LY96 (lymphocyte antigen 96)

Gene

• Entrez ID: 23643
• Gene name: Lymphocyte antigen 96
• Gene symbol: LY96
• Synonyms: ESOP-1, MD-2, MD2, ly-96
• Chromosome: 8
• Chromosome location: 8q21.11
• Summary: This gene encodes a protein which associates with toll-like receptor 4 on the cell surface and confers responsiveness to lipopolysaccyaride (LPS), thus providing a link between the receptor and LPS signaling. Studies of the mouse ortholog suggest that thi
