Structure and function of the non-classical major histocompatibility complex molecule MR1.

ABSTRACT: Polymorphic major histocompatibility complex (MHC) molecules play a central role in the vertebrate adaptive immune system. By presenting short peptides derived from pathogen-derived proteins, these "classical" MHC molecules can alert the T cell branch of the immune system of infected cells and clear the pathogen. There exist other "non-classical" MHC molecules, which while similar in structure to classical MHC proteins, are contrasted by their limited polymorphism. While the functions of many class Ib MHC molecules have still to be elucidated, the nature and diversity of antigens (if any) that some of them might present to the immune system is expected to be more restricted and might function as another approach to distinguish self from non-self. The MHC-related 1 (MR1) molecule is a membe
