Tissue SpecificityWidely expressed with highest levels in lymphoid tissues. Detected in activated T-cells where expression levels are 30- to 50-fold less than CD28, the stimulatory coreceptor, on the cell surface following activation. {ECO:0000269|PubMed:10493833, ECO:0000269|PubMed:16551244, ECO:0000269|PubMed:1713603}.

Subcellular location [CC]Cell membrane {ECO:0000269|PubMed:18468488, ECO:0000269|PubMed:28484017};
Single-pass type I membrane protein {ECO:0000269|PubMed:18468488, ECO:0000269|PubMed:28484017}. Note=Exists primarily an intracellular antigen whose surface expression is tightly regulated by restricted trafficking to the cell surface and rapid internalization.
