		Technical Data
H1827-45B	HCST (DAP10, Hematopoietic Cell Signal Transducer, DNAX-activation Protein 10, Membrane Protein DAP10, Transmembrane Adapter Protein KAP10, KAP10, PIK3AP, UNQ587/PRO1157)

Description:
Transmembrane adapter protein which associates with NKG2D to form an activation receptor NKG2D-HCST in lymphoid and myeloid cells; this receptor plays a major role in triggering cytotoxicity against target cells expressing cell surface ligands such as MHC class I chain-related MICA and MICB, and UL16-binding proteins (ULBPs); these ligands are up-regulated by stress conditions and pathological state such as viral infection and tumor transformation. Functions as docking site for PI3-kinase PIK3R1 and GRB2. Interaction of ULBPs with NKG2D-DAP10 triggers calcium mobilization and activation of the PIK3R1, MAP2K/ERK, and JAK2/STAT5 signaling pathways. Both PIK3R1 and GRB2 are required for full NKG2D-HCST-mediated activation and ultimate killing of target cells. In NK cells, NKG2D-HCST signaling directly induces cytotoxicity and enhances cytokine production initiated via DAP12/TYROBP-associated receptors. In T-cells, it provides primarily costimulation for TCR-induced signals. NKG2D-HCST receptor plays a role in immune surveillance against tumors and is required for cytolysis of tumors cells; indeed, melanoma cells that do not express NKG2D ligands escape from immune surveillance mediated by NK cells.
