15. There is an association between the levels of sCD89-IgA complexes in serum and the severity of IgA nephropathy, and a possible genetic component in regulating the production or expression of sCD89. PMID: 20811333
16. Endocytosis of FcalphaR is clathrin- and dynamin-dependent, but is not regulated by Rab5, and the endocytic motif is not located in the cytoplasmic domain of FcalphaR. PMID: 19859085
17. CD89 circulates in a high molecular mass form in complex covalently linked to IgA and contributes to the formation of polymeric serum IgA. PMID: 11801662
18. study suggests that expression of the FcR splice isoform DeltaEC2 but not Delta66EC2 is differentially regulated in a cell type-specific manner and in response to inflammatory and/or infectious processes PMID: 12560105
19. The Fc alpha receptor 5'-flanking region from -102 to -64 relative to the ATG translation initiation codon is essential for promoter activity and contains two functional binding motifs for C/EBP and Ets family members at -74 and -92, respectively. PMID: 12594283
20. there is a bivalent, pH-dependent interaction between FcalphaRI and IgA with important implications for cytokine-dependent phagocytosis of IgA and the FcalphaRI-mediated degradation or recycling of IgA PMID: 12634059
21. crystal structures of human FcalphaRI alone and in a complex with the Fc region of IgA1 (Fcalpha) PMID: 12768205
22. Crystal structure of the ectodomain of human FcalphaRI PMID: 12783876
23. expression pattern of CD89 and its signalling subunit, the FcR gamma chain, on circulating myeloid cells and in various tissues PMID: 12791088
24. FcalphaRI expressed by interstitial-type dendritic cells could play a critical role to sample IgA-recognized antigens and also during dendritic cell activation. PMID: 15371488
25. Pathogenic group A and group B streptococci are well known to produce virulence factors that block the binding of IgA to the leukocyte IgA receptor, Fc alphaRI, thereby inhibiting IgA-mediated immunity. PMID: 16293625
26. Fc receptor gamma RI interacts with the unrelated immunoreceptors FcalphaRI and FcepsilonRI [FCalphaRI, also called CD89] PMID: 16627486
27. These results indicate that GPVI is unique amongst the receptors of its family as it uses different structural domains to interact with several agonists and provide evidence that different sites on GPVI constitute targets to develop antagonists of GPVI. PMID: 16876821
28. On monomeric targeting, FcalphaRI functions as an FcRgamma ITAM-dependent apoptotic module that may be fundamental for controlling inflammation and tumor growth. PMID: 16990604
