Human Interleukin 5 (IL5) is a cytokine produced primarily by activated T lymphocytes. It exists as an antiparallel disulfide-linked homodimeric glycoprotein with 115 amino-acid residues in each chain. Known also as EDG (eosinophil differentiating factor), functions predominantly as an eosinophilopoietic factor. Analysis of its crystal structure reveals a novel two-domain structure, with each domain showing significant homology to the cytokine fold in GM-CSF, M-CSF, IL2, IL4 and growth hormone. Human and mouse IL5 have 70% amino acid sequence homology.
