What's a GeneRIF?

Most of the natural killer cell p46-related protein (NKp46) and NK cell Lectin-like receptor subfamily A (Ly49A) molecules were restricted to microdomains; however, individual NKp46 molecules resided in these domains for shorter periods and diffused faster on the surface of educated, compared to hyporesponsive, NK cells.
Title: Educated natural killer cells show dynamic movement of the activating receptor NKp46 and confinement of the inhibitory receptor Ly49A.
study found the receptor Ly49A bound the MHC class I molecule H2-M3 with an affinity similar to its affinity for H-2D(d); specific recognition of H2-M3 by Ly49A regulated 'licensing' of NK cells and mediated 'missing-self' recognition of H2-M3-deficient bone marrow
Title: Recognition of the nonclassical MHC class I molecule H2-M3 by the receptor Ly49A regulates the licensing and activation of NK cells.
The difference in frequency of Ly49A-specific natural killer (NK) cells between H2-Dd+/+ and H2-Dd+/2 mice is reflected by a skewed balance between proliferation and apoptosis in this subset.
Title: Skewing of the NK cell repertoire by MHC class I via quantitatively controlled enrichment and contraction of specific Ly49 subsets.
Overexpression of Ly49A enhanced the tumor killing activity of mouse lymphocytes.
Title: [In vitro study of the killing activities on H-2(d) murine normal and tumor cells by Ly49A gene transfected lymphocytes].
The membrane proximal nonligand binding ecto-domain (the stalk region) of Ly49A is critical to ligand binding and signaling.
Title: Essential role of the Ly49A stalk region for immunological synapse formation and signaling.
Ly49A blocks Zap70, extracellular signal-regulated kinase 1/2 and c-Jun activation but leaves unique components of the CD28 signaling pathway intact.
Title: Engagement of transgenic Ly49A inhibits mouse CD4 cell activation by disrupting T cell receptor, but not CD28, signaling.
The association with MHC-I in cis sequestered wild-type Ly49A, and this was found to relieve NK cells from a suppressive effect of unengaged Ly49A
Title: A Role for cis Interaction between the Inhibitory Ly49A receptor and MHC class I for natural killer cell education.
DNA methylation and the histone acetylation state of the Pro-2 promoter region of Ly49a are strictly linked with Ly49a expression status.
Title: Evidence for epigenetic maintenance of Ly49a monoallelic gene expression.
the NK cells' own MHC-I significantly masks the Ly49A and Ly49C, but not the Ly49I receptor
Title: Interactions of Ly49 family receptors with MHC class I ligands in trans and cis.
H-2Dd cis ligand has a role in Ly49A localization to the site of NK cell/target cell contact
Title: Stable masking by H-2Dd cis ligand limits Ly49A relocalization to the site of NK cell/target cell contact.

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.
