As with many other activating NK cell receptors, NKG2D does not signal on its own but requires a unique signaling adapter, called DAP10.
YINM motif of DAP10 functions as docking site for PI3K, which represents the major effector molecule downstream of NKG2D.
PMID:10426994, 16582911??
Phosphorylated DAP10 directly interacts with regulatory subunit (p85) of PI3K and activates downstream pathway.
Binding of DAP10 to either p85 or Grb2 alone is not sufficient to trigger DAP10-mediated cytotoxicity and that both binding sites are necessary for NKG2D-initiated killing.
