Interleukin 4 receptor (IL-4 R) is the transmembrane ligand binding subunit of the heterodimeric IL-4 receptor complex. In the type I receptor complex, IL-4 R associates with the common gamma chain, whereas in the type II receptor complex, it associates with IL-13 R alpha 1. IL-4 R is expressed by B cells, T cells, monocytes and macrophages.
