CSTB is a gene encoding the protein cystatin B, also called stefin B. This protein inhibits the function of certain enzymes within the cell and contributes to overall cellular behavior. The effects of specific mutations in CSTB can be difficult to determine because they are not easily measured in cellular models.

Providing modelling and drug screening services for CSTB can be a complicated process. For this reason, we may be limited in our abilities to provide research services for mutations in this gene at this time. Please contact us with interests and inquiries.
