Interleukin-36 gamma previously known as interleukin-1 family member 9 (IL1F9) is a protein that in humans is encoded by the IL36G gene.{{cite journal | vauthors = Busfield SJ, Comrack CA, Yu G, Chickering TW, Smutko JS, Zhou H, Leiby KR, Holmgren LM, Gearing DP, Pan Y | title = Identification and gene organization of three novel members of the IL-1 family on human chromosome 2 | journal = Genomics | volume = 66 | issue = 2 | pages = 213–6 | date = June 2000 | pmid = 10860666 | doi = 10.1006/geno.2000.6184 }}{{cite journal | vauthors = Kumar S, McDonnell PC, Lehr R, Tierney L, Tzimas MN, Griswold DE, Capper EA, Tal-Singer R, Wells GI, Doyle ML, Young PR | title = Identification and initial characterization of four novel members of the interleukin-1 family | journal = The Journal of Biological Chemistry | volume = 275 | issue = 14 | pages = 10308–14 | date = April 2000 | pmid = 10744718 | doi = 10.1074/jbc.275.14.10308 | doi-access = free }}{{cite journal | vauthors = Nicklin MJ, Barton JL, Nguyen M, FitzGerald MG, Duff GW, Kornman K | title = A sequence-based map of the nine genes of the human interleukin-1 cluster | journal = Genomics | volume = 79 | issue = 5 | pages = 718–25 | date = May 2002 | pmid = 11991722 | doi = 10.1006/geno.2002.6751 }}{{cite journal | vauthors = Taylor SL, Renshaw BR, Garka KE, Smith DE, Sims JE | title = Genomic organization of the interleukin-1 locus | journal = Genomics | volume = 79 | issue = 5 | pages = 726–33 | date = May 2002 | pmid = 11991723 | doi = 10.1006/geno.2002.6752 }}
Expression
IL36G is well-expressed in the epithelium of the skin, gut, and lung.{{cite journal | vauthors = Yuan ZC, Xu WD, Liu XY, Liu XY, Huang AF, Su LC | title = Biology of IL-36 Signaling and Its Role in Systemic Inflammatory Diseases | journal = Frontiers in Immunology | volume = 10 | pages = 2532 | date = 2019 | pmid = 31736959 | doi = 10.3389/fimmu.2019.02532 | pmc = 6839525 | doi-access = free }} In the skin IL36G is predominantly expressed in epidermal granular layer keratinocytes with little to no expression in basal layer keratinocytes.{{cite journal | vauthors = Merleev A, Ji-Xu A, Toussi A, Tsoi LC, Le ST, Luxardi G, Xing X, Wasikowski R, Liakos W, Brüggen MC, Elder JT, Adamopoulos IE, Izumiya Y, Leal AR, Li Q, Kuzminykh NY, Kirane A, Marusina AI, Gudjonsson JE, Maverakis E | display-authors = 6 | title = Proprotein convertase subtilisin/kexin type 9 is a psoriasis-susceptibility locus that is negatively related to IL36G | journal = JCI Insight | volume = 7 | issue = 16 | date = August 2022 | pmid = 35862195 | doi = 10.1172/jci.insight.141193 | pmc = 9462487 }}
Function
The protein encoded by this gene is a member of the interleukin-1 cytokine family. This gene and eight other interleukin-1 family genes form a cytokine gene cluster on chromosome 2.{{cite journal | vauthors = Garlanda C, Dinarello CA, Mantovani A | title = The interleukin-1 family: back to the future | journal = Immunity | volume = 39 | issue = 6 | pages = 1003–18 | date = December 2013 | pmid = 24332029 | pmc = 3933951 | doi = 10.1016/j.immuni.2013.11.010 }} The activity of this cytokine is mediated via the interleukin-1 receptor-like 2 (IL1RL2/IL1R-rp2/IL-36 receptor), and is specifically inhibited by interleukin-36 receptor antagonist, (IL-36RA/IL1F5/IL-1 delta). Interferon-gamma, tumor necrosis factor-alpha and interleukin-1 β (IL-1β) are reported to stimulate the expression of this cytokine in keratinocytes. The expression of this cytokine in keratinocytes can also be induced by a multiple Pathogen-Associated Molecular Patterns (PAMPs).