T-cell surface protein tactile; T cell-activated increased late expression protein; cell surface antigen CD96 (CD96)

Function: - may play role in adhesive interactions of activated T cells & NK cells during the late phase of the immune response promotes NK cell-target adhesion by interacting with PVR present on target cells - may function at a time after T & NK cells have penetrated the endothelium using integrins & selectins, when they are actively engaging diseased cells & moving within areas of inflammation - interacts with PVR Structure: - homodimer; disulfide-linked. - contains 1 Ig-like C2-type domain (immunoglobulin-like) - contains 2 Ig-like V-type domain (immunoglobulin-like) Compartment: membrane; single-pass type 1 membrane protein Alternative splicing: named isoforms=2 Expression: - expressed on normal T-cell lines & clones, & some transformed T-cells, but no other cultured cell lines tested - expressed at very low levels on activated B-cells - expressed at low levels on peripheral T-cells & is strongly up-regulated after activation, peaking 6 to 9 days after the activating stimulus Pathology: - chromosomal translocation t(3;18)(q13.13;q12.1) involving CD96 is associated with C syndrome - defects in CD96 are a cause of C-like syndrome
