Compound class: Antibody
Comment: Efmarodocokin alfa is a recombinant human IL-22-Fc IgG4 fusion protein that acts as an agonist of the heterodimeric Interleukin-22α1/10β receptor which is expressed by epithelial cells. It activates the IL-22 signaling pathway without inducing systemic inflammation or causing immunosuppression. Efmarodocokin alfa was developed for potential to treat infectious or inflammatory diseases [2]. The most advanced investigation of its clinical utility has been of its potential to induce repair of the intestinal epithelial damage that is caused by inflammatory bowel diseases [1].

Chemical Modification
The first 146 amino acids are human IL-22, with the remainder constituting the IgG4 Fc chain. There are 4 N-linked glycosylation sites in the IL-22 portion of the peptide, and the Fc region is fucosylated. Structurally efmarodocokin alfa is a dimer of the peptide shown. It has intramolecular disulfide bridges, and intermolecular disulfide bridges that link the subunits. The terminal lysine (K) residue from each chain is clipped.
