Webb15 maj 2000 · The CH2-CH3 interface of the IgG Fc domain contains the binding sites for a number of Fc receptors including Staphylococcal protein A and the neonatal Fc receptor (FcRn). It has recently been proposed that the CH2-CH3 interface also contains the principal binding site for an isoform of the low affinity IgG Fc receptor II (FcγRIIb). Webb20 juni 2024 · A series of substituted indolo[2,1-a]isoquinolines and indolo[1,2-a]benzoxazines have been prepared, as melatonin analogues, to investigate the nature of the binding site of the melatonin receptor. Agonist and antagonist potency of all the analogues was measured using the [35S]GTPγS binding assay pr …
