| Uniprot ID: |
CD80_HUMAN |
| Immunogen Region: |
ECD |
| Immunogen: |
Optimized DNA sequence encoding Human extracellular domain of human CD80including a C-terminal 6His tag was expressed in HEK293 cells. NA |
| Tissue Specificity | Expressed on activated B-cells, macrophages and dendritic cells. |
| Post Translational Modifications | Palmitoylated by ZDHHC20.palmitoylation protects CD80 from ubiquitin-mediated degradation, regulating the protein stability, and ensures its accurate plasma membrane localization. |
| Function | Costimulatory molecule that belongs to the immunoglobulin superfamily that plays an important role in T-lymphocyte activation. Acts as the primary auxiliary signal augmenting the MHC/TCR signal in naive T-cells together with the CD28 receptor which is constitutively expressed on the cell surface of T-cells. In turn, activates different signaling pathways such as NF-kappa-B or MAPK leading to the production of different cytokines. In addition, CD28/CD80 costimulatory signal stimulates glucose metabolism and ATP synthesis of T-cells by activating the PI3K/Akt signaling pathway. Acts also as a regulator of PDL1/PDCD1 interactions to limit excess engagement of PDL1 and its inhibitory role in immune responses. Expressed on B-cells, plays a critical role in regulating interactions between B-cells and T-cells in both early and late germinal center responses, which are crucial for the generation of effective humoral immune responses. (Microbial infection) Acts as a receptor for adenovirus subgroup B. |
