Also known as: CD223
Summary: Predicted to enable MHC class II protein binding activity and transmembrane signaling receptor activity. Predicted to be involved in several processes, including innate immune response; negative regulation of regulatory T cell differentiation; and plasmacytoid dendritic cell activation. Predicted to act upstream of or within negative regulation of T cell activation; negative regulation of interleukin-2 production; and positive regulation of natural killer cell mediated cytotoxicity. Predicted to be located in external side of plasma membrane and extracellular region. Predicted to be active in cell surface and plasma membrane. Orthologous to human LAG3 (lymphocyte activating 3).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