{{cite journal | vauthors = Gabay C, Towne JE | title = Regulation and function of interleukin-36 cytokines in homeostasis and pathological conditions | journal = Journal of Leukocyte Biology | volume = 97 | issue = 4 | pages = 645–52 | date = April 2015 | pmid = 25673295 | doi = 10.1189/jlb.3RI1014-495R | s2cid = 36594830 | doi-access = free }} Both IL-36γ mRNA and protein have been linked to psoriasis lesions and has been used as a biomarker for differentiating between eczema and psoriasis.{{cite journal | vauthors = Berekméri A, Latzko A, Alase A, Macleod T, Ainscough JS, Laws P, Goodfield M, Wright A, Helliwell P, Edward S, Brown GD, Reid DM, Wenzel J, Stacey M, Wittmann M | display-authors = 6 | title = Detection of IL-36γ through noninvasive tape stripping reliably discriminates psoriasis from atopic eczema | journal = The Journal of Allergy and Clinical Immunology | volume = 142 | issue = 3 | pages = 988–991.e4 | date = September 2018 | pmid = 29782895 | pmc = 6127028 | doi = 10.1016/j.jaci.2018.04.031 | url = http://aura.abdn.ac.uk/bitstream/2164/10849/3/Detection_of_IL_36_through_noninvasive_tape_stripping_reliably_discriminates_psoriasis_from_atopic_eczema_2_.pdf | hdl = 2164/10849 }}{{cite journal | vauthors = D'Erme AM, Wilsmann-Theis D, Wagenpfeil J, Hölzel M, Ferring-Schmitt S, Sternberg S, Wittmann M, Peters B, Bosio A, Bieber T, Wenzel J | display-authors = 6 | title = IL-36γ (IL-1F9) is a biomarker for psoriasis skin lesions | journal = The Journal of Investigative Dermatology | volume = 135 | issue = 4 | pages = 1025–1032 | date = April 2015 | pmid = 25525775 | doi = 10.1038/jid.2014.532 | doi-access = free }} As with many other interleukin-1 family cytokines IL-36γ requires proteolytic cleavage of its N-terminus for full biological activity.{{cite journal | vauthors = Towne JE, Renshaw BR, Douangpanya J, Lipsky BP, Shen M, Gabel CA, Sims JE | title = Interleukin-36 (IL-36) ligands require processing for full agonist (IL-36α, IL-36β, and IL-36γ) or antagonist (IL-36Ra) activity | journal = The Journal of Biological Chemistry | volume = 286 | issue = 49 | pages = 42594–602 | date = December 2011 | pmid = 21965679 | pmc = 3234937 | doi = 10.1074/jbc.M111.267922 | doi-access = free }} However, unlike IL-1β the activation of IL-36γ is inflammasome-independent. IL-36γ is specifically cleaved by the endogenous protease cathepsin S as well exogenous proteases derived from fungal and bacterial pathogens.{{cite journal | vauthors = Ainscough JS, Macleod T, McGonagle D, Brakefield R, Baron JM, Alase A, Wittmann M, Stacey M | display-authors = 6 | title = Cathepsin S is the major activator of the psoriasis-associated proinflammatory cytokine IL-36γ | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 114 | issue = 13 | pages = E2748–E2757 | date = March 2017 | pmid = 28289191 | pmc = 5380102 | doi = 10.1073/pnas.1620954114 | bibcode = 2017PNAS..114E2748A | doi-access = free }}{{cite journal | vauthors = Macleod T, Ainscough JS, Hesse C, Konzok S, Braun A, Buhl AL, Wenzel J, Bowyer P, Terao Y, Herrick S, Wittmann M, Stacey M | display-authors = 6 | title = The Proinflammatory Cytokine IL-36γ Is a Global Discriminator of Harmless Microbes and Invasive Pathogens within Epithelial Tissues | journal = Cell Reports | volume = 33 | issue = 11 | pages = 108515 | date = December 2020 | pmid = 33326792 | doi = 10.1016/j.celrep.2020.108515 | pmc = 7758160 | doi-access = free }}
