Background

CD96, also known as Tactile (T cell-activated increased late expression), is a 160 kDa type I transmembrane glycoprotein of the Ig superfamily that shows peak expression 6-9 days after activation of T, NK, and a subpopulation of B cells (1, 2). The mature extracellular domain (ECD) of rat CD96 contains three highly N- and O-glycosylated Ig-like domains, with the two N-terminal domains being V-type and the distal domain a C-type structure (1). Within the mature ECD, rat CD96 shares 79% and 52% amino acid sequence identity with mouse and human CD96, respectively. In human, a splice variant with a 16 aa deletion in the second V-type domain, called CD96v2, can be expressed (2). CD96 is also frequently expressed on acute myeloid leukemia and myelodysplastic stem cells (3, 4). It is expressed on CD4+ and CD8+ T cells, plus NK cells and select B cells (5). Low expression of adhesive human CD96 is a rare cause of C syndrome, a set of developmental anomalies in cranial bone (trigonocephaly), skin and viscera, demonstrating a role for CD96 in development of these tissues (2, 6). An 80 kDa soluble form is elevated in human serum during chronic hepatitis B (9). The most N-terminal Ig-like domain of human CD96 binds to CD155/PVR (poliovirus receptor), but CD96/CD155 interaction is species-specific (2, 7, 10). On NK cells, co-stimulatory CD96 and DNAM-1 (CD226) are thought to have paired activity with inhibitory TIGIT, all of which bind CD155 and various nectins (11, 12). CD96 can promote NK cell adhesion to, and killing of target cells, including tumors that express CD155 (10, 11).
