accession Q9NZH6|express systemE.coli|product tagNo Tag|purity> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC|backgroundIL-37 is a unique member of the IL-1 family of cytokines, which functions as a natural suppressor of inflammatory and immune responses. Immune and non-immune cells produce IL-37 precursor following pro-inflammatory stimuli. Following activating cleavage by caspase-1, mature IL-37 translocates to the nucleus, where it suppresses transcription of pro-inflammatory genes.|molecular weightThe protein has a predicted MW of 18.55 kDa same as Tris-Bis PAGE result.|available size100 g, 500 g|endotoxinLess than 1EU per g by the LAL method.|Human IL-37 Protein 2589proteinSize and concentration100, 500g and lyophilizedFormLyophilizedStorage InstructionsValid for 12 months from date of receipt when stored at -80C.

Signaling can occur via two mechanisms, intracellularly through nuclear translocation with SMAD3 and extracellularly after secretion and binding to its receptor composed of IL18R1 and IL18RAP. Suppresses, or reduces, pro-inflammatory 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.Subellular locationCytoplasm, cytosol. Nucleus. Secreted. Note=Stimulation with IL1B leads to colocalization with SMAD3 mostly in perinuclear regions (PubMed:20935647, PubMed:33674380). Only the CASP1-cleaved mature form translocates into the nucleus upon LPS stimulation (PubMed:18390730). The secretion is dependent on protein unfolding and facilitated by the cargo receptor TMED10; it results in protein translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) followed by vesicle entry and secretion (PubMed:32272059, PubMed:33674380).TissuesIn general, low constitutive expression, if any, in healthy tissues; high expression in inflammatory counterparts, including in synovial tissues from individuals with active rheumatoid arthritis. Isoform A, isoform B and isoform C are expressed in testis, colon, placenta, lung and lymph node. Isoform D and isoform E were found only in testis and bone marrow. Whereas only isoform A is found in brain, only isoform B in kidney and only isoform C in heart.StructureInteracts with SMAD3. Binds IL18R1, but not to IL1R1, with lower affinity than IL18, and does not seem to act as a receptor antagonist for IL18. Interacts with cargo receptor TMED10; the interaction mediates the translocation from the cytoplasm into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) and thereby secretion (PubMed:32272059).Post-translational modificationProteolytically converted to the mature form by CASP1.Target Relevance information above includes information from UniProt accession: Q9NZH6The UniProt Consortium|
