UniProtKB - Q7Z7D3 (VTCN1_HUMAN)
Protein
V-set domain-containing T-cell activation inhibitor 1
Gene
VTCN1
Organism
Homo sapiens (Human)
Status
Functioni
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.By similarity4 Publications
Miscellaneous
May serve as a predictive marker for renal cell carcinoma.1 Publication
Caution
The mouse ortholog has been shown 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.Curated

Expressioni
Tissue specificityi
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.7 Publications
