Target Background

Function (From Uniprot)	Inhibits the activity of interleukin-36 (IL36A,IL36B and IL36G) by binding to receptor IL1RL2 and preventing its association with the coreceptor IL1RAP for signaling. Part of the IL-36 signaling system that is thought to be present in epithelial barriers and to take part in local inflammatory response; similar to the IL-1 system with which it shares the coreceptor. Proposed to play a role in skin inflammation. May be involved in the innate immune response to fungal pathogens, such as Aspergillus fumigatus. May activate an anti-inflammatory signaling pathway by recruiting SIGIRR.
Gene References into Functions	systemic lupus erythematosus patients had significantly decreased serum IL-36Ra levels PMID: 29571080 IL36RN may be the major disease-causing gene in generalized pustular psoriasis patients in Han population in Sichuan region of China. PMID: 30075588 IL36RN mutations were strongly linked with early onset and hyponychial pustules, but not with therapeutic efficacy of acitretin or recurrence frequency. Early onset and hyponychial pustules may be specific to IL36RN mutation, however this alone is an insufficient biomarker for acitretin therapy. PMID: 29619998 Using different blood leukocyte and skin resident cell preparations, and recombinant proteins, the authors have identified that neutrophil elastase, but not other neutrophil derived proteases, cleaves IL-36Ra into its highly active antagonistic form. PMID: 27101808 A study on the association of IL36RN mutations that affect protein expression and function with phenotype in patients with generalized pustular psoriasis. PMID: 27220475 The findings indicate that IL36RN mutations do not seem to contribute to the pathogenesis of common, nonpustular forms of psoriasis, but to the rarer pustular manifestations such as GPP, acrodermatitis continua suppurativa of Hallopeau and acute generalized exanthematous pustulosis. PMID: 27038307 Some cases of geographic tongue are caused by IL36RN mutations, while those lacking mutations are associated with an imbalance in expression between IL-36Ra and IL-36gamma proteins in tongue tissue. PMID: 27900482 Study data and the previous European study suggest that palmoplantar pustulosis is not associated with mutations of the IL36RN gene. PMID: 27542682 Case Report: short-term infliximab for treatment of juvenile generalized pustular psoriasis with IL36RN mutation. PMID: 26627198 The authors present a case of strikingly distinct phenotypes seen in two IL36RN mutation carriers from the same nonconsanguineous pedigree. This mutation it appears may influence the age of onset. PMID: 26147717 The present study identified IL-36RN in various species and investigated the associations between IL-36RN and cancer prognosis. PMID: 26676204 We identified a novel homozygous missense mutation in IL36RN in two siblings, and showed the molecular basis of the condition to be both distinct from psoriasis and distinct between the two families studied. PMID: 25688670 generalized pustular psoriasis and early onset, ever generalized pustular psoriasis (more than two attacks), ever acrodermatitis continua of Hallopeau, inverse psoriasis, and a family history of pustular psoriasis were associated with IL36RN mutation. PMID: 26589685 IL36RN was identified as strong regulators of skin pathology in both lesional and non-lesional skin samples. PMID: 25897967 IL36RN missense mutation was not associated with psoriasis. PMID: 25989471 we report T123M and 115+6T>C mutations, both homozygous in nature, in two Japanese individuals with Zumbusch type of generalized pustular psoriasis. PMID: 25615897 found 2 new variants and 4 known IL36RN variants in 29 generalized pustular psoriasis patients PMID: 25212972 identified a novel IL36RN missense mutation, c.334G > A in exon 5, that caused p.E112K substitution and was located adjacent to a 113 amino acid residue in generalized pustular psoriasis PMID: 25468355 The study found that IL36RN alleles define a generalized pustular psoriasis phenotype characterized by early onset, high risk of systemic inflammation, and low prevalence of psoriasis vulgaris. PMID: 25458002 in a Chinese Daur family with generalized pustular psoriasis, identified a homozygous splice site mutation c.115+6T>C in intron 3 in both patients; other 4 family members and 7 healthy controls carried heterozygous c.115+6T>C mutations PMID: 24979538 Individuals with IL36RN mutations are very susceptible to Generalized pustular psoriasis (GPP) or GPP-related generalized pustulosis induced by drugs. [review] PMID: 24656634 We report two cases of impetigo herpetiformis with homozygous and heterozygous IL36RN mutations. PMID: 24717243 IL-36 promotes myeloid cell infiltration, activation, and inflammatory activity in skin PMID: 24829417 IL36RN variants are unlikely to confer significant disease risk for psoriasis vulgaris. PMID: 23792462 Acrodermatitis is a clinical phenotype of DITRA: evidence a variant of pustular psoriasis... recessively inherited mutations in the IL36RN gene, which encodes interleukin-36 receptor antagonist... the cause of familial GPP, a condition termed DITRA PMID: 23428889 The majority of generalized pustular psoriasis alone is caused by deficiency of the interleukin-36 receptor antagonist due to IL36RN mutations. PMID: 23698098 The percentage of IL36RN mutations of pediatric generalized pustular psoriasis patients was much higher than that of adult onset patients. PMID: 23863864 Our rate of 38.9% IL36RN mutations provides further evidence that generalized pustular psoriasis is heterogenous. PMID: 23648549 IL36RN missense mutations may underlie some forms of acute generalized exanthematous pustulosis. PMID: 23358093 Results indicate that IL36RN mutations are not associated with pustular psoriasis in Chinese populations. PMID: 22862555 Rare pathogenic variants in IL36RN underlie a spectrum of psoriasis-associated pustular phenotypes. PMID: 23303454 Data indicate that IL36RN mutations were identified in 2 of 14 Japanese generalized pustular psoriasis (GPP) patients. PMID: 22903787 The mutation in the interleukin-36-receptor antagonist gene plays a role in generalised pustular psoriasis PMID: 22325761 These data provide evidence that IL-38 binds to the IL-36R, as does IL-36Ra. PMID: 22315422 Interleukin-36 (IL-36) ligands require processing for full agonist (IL-36alpha, IL-36beta, and IL-36gamma) or antagonist (IL-36Ra) activity PMID: 21965679 Mutations in IL36RN/IL1F5 are associated with the severe episodic inflammatory skin disease known as generalized pustular psoriasis. PMID: 21839423 Expression of IL-1F5 is increased in human plaque psoriasis skin and is overexpressed in the lesional psoriatic skin of transgenic mice. PMID: 21242515 results suggest that polymorphisms within IL1RN and IL1L1 themselves or a gene in linkage disequilibrium with IL1RN and IL1L1 predispose to the more severe forms of alopecia areata PMID: 11841485 The commnon variants in the IL-1 cluster gene are not associated with incidence of restenosis in patients after PTCA. PMID: 14644395 IL-1beta-511T was associated with reflux esophagitis having hyperacidity. PMID: 16211343 Data show that the gene expression for interleukin-8, IL-10, and IL-1Ra, but not IL-6, is increased in blood leukocytes taken from athletes following 2 hours of intensive cycling and is not influenced by carbohydrate compared with placebo ingestion. PMID: 16978071 IL-1 delta, which shows striking homology to IL-1 receptor antagonist, specifically and potently inhibits NF-kappa B activation through the orphan IL-1 receptor-related protein 2.
