CD152:FC (HUMAN)-MULG FUSION PROTEIN 화학적 특성, 용도, 생산
일반 설명
The extracellular domain (160 amino acids) of mouse CD152 is fused to mouse IgG2a Fc domain in which mutations to the complement (C1q) and FcγR I binding sites of the Fcγ2a fragment render the Fc fusion protein incapable of direct antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).
Biochem/physiol Actions
CD152 (CTLA4), a cell surface glycoprotein expressed at low levels on activated T cells, is a high affinity receptor for the costimulatory molecules CD80 (B7-1) and CD86 (B7-2). A related cell surface glycoprotein, CD28, binds to CD80 and CD86 with lower affinity. The soluble CD152/Fc chimeric fusion protein blocks the B7/CD28 signaling pathway by binding to CD80 and CD86.
