Fcrn albumin binding
WebJan 7, 2024 · IgG and albumin bind to FcRn at distinct sites under acidic but not neutral pH conditions [ 10, 13 ]. FcRn-IgG interaction occurs at CH2 and CH3 and involves two central histidines, H310 and H435 [ 13, 14, 15 ]. These histidine residues are pronated at a pH of ~6 allowing for interaction of FcRn with Glu115 and Asp130.
