Background
-
Function
CD8a (CD8α) is a key component of the CD8 co-receptor and is primarily expressed on cytotoxic CD8+ T cells. By enhancing TCR-MHC I signaling, it promotes T-cell activation, IFN-γ production, and granzyme/perforin-mediated cell killing; it is one of the most commonly used T-cell markers in tumor immunology, infection immunology, vaccine research, and CAR-T cell research.

Subcellular Localization
Cell membrane; Single-pass type I membrane protein; Secreted

Expression
Tissue_specificity:CD8 on thymus-derived T-cells usually consists of a disulfide-linked alpha/CD8A and a beta/CD8B chain. Less frequently, CD8 can be expressed as a CD8A homodimer. A subset of natural killer cells, memory T-cells, intraepithelial lymphocytes, monocytes and dendritic cells expresses CD8A homodimers. Expressed at the cell surface of plasmacytoid dendritic cells upon herpes simplex virus-1 stimulation -
Isoforms & Post-Translational Modification
CD8a has 3 isomers: P01732-1: 25729 Da (predicted); P01732-2: 21585 Da (predicted); P01732-3: 30214 Da (predicted).
Palmitoylated, but association with CD8B seems to be more important for the enrichment of CD8A in lipid rafts;O-glycosylated;Phosphorylated in cytotoxic T-lymphocytes (CTLs) following activation -
Subunit
Forms disulfide-linked heterodimers with CD8B at the cell surface. Also forms homodimers in several cell types including NK-cells or peripheral blood T-lymphocytes.
