Interactionⁱ

Subunit structureⁱ

Can form disulfide-bonded heterodimer with NKG2 family members (PubMed:18083576, PubMed:18332182, PubMed:18448674). KLRD1-KLRC1 heterodimer interacts with peptide-bound HLA-E-B2M heterotrimeric complex. KLRD1 plays a prominent role in directly interacting with HLA-E (PubMed:18083576).

Interacts with the adapter protein TYROBP/DAP12; the interaction leads to natural killer cell activation (PubMed:9655483).
