CC -!- FUNCTION: Functions as an activating and costimulatory receptor
CC involved in immunosurveillance upon binding to various cellular stress-
CC inducible ligands displayed at the surface of autologous tumor cells
CC and virus-infected cells. Provides both stimulatory and costimulatory
CC innate immune responses on activated killer (NK) cells, leading to
CC cytotoxic activity. Acts as a costimulatory receptor for T-cell
CC receptor (TCR) in CD8(+) T-cell-mediated adaptive immune responses by
CC amplifying T-cell activation. Stimulates perforin-mediated elimination
CC of ligand-expressing tumor cells. Signaling involves calcium influx,
CC culminating in the expression of TNF-alpha. Participates in NK cell-
CC mediated bone marrow graft rejection. May play a regulatory role in
CC differentiation and survival of NK cells. Binds to ligands belonging to
CC various subfamilies of MHC class I-related glycoproteins (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. Heterohexamer composed of two
CC subunits of KLRK1 and four subunits of HCST/DAP10. Interacts (via
CC transmembrane domain) with HCST/DAP10 (via transmembrane domain); the
CC interaction is required for KLRK1 NK cell surface and induces NK cell-
CC mediated cytotoxicity. Can form disulfide-bonded heterodimer with CD94
CC (By similarity). Interacts with CEACAM1; recruits PTPN6 that
CC dephosphorylates VAV1 (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P26718}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass type II
CC membrane protein {ECO:0000250}. Note=Colocalized with HCST on the cell
CC surface. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Natural killer cells.
CC -!- MISCELLANEOUS: Is not capable of signal transduction by itself, but
CC operates through the adapter protein HCST. {ECO:0000250}.
