Ctla-4, also known as cytotoxic T-lymphocyte protein 4 isoform 1, is a type 1 membrane protein and a memberof the immunoglobulin-superfamily. Besides, this protein contains an extra cellular domain, a transmembranedomain and a cytoplasmic tail. It is generally expressed with highest levels in lymphoid tissues. Also, it is similarto T-cell costimulatory protein CD28 since both of the molecules bind to CD80 and CD86 on antigen-presenting cells. CTLA4 and CD28 effectively regulate to T cell responses as opposing signals transmitted through tworelated cell-surface receptors. Recombinant mouse Ctla-4, fused to hIgG-His-Tag at C -terminal, was expressed ininsect cell and purified by using conventional chromatography techniques. Source: Recombinant protein corresponding to aa38-161 from mouse CTLA4, fused to hIgG-His-Tag at C-terminal, expressed in Baculovirus.
