    • 基因功能参考文献:
      1. High ULBP2 expression is associated with lymphoma. PMID: 27477692
      2. IMP3 directly interacts with ULBP2 mRNA, leading to ULBP2 transcript destabilization and reduced ULBP2 surface expression and indirectly downregulates MICB with a mechanism functionally distinct from that of ULBP2. PMID: 26982091

      4. human tumor cells lost their surface expression of ULBP2, but not ULBP1 and ULBP3, during NK cell-mediated cytolysis. PMID: 24614922
      5. This study suggests that NKG2D ligands shedding of MICA, MICB and ULBP-2 is a novel pathway in endometriosis complex pathogenesis that impairs Natural Killer Cells cell function. PMID: 25775242

      8. Human anaplastic thyroid carcinoma cells are sensitive to NK cell-mediated lysis via ULBP2/5/6 and chemoattract NK cells. PMID: 25212604
      9. Data inticate that heat shock protein 60 (HSP60) interacted constitutively with NKG2D ligand ULBP2 and phosphatase of regenerating liver 3 (PRL-3) regulated HSP60 tyrosine phosphorylation. PMID: 25687758
      10. Results suggest that ULBP2 is expressed and released from cervical cancer cells by CRF, which regulates NKG2D expression in natural killer cells. PMID: 24841552

      26. ULBP2 was seen on 82.9% of ovarian cancer cells but not on normal ovarian epithelium. Strong expression of ULBP2 in these cells correlated with less intraepithelial infiltration of T cells & may relate to T cell dysfunction in the tumor microenvironment. PMID: 18791713

      29. RAET1G, like ULBP2, appears broadly expressed, but exhibits a lower apparent avidity for NKG2D due to a mutation in the center of the MHC-like fold. PMID: 19424970
      30. Data show upon HSV-1 infection of cell lines, surface levels of NKG2D ligands MICA antigen and UL16 binding protein 2 were downmodulated due to late viral ICP0 gene product(s). PMID: 19508374
