(Cytotoxic T-Lymphocyte-Associated Protein 4 (CTLA4))
The cytolytic T-lymphocyte-associated antigen 4 (CTLA-4) is a member of the Ig superfamily (1) and its extracellular domain exhibits a single Ig V-like region. It was originally identified as a fourth cDNA product, during a search for genes that were thought to be specifically expressed in cytotoxic T lymphocytes (1). CTLA-4 has a molecular weight close to 45 kDa (2). It is mainly expressed as a monomer (4), but may also be expressed as a disulfide-linked homodimer (2,3). CTLA-4 belongs to the CD28 receptor family (4,5).Synonyms: CTLA-4, Cytotoxic T-lymphocyte protein 4, Cytotoxic T-lymphocyte-associated antigen 4
