• Post Translational Modifications: Autophosphorylated and phosphorylated by IKBKB/IKKB. Phosphorylation at Ser-172 is enhanced by the interaction with DDX3X. Phosphorylated at Thr-501 upon IFN activation. Sumoylation by TOPORS upon DNA damage is required for protection of cells against DNA damage-induced cell death. Desumoylated by SENP1.'Lys-63'-linked polyubiquitinated at Lys-30 and Lys-401 by TRAF2:BIRC2 and TRAF2:BIRC3 complexes. Ubiquitination is induced by LPS, TNFA and interleukin-1 and required for full kinase activity and KF-kappa-B pathway activation.
• Subunit Structure: Homodimer. Interacts with MAVS/IPS1. Interacts (via protein kinase domain) with TTLL12 (via N-terminus); the interaction prevents MAVS binding to IKBKE. Interacts with the adapter proteins AZI2/NAP1, TANK and TBKBP1/SINTBAD. Interacts with SIKE1. Interacts with TICAM1/TRIF, IRF3 and DDX58/RIG-I; interactions are disrupted by the interaction between IKBKE and SIKE1. Interacts with TOPORS; induced by DNA damage. Interacts with CYLD. Interacts (when polyubiquitinated) with IKBKB, IKBKG and MYD88. Interacts with IFIH1. Interacts with DDX3X; the interaction is found to be induced upon virus infection. Interacts with TRIM6 (via SPRY box). Interacts with unanchored K48-linked polyubiquitin chains; this leads to IKBKE activation. Interacts with TBK1. (Microbial infection) Interacts (via Protein kinase domain) with arenavirus protein N; the interaction inhibits IKBKE kinase function. (Microbial infection) Interacts with Ebola virus protein VP35; the interaction leads to inhibition of cellular antiviral response by blocking necessary interactions between the IKBKE and MAVS/IPS as well as its substrates IRF3 and IRF7. (Microbial infection) Interacts with human T-cell leukemia virus 1/HTLV-1 protein HBZ.
• Similarity: Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. I-kappa-B kinase subfamily.
• Subcellular Location: Cytoplasm. Nucleus. Nucleus>PML body.; Note: Targeting to PML nuclear bodies upon DNA damage is TOPORS-dependent (PubMed:20188669). Located diffusely throughout the cytoplasm but locates to punctate cytoplasmic bodies when coexpressed with TRIM6 (PubMed:24882218).
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Western Blot (WB)

(Western blot analysis IKK-ε (Phospho-Ser172) using Na3VO4 treated HepG2 whole cell lysates.-/+ means absence or presence of N peptide（non-phospho peptide) and P peptide(phospho peptide).)

Immunohistochemistry (IHC)

(Staining Rat kidney tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary antibody.)

Serine/threonine kinase that plays an essential role in regulating inflammatory responses to viral infection, through the activation of the type I IFN, NF-kappa-B and STAT signaling. Also involved in TNFA and inflammatory cytokines, like Interleukin-1, signaling. Following activation of viral RNA sensors, such as RIG-I-like receptors, associates with DDX3X and phosphorylates interferon regulatory factors (IRFs), IRF3 and IRF7, as well as DDX3X. This activity allows subsequent homodimerization and nuclear translocation of the IRF3 leading to transcriptional activation of pro-inflammatory and antiviral genes including IFNB. In order to establish such an antiviral state, IKBKE forms several different complexes whose composition depends on the type of cell and cellular stimuli. Thus, several scaffolding molecules including IPS1/MAVS, TANK, AZI2/NAP1 or TBKBP1/SINTBAD can be recruited to the IKBKE-containing-complexes. Activated by polyubiquitination in response to TNFA and interleukin-1, regulates the NF-kappa-B signaling pathway through, at least, the phosphorylation of CYLD. Phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. In addition, is also required for the induction of a subset of ISGs which displays antiviral activity, may be through the phosphorylation of STAT1 at 'Ser-708'. Phosphorylation of STAT1 at 'Ser-708' seems also to promote the assembly and DNA binding of ISGF3 (STAT1:STAT2:IRF9) complexes compared to GAF (STAT1:STAT1) complexes, in this way regulating the balance between type I and type II IFN responses. Protects cells against DNA damage-induced cell death. Also plays an important role in energy balance regulation by sustaining a state of chronic, low-grade inflammation in obesity, wich leads to a negative impact on insulin sensitivity. Phosphorylates AKT1.

NCBI Description

IKBKE is a noncanonical I-kappa-B (see MIM 164008) kinase (IKK) that is essential for regulating antiviral signaling pathways. IKBKE has also been identified as a breast cancer (MIM 114480) oncogene and is amplified and overexpressed in over 30% of breast carcinomas and breast cancer cell lines (Hutti et al., 2009 [PubMed 19481526]).[supplied by OMIM, Oct 2009]

Uniprot Description

IKKE: a oncogenic kinase of the IKK family. Phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. Plays a pivotal role in coordinating the activation of IRF3 and NF-kappaB in the innate immune response. Its redistribution to PML nuclear bodies upon DNA damage is TOPORS-dependent. Is a breast cancer oncogene that exerts its oncogenic properties through cRel.
