What is CD96?

CD96 is a type I transmembrane protein that belongs to the immunoglobulin superfamily. The mature protein is 64 kDa and has three extracellular Ig-like domains/loops and a relatively short 45 amino acid cytoplasmic domain. Although many functions of CD96 are unknown, it may play a role in the adhesive interactions of activated T and NK cells during the late phase of the immune response. Interaction with CD155 has also been shown to down-regulate CD96 on the surface of NK cells, potentially through receptor internalization. CD96, a biomarker for acute myeloid leukemia, is highly expressed in T-cell acute lymphoblastic leukemia and myelodysplastic syndromes.

Common detection and analytical methods include flow cytometry, SDS-PAGE, Western Blot mRNA analysis, multiplexed IHF, statistical analysis, and NK and T-cell activation studies.
