Background	Cytotoxic T-lymphocyte protein 4 (CD152/CTLA4) is a ~24 kDa protein. Inhibitory receptor acting as a major negative regulator of T-cell responses. Acts as a decoy receptor: the affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28. CD152 is the therapeutic target of ipilimumab (Yervoy). 1. Schwartz, JC. et al. (2001) Nature 410, 604-8. PMID: 11279501 2. Stamper, CC. et al. (2001) Nature 410, 608-11. PMID: 11279502 3.
