Regulatory subunit of the IKK core complex which 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. Its binding to scaffolding polyubiquitin seems to play a role in IKK activation by multiple signaling receptor pathways. However, the specific type of polyubiquitin recognized upon cell stimulation (either 'Lys-63'-linked or linear polyubiquitin) and its functional importance is reported conflictingly. Also considered to be a mediator for TAX activation of NF-kappa-B. Could be implicated in NF-kappa-B-mediated protection from cytokine toxicity. Essential for viral activation of IRF3. Involved in TLR3- and IFIH1-mediated antiviral innate response; this function requires 'Lys-27'-linked polyubiquitination.3 Publications

Ectodermal dysplasia and immunodeficiency 1 (EDAID1)9 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionA form of ectoderma dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. EDAID1 is an X-linked recessive disorder characterized by absence of sweat glands, sparse scalp hair, rare conical teeth and immunological abnormalities resulting in severe infectious diseases. Severely affected individuals may also show lymphedema, osteopetrosis, and, rarely, hematologic abnormalities. The phenotype is highly variable, and may be fatal in childhood.

Phosphorylation at Ser-68 attenuates aminoterminal homodimerization.1 Publication
Polyubiquitinated on Lys-285 through 'Lys-63'; the ubiquitination is mediated by NOD2 and RIPK2 and probably plays a role in signaling by facilitating interactions with ubiquitin domain-containing proteins and activates the NF-kappa-B pathway. Polyubiquitinated on Lys-399 through 'Lys-63'; the ubiquitination is mediated by BCL10, MALT1 and TRAF6 and probably plays a role in signaling by facilitating interactions with ubiquitin domain-containing proteins and activates the NF-kappa-B pathway. Monoubiquitinated on Lys-277 and Lys-309; promotes nuclear export. Polyubiquitinated through 'Lys-27' by TRIM23; involved in antiviral innate and inflammatory responses. Linear polyubiquitinated on Lys-111, Lys-143, Lys-226, Lys-246, Lys-264, Lys-277, Lys-285, Lys-292, Lys-302, Lys-309 and Lys-326; the head-to-tail polyubiquitination is mediated by the LUBAC complex and plays a key role in NF-kappa-B activation. Deubiquitinated by USP10 in a TANK-dependent and -independent manner, leading to the negative regulation of NF-kappa-B signaling upon DNA damage (PubMed:25861989).7 Publications
Sumoylated on Lys-277 and Lys-309 with SUMO1; the modification results in phosphorylation of Ser-85 by ATM leading to a replacement of the sumoylation by mono-ubiquitination on these residues.5 Publications
Neddylated by TRIM40, resulting in stabilization of NFKBIA and down-regulation of NF-kappa-B activity.1 Publication
(Microbial infection) Cleaved by hepatitis A virus (HAV) protease 3C allowing the virus to disrupt the host innate immune signaling.1 Publication
(Microbial infection) Polyubiquitinated on Lys-309 and Lys-321 via 'Lys-27'-linked ubiquitin by Shigella flexneri E3 ubiquitin-protein ligase ipah9.8, leading to its degradation by the proteasome.1 Publication

Homodimer; disulfide-linked.

Component of the I-kappa-B-kinase (IKK) core complex consisting of CHUK, IKBKB and IKBKG; probably four alpha/CHUK-beta/IKBKB dimers are associated with four gamma/IKBKG subunits. The IKK core complex seems to associate with regulatory or adapter proteins to form a IKK-signalosome holo-complex. The IKK complex associates with TERF2IP/RAP1, leading to promote IKK-mediated phosphorylation of RELA/p65.

Part of a complex composed of NCOA2, NCOA3, CHUK/IKKA, IKBKB, IKBKG and CREBBP.

Interacts with COPS3, CYLD, NALP2, TRPC4AP and PIDD1.

Interacts with ATM; the complex is exported from the nucleus.

Interacts with TRAF6.

Interacts with IKBKE.

Interacts with TANK; the interaction is enhanced by IKBKE and TBK1.

Part of a ternary complex consisting of TANK, IKBKB and IKBKG.

Interacts with ZFAND5.

Interacts with RIPK2.

Interacts with TNIP1 and TNFAIP3; TNIP1 facilitates the TNFAIP3-mediated de-ubiquitination of IKBKG.

Interacts with TNFAIP3; the interaction is induced by TNF stimulation and by polyubiquitin. Binds polyubiquitin; the interaction is mediated by two domains; reports about the binding to 'Lys-63'-linked and/or linear polyubiquitin, respective binding affinities and stoichiometry are conflicting.

Interacts with NLRP10.

Interacts with TANK; this interaction increases in response to DNA damage (PubMed:25861989).

Interacts with USP10; this interaction increases in response to DNA damage (PubMed:25861989).

Interacts with ZC3H12A; this interaction increases in response to DNA damage (PubMed:25861989).

Interacts with IFIT5; the interaction synergizes the recruitment of IKK to MAP3K7 and enhances IKK phosphorylation (PubMed:26334375).

Interacts with TRIM29; this interaction induces IKBKG/NEMO ubiquitination and proteolytic degradation (PubMed:27695001).

Interacts with TRIM13; this interaction leads to IKBKG/NEMO ubiquitination (PubMed:25152375).

Interacts with ARFIP2 (PubMed:26296658).

Interacts with RIPK1 (By similarity).

By similarity22 Publications

(Microbial infection) Interacts with Molluscum contagiosum virus protein MC005; this interaction inhibits NF-kappa-B activation.

1 Publication

(Microbial infection) Interacts with HTLV-1 Tax oncoprotein; the interaction activates IKBKG.

2 Publications

(Microbial infection) Interacts with Shigella flexneri ipah9.8; the interaction promotes TNIP1-dependent 'Lys-27'-linked polyubiquitination of IKBKG which perturbs NF-kappa-B activation during bacterial infection.
