CD300a (CMRF-35H, IRp60) is a non-MHC-specific inhibitory receptor of immunoglobulin superfamily, which contains three immunoreceptor tyrosine-based inhibitory motifs (ITIMs) that associate with SH2-containing phosphatases SHP-1 and SHP-2. CD300a is expressed on many cell types including T cells, NK cells, neutrophils, eosinophils or mast cells. Its triggering inhibits activating signals such as those of IL5, GM-CSF or eotaxin, as well as supresses mast cell degranulation or NK cell cytotoxic activity.Synonyms: CD300 antigen-like family member A, CLM-8, CMRF-35-H9, CMRF35-H, CMRF35-H9, CMRF35-like molecule 8, IRC1/IRC2, IRp60, Inhibitory receptor protein 60, NK inhibitory receptor
