General annotation (Comments)
| Function | Negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. Involved in promoting epithelial cell transformation. Ref.12 Ref.13 Ref.16 Ref.17 UniProtKB Q7TSP5 |
| Subcellular location | Cell membrane; Single-pass type I membrane protein Potential. Note: Expressed at the cell surface. A soluble form has also been detected. Ref.1 Ref.3 Ref.12 |
| Tissue specificity | Overexpressed in breast, ovarian, endometrial, renal cell (RCC) and non-small-cell lung cancers (NSCLC). Expressed on activated T- and B-cells, monocytes and dendritic cells, but not expressed in most normal tissues (at protein level). Widely expressed, including in kidney, liver, lung, ovary, placenta, spleen and testis. Ref.1 Ref.3 Ref.11 Ref.12 Ref.13 Ref.15 Ref.17 |
| Induction | Up-regulated by IL6/interleukin-6 and IL10/interleukin-10 and inhibited by CSF2/GM-CSF and IL4/interleukin-4 on antigen-presenting cells (APCs). Ref.13 Ref.14 Ref.16 |
| Post-translational modification | N-glycosylated. Ref.12 |
| Miscellaneous | May serve as a predictive marker for renal cell carcinoma. Ref.15 |
| Sequence similarities | Belongs to the immunoglobulin superfamily. BTN/MOG family. UniProtKB Q5ZPR3 Contains 2 Ig-like V-type (immunoglobulin-like) domains. |
| Caution | The mouse ortholog has been shown (PubMed:12818166) to be a GPI-anchored protein but the Gly residue which is predicted to be the modified site in mouse and rat is not conserved in human. |
