VSIG4 (V-set and immunoglobulin domain containing 4)

Gene

• Entrez ID: 11326
• Gene name: V-set and immunoglobulin domain containing 4
• Gene symbol: VSIG4
• Synonyms (NCBI Gene): CRIg, Z39IG
• Chromosome: X
• Chromosome location: Xq12
• Summary: This gene encodes a v-set and immunoglobulin-domain containing protein that is structurally related to the B7 family of immune regulatory proteins. The encoded protein may be a negative regulator of T-cell responses. This protein is also a receptor for th
