N2 - MR1 is a major histocompatibility complex (MHC) class I-related gene conserved among mammals, and its predicted amino acid sequence is relatively closer to the classical MHC class I molecules among several divergent class I molecules. However, as its molecular nature and function have not yet been clarified, we set out in this study to establish transfected P388 murine cell lines that stably produce a large number of MR1 proteins and conducted analyses to investigate the molecular nature of MR1. Immunoprecipitation and Western blot analyses with specific antisera revealed that the MR1 protein can associate with β2-microglobulin, suggesting its molecular form of a typical class I heterodimer composed of a heavy and a light chain (β2-microglobulin), like the classical MHC class I molecules.
