The CTLA-4 protein is a key inhibitory receptor and a major negative regulator of T cell responses in coordination of immune regulation. Its unique property is its significantly increased affinity for B7 ligands (CD80/CD86) compared with CD28. CTLA-4 Protein, Human (HEK293, His) is the recombinant human-derived CTLA-4 protein, expressed by HEK293 , with C-6*His labeled tag.

GMP CTLA-4, a pivotal inhibitory receptor, emerges as a principal negative regulator orchestrating T-cell responses within the intricate framework of immune modulation. This regulatory function stems from the distinctive property of GMP CTLA-4, displaying significantly heightened affinity for its natural B7 family ligands, CD80 and CD86, compared to the cognate stimulatory coreceptor CD28. This pronounced difference in binding affinity positions GMP CTLA-4 to competitively engage with CD80/B7-1 and CD86/B7.2, exerting a suppressive influence on T-cell activation and finely tuning immune responses. The homodimeric structure of GMP CTLA-4, intricately linked by disulfide bonds, further underscores its role as a molecular sentinel in immune regulation. Additionally, GMP CTLA-4 interacts with ICOSLG, contributing to its multifaceted engagement in immune checkpoint pathways.
