{"symbol":"VTCN1","synonyms":["B7H4","B7S1","B7X","B7H.5","VCTN1","B7-H4","PRO1291"],"name":"V-set domain containing T cell activation inhibitor 1","description":"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.
