| Uniprot ID: | CTLA4_HUMAN |
| Specificity: | Positive Control: Lymph node or tonsil |
| Immunogen: | Recombinant fragment of human CTLA-4 |
| Tissue Specificity | Widely expressed with highest levels in lymphoid tissues. Detected in activated T-cells where expression levels are 30- to 50-fold less than CD28, the stimulatory coreceptor, on the cell surface following activation. |
| Post Translational Modifications | N-glycosylation is important for dimerization. Phosphorylation at Tyr-201 prevents binding to the AP-2 adapter complex, blocks endocytosis, and leads to retention of CTLA4 on the cell surface. |
| Function | Inhibitory receptor acting as a major negative regulator of T-cell responses. 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. |
