Anti-LRMP antibodies are protein reagents that detect specific antigens. The LRMP antigen is another term for the human protein inositol 1,4,5-triphosphate receptor associated 2, encoded by the IRAG2 gene. The protein is reported to play a role in the delivery of peptides to major histocompatibility complex (MHC) class I molecules; this occurs in a transporter associated with antigen processing (TAP)-independent manner. Canonically, it has an amino acid length of 555 residues and a mass of 62.1 kilodaltons. and it is notably expressed at high levels in pre B-cells, mature B-cells and pre T-cells. The LRMP protein is a member of the IRAG2 protein family. Other alias names for LRMP include JAW1 and lymphoid restricted membrane protein. Some LRMP antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
