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.

Interaction
Homodimer. Interacts with MAVS/IPS1 (PubMed:16177806, PubMed:28011935, PubMed:27980081). Interacts (via protein kinase domain) with TTLL12 (via N-terminus); the interaction prevents MAVS binding to IKBKE (PubMed:28011935). Interacts with the adapter proteins AZI2/NAP1, TANK and TBKBP1/SINTBAD (PubMed:17568778). Interacts with SIKE1 (PubMed:16281057, PubMed:14560022). Interacts with TICAM1/TRIF, IRF3 and DDX58/RIG-I; interactions are disrupted by the interaction between IKBKE and SIKE1 (PubMed:14739303, PubMed:16281057, PubMed:23478265). Interacts with TOPORS; induced by DNA damage (PubMed:20188669). Interacts with CYLD (PubMed:18636086). Interacts (when polyubiquitinated) with IKBKB, IKBKG and MYD88 (PubMed:23453969). Interacts with IFIH1 (PubMed:17600090). Interacts with DDX3X; the interaction may be induced upon virus infection (PubMed:18636090, PubMed:20657822, PubMed:23478265, PubMed:27980081). Interacts with TRIM6 (via SPRY box) (PubMed:24882218). Interacts with unanchored K48-linked polyubiquitin chains; this leads to IKBKE activation (PubMed:24882218). Interacts with TBK1 (PubMed:29251827). Interacts with FKBP5 (PubMed:26101251, PubMed:31434731). (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.
