Abbreviation:
B7-H4;VTCN1
Accession:
Q7Z7D3
Background:
B7 Homolog 4 (B7-H4) is glycosylated member of the B7 family of immune costimulatory proteins. Mature human B7-H4 consists of a 235 amino acid (aa) extracellular domain (ECD) with two Ig-like V-type domains; a 21 aa transmembrane segment; and a 2 aa cytoplasmic tail. It is widely expressed; including in kidney; liver; lung; pancreas; placenta; prostate; spleen; testis and thymus. B7-H4 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. It also involved in promoting epithelial cell transformation.
Calculated MW:
51.9 kDa
Endotoxin:
< 1.0 EU per ug of the protein as determined by the LAL method.
