Human T-cell Surface Protein Tactile, CD96 ELI

May be involved in adhesive interactions of activated T and 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 and NK cells have penetrated the endothelium using integrins and selectins, when they are actively engaging diseased cells and moving within areas of inflammation.
