patients. Additionally, recombinant CASC1 serves as a critical reagent in vaccine development, aiming to stimulate cytotoxic T-cell responses against CASC1-expressing tumors.
Despite its promise, challenges remain, including understanding its precise biological function and optimizing its immunogenicity in therapeutic settings. Research continues to explore its interaction with immune checkpoints and combination therapies. Overall, recombinant CASC1 represents a strategic tool for both mechanistic studies and translational applications in oncology.
