IL4R - interleukin 4 receptor Gene
Also Known as CD124; IL4RA; IL-4RA
Species: Homo sapiens
About IL4R
This gene has 19 transcripts (splice variants), 125 orthologues, 7 paralogues and is associated with 2 phenotypes. Broad expression in lymph node (RPKM 30.2), appendix (RPKM 23.9) and 22 other tissues.
Summary
This gene encodes the alpha chain of the interleukin-4 receptor, a type I transmembrane protein that can bind interleukin 4 and interleukin 13 to regulate IgE production. The encoded protein also can bind interleukin 4 to promote differentiation of Th2 cells. A soluble form of the encoded protein can be produced by proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. Allelic variations in this gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitus, asthma, or eczema. Polymorphisms in this gene are also associated with resistance to human immunodeficiency virus type-1 Infection. Alternate splicing results in multiple transcript variants.
