Immunoglobulin superfamily member 8 is a protein that in humans is encoded by the IGSF8 gene. IGSF8 has also been designated as CD316 (cluster of differentiation 316). IGSF8 is an innate immune checkpoint that inhibits the cytotoxic activity of natural killer (NK) cells. IGSF8 acts by binding to the Killer Ig-like Receptor KIR3DL2 (or, in mice, the analogous Klra9 receptor). IGSF8 is frequently overexpressed relative to normal tissues in many cancers, included melanoma, urothelial carcinoma, and breast cancer, and has been proposed as a potential therapeutic target in gliomas. In normal tissues, IGSF8 is highly expressed in the brain, where it may contribute to the immune privilege of the central nervous system.
