2B4/CD244 Fc Chimera, Human

CD244 (Cluster of Differentiation 244) is a human protein encoded by the CD244 gene. It is also known as Natural Killer Cell Receptor 2B4. This gene encodes a cell surface receptor expressed on natural killer cells (NK cells) (and some T cells) mediating non-major histocompatibility complex (MHC) restricted killing. The interaction between NK-cell and target cells via this receptor is thought to modulate NK-cell cytolytic activity. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. CD244 can also be expressed on non-lymphocytes such as eosinophils, mast cells and dendritic cells.
