Target Details

Target: IL-13 (IL13) (Interleukin 13 (IL13))

Alternative Name: IL-13

Background: Interleukin-13 (IL-13) is a monomeric 17 kDa immunoregulatory cytokine that plays a key role in the pathogenesis of allergy, cancer, and tissue fibrosis. It is secreted by several helper T cell subsets, NK cells, mast cells, eosinophils, basophils, and visceral smooth muscle cells. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Positively regulates IL31RA expression in macrophages (By similarity).

Molecular Weight: 15.3 kDa. Due to glycosylation, the protein migrates to 15 kDa and 25-45 kDa based on Tris-Bis PAGE result.

Pathways: JAK-STAT Signaling, Positive Regulation of Immune Effector Process, Production of Molecular Mediator of Immune Response, Proton Transport
