Background

Function
CD28/CD80 is a co-stimulatory molecule belonging to the immunoglobulin superfamily that plays a crucial role in T-lymphocyte activation. CD80 interacts with the CD28 receptor-constitutively expressed on the surface of T cells-to serve as a primary co-stimulatory signal that enhances MHC/TCR signaling in naive T cells. This triggers the activation of various signaling pathways, such as NF-κB or MAPK, ultimately leading to the production of multiple cytokines. Furthermore, the CD28/CD80 co-stimulatory signal promotes T-cell glucose metabolism and ATP synthesis by activating the PI3K/Akt signaling pathway. CD80 also acts as a regulator of the PD-L1/PDCD1 interaction, limiting the excessive activation of PD-L1 and its inhibitory effects during immune responses. Expressed on the surface of B cells, CD80 plays a pivotal regulatory role in the interactions between B cells and T cells during both early and late germinal center reactions.

Subcellular Localization
Cell membrane; Single-pass type I membrane protein
-
Expression
Tissue_specificity:It is expressed on activated B cells, macrophages, and dendritic cells. -
Isoforms & Post-Translational Modification
CD80 has 3 isomers: P33681-1: 33048 Da (predicted); P33681-2: 29413 Da (predicted); P33681-3: 18761 Da (predicted).
Palmitoylated by ZDHHC20; palmitoylation protects CD80 from ubiquitin-mediated degradation, regulating the protein stability, and ensures its accurate plasma membrane localization -
Subunit
Homodimer. Interacts with CTLA4; this interaction inhibits T-cell activation. Interacts with PDL1/CD274; this interaction blocks PDL1/PDCD1 binding and thus PDL1/CD274 inhibitory function. Interacts with CD28
