Protein Information
Name IL4
Function Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes.
Cellular Location Secreted.

Interleukin-4 (IL-4) is a principal regulatory cytokine during an immune response and a crucial determinant for allergy and asthma. IL-4 binds with high affinity and specificity to the ectodomain of the IL-4 receptor alpha chain (IL4-BP). IL-4 is a left-handed four-helix bundle with a short stretch of beta sheet. The structure bears close resemblance to other cytokines such as granulocyte-macrophage colony stimulating factor (GM-CSF). Regions have been identified which are not only important to maintain structure, but could also play a role in receptor binding (2). IL-4 antagonists Y124D and Y124G are presented and shown to be medically important. The site around Y124 is a particularly important epitope responsible for the ability of IL-4 to cause a signal in the target cells (3).
