models of infection and inflammation.";
Nat. Commun. 10:1729-1729(2019).
-!- FUNCTION: Serine kinase that plays an essential role in the NF-kappa-B
signaling pathway which is activated by multiple stimuli such as
inflammatory cytokines, bacterial or viral products, DNA damages or
other cellular stresses. Acts as part of the canonical IKK complex in
the conventional pathway of NF-kappa-B activation and phosphorylates
inhibitors of NF-kappa-B on serine residues. These modifications allow
polyubiquitination of the inhibitors and subsequent degradation by the
proteasome. In turn, free NF-kappa-B is translocated into the nucleus
and activates the transcription of hundreds of genes involved in immune
response, growth control, or protection against apoptosis. Negatively
regulates the pathway by phosphorylating the scaffold protein TAXBP1
and thus promoting the assembly of the A20/TNFAIP3 ubiquitin-editing
complex (composed of A20/TNFAIP3, TAX1BP1, and the E3 ligases ITCH and
RNF11). Therefore, CHUK plays a key role in the negative feedback of
NF-kappa-B canonical signaling to limit inflammatory gene activation.
As part of the non-canonical pathway of NF-kappa-B activation, the
MAP3K14-activated CHUK/IKKA homodimer phosphorylates NFKB2/p100
associated with RelB, inducing its proteolytic processing to NFKB2/p52
and the formation of NF-kappa-B RelB-p52 complexes. In turn, these
complexes regulate genes encoding molecules involved in B-cell survival
and lymphoid organogenesis. Participates also in the negative feedback
of the non-canonical NF-kappa-B signaling pathway by phosphorylating
and destabilizing MAP3K14/NIK. Within the nucleus, phosphorylates
CREBBP and consequently increases both its transcriptional and histone
acetyltransferase activities. Modulates chromatin accessibility at NF-
kappa-B-responsive promoters by phosphorylating histones H3 at 'Ser-10'
that are subsequently acetylated at 'Lys-14' by CREBBP. Additionally,
phosphorylates the CREBBP-interacting protein NCOA3. Also
phosphorylates FOXO3 and may regulate this pro-apoptotic transcription
factor. Phosphorylates RIPK1 at 'Ser-25' which represses its kinase
activity and consequently prevents TNF-mediated RIPK1-dependent cell
death (PubMed:30988283). {ECO:0000250|UniProtKB:O15111,

-!- ACTIVITY REGULATION: Activated when phosphorylated and inactivated when
dephosphorylated.
-!- SUBUNIT: 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 (PubMed:10195894). The IKK
complex associates with TERF2IP/RAP1, leading to promote IKK-mediated
phosphorylation of RELA/p65 (PubMed:20622870). Part of a complex
composed of NCOA2, NCOA3, CHUK/IKKA, IKBKB, IKBKG and CREBBP. Part of a
70-90 kDa complex at least consisting of CHUK/IKKA, IKBKB, NFKBIA,
RELA, ELP1 and MAP3K14 (By similarity). Directly interacts with TRPC4AP
(PubMed:14585990). May interact with TRAF2. Interacts with NALP2. May
interact with MAVS/IPS1 (By similarity). Interacts with ARRB1 and ARRB2
(PubMed:18194271). Interacts with NLRC5; prevents CHUK phosphorylation
and kinase activity. Interacts with PIAS1; this interaction induces
PIAS1 phosphorylation. Interacts with ZNF268 isoform 2; the interaction
is further increased in a TNF-alpha-dependent manner (By similarity).
Interacts with LRRC14 (By similarity). Interacts with SASH1 (By
similarity). Directly interacts with DDX3X after the physiological
activation of the TLR7 and TLR8 pathways; this interaction enhances
CHUK autophosphorylation (By similarity).
