Interactioni

Subunit structurei

Interacts with KLRK1/NKG2D (PubMed:11491531, PubMed:11777960, PubMed:11754823). Does not bind to beta2-microglobulin (By similarity).By similarity3 Publications
(Microbial infection) In CMV-infected cells, interacts with the viral glycoprotein UL16 and UL142; this interaction causes ULBP3 retention in the endoplasmic reticulum and cis-Golgi and prevents binding to and activation of KLRK1/NKG2D, providing CMV with an immune evasion mechanism.1 Publication
