Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class I molecule:peptide complex. The antigens presented by class I peptides are derived from cytosolic proteins while class II derived from extracellular proteins. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. LCK then initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of cytotoxic T-lymphocytes (CTLs). This mechanism enables CTLs to recognize and eliminate infected cells and tumor cells. In NK-cells, the presence of CD8A homodimers at the cell surface provides a survival mechanism allowing conjugation and lysis of multiple target cells. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells.

Recombinant CD8 alpha Antibody (Biotin) (Ab213871) - Flow Cytometry Flow cytometry analysis of CD8 alpha expression by C57BL/6 mouse splenocytes (right panel) compared to an isotype control (left panel). Cells were stained with Recombinant CD8 alpha Antibody (Biotin) (Ab213871) at 0.1μg/test for 1 hour at 4°C. Then incubated with Recombinant Streptavidin Protein (R-PE) (rp156150) at 0.1μg/test for 30 minutes at 4°C in the dark. Left panel - Rat IgG (Biotin) (Ab180310).
