V-set domain containing T-cell activation inhibitor 1
Alias
B7-H4 | B7H4 | B7S1 | B7X | B7h.5 | PRO1291 | VCTN1
This gene encodes a protein belonging to the B7 costimulatory protein family. Proteins in this family are present on the surface of antigen-presenting cells and interact with ligand bound to receptors on the surface of T cells. Studies have shown that high levels of the encoded protein has been correlated with tumor progression. A pseudogene of this gene is located on chromosome 20. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011].
