    The MHC class I-like Fc receptor (FcRn) functions as an intracellular trafficking receptor, uniquely accountable for prolonging the serum half-life of IgG subclass antibodies and facilitating their passage across cellular barriers. Through these actions, FcRn significantly impacts various aspects of antibody biology and pathobiology. Its crucial role in regulating IgG pharmacokinetics has been exploited in the development of therapeutic antibodies and related biological treatments. Additionally, FcRn is involved in the transport of serum albumin, contributing to the improved pharmacokinetic characteristics of albumin-conjugated therapies. However, a lack of dependable serological tools targeting human FcRn has limited the comprehension of its functions and potential therapeutic uses.

    Background
    The MHC class I-like Fc receptor (FcRn) is an intracellular trafficking Fc receptor that is uniquely responsible for the extended serum half-life of antibodies of the IgG subclass and their ability to transport across cellular barriers. By performing these functions, FcRn affects numerous facets of antibody biology and pathobiology. Its critical role in controlling IgG pharmacokinetics has been leveraged for the design of therapeutic antibodies and related biologics. FcRn also traffics serum albumin and is responsible for the enhanced pharmacokinetic properties of albumin-conjugated therapeutics.
