target relevance
B7-H4, also known as B7x and B7S1, is a 50-80 kDa glycosylated member of the B7 family of immunomodulatory proteins.B7-H4 is up-regulated in several carcinomas in correlation with tumor progression and metastasis. A soluble form of B7-H4 is elevated in the serum of ovarian cancer, renal cell carcinoma, and rheumatoid arthritis patients, also in correlation with advanced disease status.
Protein names
V-set domain-containing T-cell activation inhibitor 1 (B7 homolog 4) (B7-H4) (B7h.5) (Immune costimulatory protein B7-H4) (Protein B7S1) (T-cell costimulatory molecule B7x)
Gene names
Protein family
Immunoglobulin superfamily, BTN/MOG family
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. {ECO:0000250|UniProtKB:Q7TSP5, ECO:0000269|PubMed:15878339, ECO:0000269|PubMed:16606666, ECO:0000269|PubMed:17509674, ECO:0000269|PubMed:17875732}.
Subellular location
SUBCELLULAR LOCATION: Cell membrane {ECO:0000255}; Single-pass type I membrane protein {ECO:0000305}. Note=Expressed at the cell surface. A soluble form has also been detected. {ECO:0000255, ECO:0000269|PubMed:12818165, ECO:0000269|PubMed:15878339, ECO:0000269|PubMed:16782226}.
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. {ECO:0000269|PubMed:12818165, ECO:0000269|PubMed:14568939, ECO:0000269|PubMed:15878339, ECO:0000269|PubMed:16606666, ECO:0000269|PubMed:16782226, ECO:0000269|PubMed:16798883, ECO:0000269|PubMed:17509674}.
Post-translational modification
PTM: N-glycosylated. {ECO:0000269|PubMed:15878339}.
