Cross Reactivity

There is no detectable cross-reactivity with other relevant proteins.

Specificity

Natural and recombinant human IL-37

Subcellular Localization

Cytoplasm, cytosol. Nucleus. Secreted. Stimulation with IL1B leads to colocalization with SMAD3 mostly in perinuclear regions. Only the CASP1-cleaved mature form translocates into the nucleus upon LPS stimulation.

Protein Function

Suppressor of innate inflammatory and immune responses involved in curbing excessive inflammation. This function requires SMAD3. Suppresses, or reduces, proinflammatory cytokine production, including IL1A and IL6, as well as CCL12, CSF1, CSF2, CXCL13, IL1B, IL23A and IL1RN, but spares anti-inflammatory cytokines. Inhibits dendritic cell activation. .

Background

Interleukin 37 (IL-37) also named IL1F7, is a protein that in humans is encoded by the IL1F7 gene. The protein encoded by this gene is a member of the interleukin 1 cytokine family. And it is mapped to 2q13. In vitro expression analysis showed that IL-37 was a secretory protein. And IL-37 could play an important role in the link between innate and adaptive immunity and may be useful for tumor immunotherapy. Meanwhile, IL-37 inhibits the production of inflammatory cytokines in peripheral blood mononuclear cells of patients with systemic lupus erythematosus. In addition, IL-37 can emerged as a dual-function cytokine with intra- and extracellular properties for suppressing innate inflammation. Furthermore, IL-37 is a new anti-inflammatory cytokine that plays an important role in protecting against tissue injury during infections via limiting immune and inflammatory reactions.

Whereas only isoform A is found in brain, only isoform B in kidney and only isoform C in heart. .
Sequence	Belongs to the IL-1 family.
