WebMar 8, 2024 · Inspection of the binding interface of albumin with FcRn 20, 21 has allowed design of recombinant variants with different FcRn affinities by single-point amino acid mutations that have been... WebApr 14, 2024 · FcRn binds to the Fc domain of IgGs at acidic pH (pH <6.5), but only minimally at neutral or basic pH (pH ≥7.0). This pH-dependent binding property allows FcRn to bind to internalized IgGs in acidic endosomes and transport them back to the cell surface, where they are released into the circulation at physiological pH (pH ~7.4).
