What's a GeneRIF?

CD300c could be considered a biomarker and therapeutic target in patients with IgE-mediated allergic diseases
Title: CD300c costimulates IgE-mediated basophil activation, and its expression is increased in patients with cow's milk allergy.
Administration of CD300c-Fc protein attenuates graft-vs.-host disease (GVHD) in mice.
Title: A CD300c-Fc Fusion Protein Inhibits T Cell Immunity.
Results show that CD300c is exclusively expressed on CD56bright natural killer cells and differentially binds to phosphatidylethanolamine and phosphatidylserine. This expression is under the regulation of STAT5 and Il-4.
Title: CD300c is uniquely expressed on CD56 bright Natural Killer Cells and differs from CD300a upon ligand recognition.
potential role in inflammatory responses
Title: CD300c is an activating receptor expressed on human monocytes.
engagement of CD300C led to Fc receptor gamma-dependent activation of mast cells and monocytes
Title: Human CD300C delivers an Fc receptor-γ-dependent activating signal in mast cells and monocytes and differs from CD300A in ligand recognition.
differential expression on human TH1 and TH17 cell memory subsets
Title: Differential expression of CD300a/c on human TH1 and TH17 cells.
CD300a and CD300c receptors are indistinguishable on the surface of natural killer (NK) cells. The tyrosine residue in the third ITIM motif, Tyr-267-Ala, is the most important residue for execution of the inhibitory signal.
Title: Expression and function of CD300 in NK cells.
CD300a and CD300c play an important role in the cross-regulation of TNF-alpha and IFN-alpha secretion from pDCs; CD300a/c RNA and surface expression were downregulated after stimulation of pDCs with TLR7 and TLR9 ligands
Title: CD300a/c regulate type I interferon and TNF-alpha secretion by human plasmacytoid dendritic cells stimulated with TLR7 and TLR9 ligands.
CMRF35A and CMRF35H have roles in immunoglobulin signaling; CMRF35A induces cellular activation and effector function [review]

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.
