ULBP‑2/5/6 in Human Colon Cancer Tissue. ULBP-2/5/6 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using 10 µg/mL Goat Anti-Human ULBP-2/5/6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1298) overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human ULBP-2/5/6 by Flow Cytometry Rh159 interferes with intracellular transport of NKG2DL.A) Association with Rh159 prevents intracellular transport of MICB. U373-MICB cells were transduced with adenovectors (MOI = 80) expressing either GFP (AdGFP) or FLAG-tagged Rh159 (AdRh159FL) under control of tetracycline-dependent transactivator provided by co-transduced AdtTA (MOI = 20). At 24 hpi cells were metabolically labeled for 30 min with [35S]cysteine + [35S]methionine. Upon chasing the label for the indicated times (h), cells were lysed and MICB was immunoprecipitated with anti–MICB mAb. Precipitates were either digested with EndoH (+) or mock treated (-) followed by SDS-PAGE and autoradiography. (S) indicates EndoH-deglycosylated proteins. B) Rh159 co-immunoprecipitates with MICB. U373-ULBP3 (ULBP3, left panel) or U373-MICB (MICB, right panel) cells were lysed at 48 h post-transduction with AdRh159FL (Rh159) or an adenovector expressing FLAG-tagged SVV ORF 61 (SVV61) used as a negative control. MICB and ULBP3 were immunoprecipitated with anti–MICB and anti-ULBP3 mouse and goat mAbs, respectively, then immunoblotted with mouse anti-FLAG mAb. The mouse IgG heavy chain (55kDa) is indicated (HC). Input lanes were loaded with 10% total lysate used in immunoprecipitation and immunoblotted with mAbs for FLAG and GAPDH. The results shown are representative of two independent experiments. C) Rh159 reduces steady state levels of MICB. U373-MICB cells were lysed at 48 h post-transduction with the indicated Ad-vectors. Lysates were digested with EndoH (+) or mock treated (-) then immunoblotted with mAbs for MICB, FLAG or GAPDH. Note that both MICB and Rh159 are EndoH sensitive consistent with ER localization. The results shown are representative of two independent experiments. D-E) Rh159 reduces surface expression of MICA, MICB, ULBP1 and ULBP2 but not ULBP3. U373-NKG2DL cells were transduced with AdRh159FL or AdGFP as in A) but for 48 h. Cells were then lysed and immunoblotted with mAbs for FLAG and GAPDH (D), or stained with antibodies specific for the indicated proteins, or isotype control (dotted) and analyzed by flow cytometry. The results shown are representative of three or more independent experiments.

Background: ULBP-2/5/6

ULBPs activate multiple signaling pathways in primary NK cells, resulting in the production of cytokines and chemokines. Binding of ULBPs ligands to NKG2D induces calcium mobilization and activation of the JAK2, STAT5, ERK and PI3K kinase/Akt signal transduction pathway. The name ULBP derives from the original identification of three proteins, ULBP-1, -2, and -3, as ligands for the human cytomegalovirus glycoprotein UL16; they were designated UL16 binding proteins (ULBP). The genes for ULBPs reside in a cluster of ten related genes, six of which encode potentially functional glycoproteins. ULBP-2 has also been described under the names RaeT1H (retinoic acid early transcript), NKG2DL2, and ALCAN-alpha. ULBP-5 also known as RaeT1G and ULBP-6 also known as RaeT1L. These proteins are distantly related to MHC class I proteins, but they possess only the alpha 1 and alpha 2 Ig-like domains, and they have no capacity to bind peptide or interact with
beta 2‑microglobulin. Some family members, including ULBP-2, are anchored to the membrane via a GPI-linkage, whereas others have transmembrane domains. Engagement of NKG2D results in the activation of cytolytic activity and/or cytokine production by these effector cells. The ULBPs are expressed on some tumor cells and have been implicated in tumor surveillance. Over aa 26-217, ULBP-2 shares 92% and 95% aa sequence identity with the human ULBP-5 and ULBP-6, respectively.
