    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. Clearance of lung cancer is facilitated by up-regulation of NKG2D, NKp46, and other activating receptors upon exposure to environmental MHCI. Surface expression of the inhibitory receptor Ly49C/I, on the other hand, is down-regulated upon exposure to tumor-bearing tissue.
      Title: Modulation of NKG2D, NKp46, and Ly49C/I facilitates natural killer cell-mediated control of lung cancer.
    2. NK cells' own MHC-I significantly masks the Ly49A and Ly49C, but not the Ly49I receptor. Nevertheless, Ly49I was partly masked on transfected tumor cells, suggesting that the structure of Ly49I is compatible in principal with cis binding of MHC-I.
      Title: Interactions of Ly49 family receptors with MHC class I ligands in trans and cis.
    3. mouse cytomegalovirus(MCMV) m157 protein binds to Ly49I

    4. Crystal structure of the Ly49I natural killer cell receptor reveals variability in dimerization mode within the Ly49 family.
      Title: Crystal structure of the Ly49I natural killer cell receptor reveals variability in dimerization mode within the Ly49 family.
    5. Contrary to findings in other inhibitory LY49 transgenic systems, no defects in T cell function are observed in Ly49I transgenic FVB mice.
      Title: B6 strain Ly49I inhibitory gene expression on T cells in FVB.Ly49IB6 transgenic mice fails to prevent normal T cell functions.
    6. The repertoire of inhibitory Ly49 receptors may be formed under the influenced of Fyn-dependent NK cell activation as well as the respective MHC class I environment.

    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.
