Background: Interferon regulatory factors (IRFs) comprise a family of transcription factors that function within the Jak/Stat pathway to regulate interferon (IFN) and IFN-inducible gene expression in response to viral infection (1). IRFs play an important role in pathogen defense, autoimmunity, lymphocyte development, cell growth, and susceptibility to transformation. The IRF family includes nine members: IRF-1, IRF-2, IRF-9/ISGF3γ, IRF-3, IRF-4 (Pip/LSIRF/ICSAT), IRF-5, IRF-6, IRF-7, and IRF-8/ICSBP. All IRF proteins share homology in their amino-terminal DNA-binding domains. IRF family members regulate transcription through interactions with proteins that share similar DNA-binding motifs, such as IFN-stimulated response elements (ISRE), IFN consensus sequences (ICS), and IFN regulatory elements (IRF-E) (2).

Background: IRG1 (Immune-responsive gene 1) is one of the most up-regulated genes in macrophages under proinflammatory conditions (1). It is also highly expressed in the pregnant uterus during implantation (2,3). IRG1 is a cis-aconitate decarboxylase that produces itaconic acid by decarboxylating cis-aconic acid, an intermediate of the tricarboxylic acid cycle (4). Itaconic acid is an endogenous inhibitor of succinate dehydrogenase, linking macrophage metabolic rewiring and regulation of inflammation (5,6).

Background: Iron regulatory proteins (IRPs; also known as IREBs) are RNA-binding proteins that recognize iron-responsive elements (IREs) and play an important role in maintaining iron homeostasis in mammalian cells. IREs are conserved cis-regulatory hairpin structures located within the 5’ or 3’ untranslated regions (UTRs) of target mRNAs. IRPs inhibit translation when bound to IREs within the 5’ UTR of mRNA encoding for proteins involved in iron storage, export, and utilization. IRP binding to multiple IREs within the 3’ UTR of transferin receptor 1 (TFR1) mRNA prevents its degradation, thereby augmenting translation of TFR1 and increasing iron uptake into cells (1-3). Dysregulation of IRPs has been associated with human cancers (4-6).

Background: Insulin receptor substrate 1 (IRS-1) is one of the major substrates of the insulin receptor kinase (1). IRS-1 contains multiple tyrosine phosphorylation motifs that serve as docking sites for SH2-domain containing proteins that mediate the metabolic and growth-promoting functions of insulin (2-4). IRS-1 also contains over 30 potential serine/threonine phosphorylation sites. Ser307 of IRS-1 is phosphorylated by JNK (5) and IKK (6) while Ser789 is phosphorylated by SIK-2, a member of the AMPK family (7). The PKC and mTOR pathways mediate phosphorylation of IRS-1 at Ser612 and Ser636/639, respectively (8,9). Phosphorylation of IRS-1 at Ser1101 is mediated by PKCθ and results in an inhibition of insulin signaling in the cell, suggesting a potential mechanism for insulin resistance in some models of obesity (10).

Background: Interferon-stimulated 15 kDa protein (ISG15), also known as ubiquitin cross-reactive protein (UCRP), is a member of the ubiquitin-like protein family and functions in various biological pathways from pregnancy to innate immune responses (1). Expression of ISG15 is stimulated by cellular exposure to type 1 interferons α and β, in addition to infection with viruses such as influenza B (2,3). After exposure to type I interferons, both lymphocytes and monocytes, in addition to some fibroblasts and epithelial cells, release ISG15 into culture medium (1,4). ISG15 has been shown to function as a cytokine, stimulating interferon γ secretion by monocytes and macrophages, proliferation of natural killer cells, and chemotactic responses in neutrophils (4,5). ISG15 has also been shown to function intracellularly, being covalently conjugated to other proteins by E1 (Ube1L), E2 (UbcH8) and E3 ligases via a multi-step process analogous to ubiquitination (6,7). ISG15 is removed from proteins by the ubiquitin processing protease Ubp43 (8). ISG15-protein conjugation (ISGylation) is induced by type 1 interferons, and target proteins include the serine protease inhibitor Serpin 2A, PLCγ1, ERK1/2, Jak1 and Stat1 (9,10). Unlike ubiquitination, ISGylation does not target proteins for degradation, rather ISGylation increases Jak1 and Stat1 activity, enhancing the cellular response to interferons (11).

Background: ITCH is a HECT domain-containing E3 ubiquitin ligase, first identified in genetic studies of the mouse agouti locus, in which mutations result in characteristic coat color changes. One particular agouti mutation (non-agouti-lethal 18H) is notable for the development of immunological defects not observed in other agouti mutant mice; these include lymphoid hyperplasia and chronic stomach, lung and skin inflammation (manifest as constant itching). The 18H agouti mutation was traced to a chromosomal inversion that disrupted expression of an adjacent gene in the agouti locus, subsequently termed Itch to reflect the chronic itching phenotype (1-3).Further characterizations revealed that Itch encoded a NEDD4-like E3-ubiquitin ligase capable of catalyzing Lys29, Lys48, and/or Lys63-linked ubiquitination of target proteins, leading to their degradation by the proteosome pathway (4-6). The distinct phenotypes of Itch mutant mice led to the identification of an important regulatory role for ITCH-mediated ubiquitination in inflammatory signaling pathways. For example, ITCH-mediated ubiquitination of the transcription factor JunB was shown to play a direct inhibitory role in regulating expression of the proinflammatory cytokine IL-4. ITCH-null T lymphocytes consequently exhibit increased production of IL-4, leading to biased differentiation of naive CD4+ cells towards the proinflammatory Th2 lineage (7). In accordance with the findings from mutant Itch mouse models, a genetic linkage study in humans identified loss-of-function mutations in ITCH as a direct cause of syndromic multisystem autoimmune disease (SMAD) (8).Notably, targets of ITCH-mediated ubiquitination are not restricted to immune signaling pathways. For example, key mediators of the Hedgehog (9,10), Wnt/β-catenin (11), Hippo (12), and Notch signaling pathways (13,14) have been identified as important targets of ITCH-mediated ubiquitination (2).

Background: Interleukin-2 inducible T-cell kinase (Itk, Emt or Tsk) is a member of the non-receptor protein tyrosine kinases. Family members of Itk include Tec, Btk, Rlk and Bmx and are all defined by a common structure: an amino-terminal PH domain, a Tec-homology domain and a SH3 and SH2 domain followed by a carboxy-terminal kinase domain (1). Tec, Rlk and Itk are expressed in T cells and activated in response to T cell receptor (TCR) engagement. Data demonstrate that Itk functions in signal transduction downstream of TCR and activates PLCgamma1 and Erk. Lck directly activates Itk through phosphorylation in the conserved activation loop at Tyr511, and furthermore, Itk is autophosphorylated in the SH3 domain at Tyr180. Itk-Y180F is still capable of phosphorylating PLCgamma1 in contrast to Itk-Y511F, which has lost that function (2-3). Itk -/- mice show reduced lung inflammation, eosinophil infiltration and mucous production in response to allergic asthma induction. Thus, Itk could become a desirable target for anti-asthmatic treatments (4).
