DAP10 (HCST/KAP10) was identified as a transmembrane adaptor protein that forms an activating immunoreceptor complex with NKG2D on NK and T cells, recognizing the stress-inducible MHC molecule MICA. The cytoplasmic YINM (YxxM) motif of DAP10 recruits the p85 subunit of PI3-kinase, providing NKG2D-dependent signal transduction. |

DAP10 (KAP10) is genetically linked to DAP12 on human chromosome 19 and, unlike ITAM-containing adaptors, signals via phosphorylation of its cytoplasmic YINM motif to activate PI3K and downstream Akt, rather than recruiting Syk-family kinases. DAP10 can also bind the adaptor protein Grb2. |

Despite high similarity between DAP10 and DAP12, their transmembrane regions are sufficient to confer specific association with distinct ligand-binding receptor partners. DAP10 signals via the PI3K pathway (YxNM motif), while DAP12 signals via Syk/ZAP70 through its ITAM motif. Cross-linking of either DAP10- or DAP12-associated receptors alone can trigger NK cytotoxicity, but synergy occurs in cytokine production when both are co-engaged. |

Pig DAP10 contains conserved structural features including an aspartic acid in the transmembrane domain, two cysteines in the extracellular domain, and a PI3K-binding YxxM motif in the cytoplasmic region. Pig NKG2D requires DAP10 for cell surface expression when transiently transfected into COS-7 cells, demonstrating the conserved requirement for DAP10 in NKG2D surface trafficking. |

A critical YINM amino acid motif in the DAP10 cytoplasmic tail couples NKG2D receptor stimulation to activation of PI3K, Vav1, Rho family GTPases, and phospholipase C, triggering NK cell killing independently of Syk family tyrosine kinases. This defines a Syk-independent activation pathway for ITAM-lacking receptor complexes. |

SIRPβ1 can associate with DAP10 in transfected RBL-2H3 cells, but engagement of SIRPβ1–DAP10 complexes alone does not trigger serotonin release or TNF secretion; instead, DAP10 provides co-stimulatory activity that enhances FcεRI-mediated effector functions under sub-optimal stimulation conditions, demonstrating that DAP10's signaling output is context-dependent. |

Using mice lacking one, two, or all three Vav family proteins, Vav1 deficiency alone is sufficient to disrupt DAP10-mediated NK cell cytotoxicity, whereas Vav2 and Vav3 are preferentially required for FcRγ- and DAP12-mediated cytotoxicity. This places Vav1 specifically downstream of DAP10 in NK cell activation. |

For NKG2D-DAP10-mediated cytotoxicity, both Grb2–Vav1 binding and p85 PI3K binding to the DAP10 YINM motif are required. Grb2–Vav1 binding to DAP10 is sufficient to initiate tyrosine phosphorylation events, but full calcium release and cytotoxicity require the simultaneous recruitment of both Grb2–Vav1 and p85 to the same DAP10 motif. |

Vav1 interacts with DAP10 YINM motifs through the adaptor Grb2 and is required for activation of PI3K-dependent Akt signaling downstream of DAP10. |

DAP10 associates with the myeloid receptor MDL-1, which also associates with DAP12. In osteoclasts and bone marrow-derived macrophages, MDL-1 forms trimolecular complexes with both DAP12 and DAP10 (ITAM/YINM motifs), and DAP10 association with MDL-1 depends almost entirely on DAP12, suggesting DAP12-dependent recruitment of DAP10 into the complex. DAP10-deficient mice become osteopetrotic, confirming DAP10's role in osteoclastogenesis. |

During NK cell activation, exposure to MICB-expressing target cells causes lysosomal degradation of DAP10, with approximately 50% of total NKG2D protein degraded. DAP10 traffics to secretory lysosomes in activated NK cells upon interaction with MICB-expressing targets, and polarization of DAP10-containing secretory lysosomes to the cytotoxic immune synapse is observed, suggesting that rapid DAP10/NKG2D degradation upon synapse formation explains receptor down-regulation after chronic ligand exposure. |

Ly49H must associate with and signal via both DAP10 and DAP12 for optimal NK cell function during MCMV infection. In the absence of DAP12, DAP10 enables Ly49H-mediated target cell killing and proliferation. DAP10-deficient Ly49H+ NK cells show diminished ERK1/2 activation, reduced IFN-γ production, and impaired control of MCMV infection, demonstrating that DAP10 contributes distinct signaling outputs (ERK activation, cytokine production) to the Ly49H receptor complex. |

TREM2/DAP12-dependent activation of PI3K requires DAP10 as a co-signaling adaptor. Ligation of TREM2 activates PI3K, ERK1/2, and Vav3; induces Ca2+ mobilization and actin reorganization; and prevents apoptosis. DAP10 is essential for recruitment of PI3K to the TREM2–DAP12 signaling complex. SHIP1 inhibits this pathway by binding DAP12 via its SH2 domain, preventing PI3K recruitment to DAP12. |

IL-2 and γc cytokines up-regulate DAP10 expression primarily at the posttranscriptional level, increasing DAP10 protein synthesis. Newly synthesized DAP10 undergoes glycosylation that is required for its association with NKG2D and stabilization of NKG2D surface expression. TGF-β1 exerts an opposing dominant effect by inhibiting RNA polymerase II association with the DAP10 promoter, decreasing DAP10 mRNA, which causes secondary loss of NKG2D protein. |

In rodents (rat and mouse), DAP10 and DAP12 associate not with NKG2C/E but with CD94, via a transmembrane lysine residue unique to rodent CD94. This represents a phylogenetic transfer of adaptor-binding capacity from NKG2C/E to the CD94 chain, demonstrating that DAP10 association with NK receptor complexes is mediated by specific transmembrane charged residue interactions. |

DAP10 associates with the receptor for advanced glycation end products (RAGE) in human keratinocytes. RAGE–DAP10 heterodimer formation markedly enhances Akt activation (pro-survival signaling), whereas homomultimeric RAGE interaction leads to caspase-8 activation and apoptosis. Functional blocking of DAP10 in transformed keratinocyte lines abrogates Akt phosphorylation from S100A8/A9-activated RAGE, leading to increased apoptosis. |

The CD200AR–DAP10 pathway shows initial activation followed by transient decrease and reactivation via a positive feedback loop. In vivo studies using DAP10/DAP12 knockout mice confirm that DAP10, but not DAP12, is required for tumor control by this immune checkpoint receptor pathway. |
