Protein function

Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing.

Protein tissue specificity

Isoform 1, isoform 3, isoform 5, isoform 6, isoform 7 and isoform 8 are expressed in both thymus and peripheral CD8+ T-cells. Expression of isoform 1 is higher in thymus CD8+ T-cells than in peripheral CD8+ T-cells. Expression of isoform 6 is higher in peripheral CD8+ T-cells than in thymus CD8+ T-cells.

Protein sequence and domain

Contains 1 Ig-like V-type (immunoglobulin-like) domain.

Protein post-translational modifications

Phosphorylated as a consequence of T-cell activation.

Protein cellular localization

Isoform 1: Cell membrane ; Single-pass type I membrane protein .; Isoform 2: Cell membrane ; Single-pass type I membrane protein .; Isoform 3: Secreted .; Isoform 4: Cell membrane ; Single-pass type I membrane protein .; Isoform 5: Cell membrane ; Single-pass type I membrane protein .; Isoform 6: Secreted .; Isoform 7: Secreted .; Isoform 8: Secreted .


The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T-cell receptor on the T lymphocyte recognize antigens displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. The functional coreceptor is either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 beta chain isoforms. Multiple alternatively spliced transcript variants encoding distinct membrane associated or secreted isoforms have been described. A pseudogene, also located on chromosome 2, has been identified.
