This product is an active protein and may elicit a biological response in vivo, handle with caution.
Reconstitution Reconstitute in 5-10 mM HCl to a concentration of 0.1 µg/µl. The solution can then be diluted into other aqueous buffers.
Function Cytokine (PubMed:8096327, PubMed:8097324). Inhibits inflammatory cytokine production (PubMed:8096327). Synergizes with IL2 in regulating interferon-gamma synthesis (PubMed:8096327). May be critical in regulating inflammatory and immune responses (PubMed:8096327, PubMed:8097324). Positively regulates IL31RA expression in macrophages.
Involvement in disease Allergic rhinitis
Sequence similarities Belongs to the IL-4/IL-13 family.
Cellular localization Secreted.
