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. SUBUNIT: In general heterodimer of an alpha and a beta chain linked by two disulfide bonds. SUBCELLULAR LOCATION: Isoform 1: Cell membrane; Single-pass type I membrane protein (Probable). SUBCELLULAR LOCATION: Isoform 2: Cell membrane; Single-pass type I membrane protein (Probable). SUBCELLULAR LOCATION: Isoform 3: Secreted (Probable). SUBCELLULAR LOCATION: Isoform 4: Cell membrane; Single-pass type I membrane protein (Probable). SUBCELLULAR LOCATION: Isoform 5: Cell membrane; Single-pass type I membrane protein (Probable). SUBCELLULAR LOCATION: Isoform 6: Secreted (Probable). SUBCELLULAR LOCATION: Isoform 7: Secreted (Probable). SUBCELLULAR LOCATION: Isoform 8: Secreted (Probable).

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. PTM: Phosphorylated as a consequence of T-cell activation (Potential). SIMILARITY: Contains 1 Ig-like V-type (immunoglobulin-like) domain.
