Description:
The CTLA-4 gene is a member of the immunoglobulin superfamily. It is expressed nearly exclusively on the membrane of activated T-cells and plays an important role in the regulation of T-cell immune responses by mediating inhibition of T cell activation. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases. Moreover, a polymorphism in this gene associated with red blood cell alloimmunization among sickle cell disease patients, highlighting a role played by CTLA-4 on post-transfusion antibody development.
