Part Of
This protein is part of 2 target(s):
| Target | Category | Definition |
|---|---|---|
| IkappaB kinase complex | cellular component | A trimeric protein complex that phosphorylates inhibitory-kappaB (I-kappaB) proteins. The complex is composed of two kinase subunits (alpha and beta) and a regulatory gamma subunit (also called NEMO). In a resting state, NF-kappaB dimers are bound to inhibitory IKB proteins, sequestering NF-kappaB in the cytoplasm. Phosphorylation of I-kappaB targets I-kappaB for ubiquitination and proteasomal degradation, thus releasing the NF-kappaB dimers, which can translocate to the nucleus to bind DNA and regulate transcription. [GOC:bf, GOC:ma, PMID:12055104, PMID:20300203] |
| CD40 receptor complex | cellular component | A protein complex that contains at least CD40 (a cell surface receptor of the tumour necrosis factor receptor (TNFR) superfamily), and other signaling molecules. [GOC:BHF, PMID:20614026, PMID:9221764] |
Involved In
This protein is involved in 32 target(s):
| Target | Category | Definition |
|---|---|---|
| skeletal muscle contraction | biological process | A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control. [GOC:mtg_cardio, GOC:mtg_muscle] |
| protein phosphorylation | biological process | The process of introducing a phosphate group on to a protein. [GOC:hb] |
| inflammatory response | biological process | The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages. [GO_REF:0000022, ISBN:0198506732] |
| immune response | biological process | Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. [GO_REF:0000022, GOC:add] |
| canonical NF-kappaB signal transduction | biological process | An intracellular signaling cassette characterized by the I-kappaB-kinase (IKK)-dependent activation of NF-kappaB, also known as the canonical NF-kappaB signaling cascade. The cascade begins with activation of a trimeric IKK complex (consisting of catalytic kinase subunits IKKalpha and/or IKKbeta, and the regulatory scaffold protein NEMO) and ends with the regulation of transcription of target genes by NF-kappaB. In a resting state, NF-kappaB dimers are bound to I-kappaB proteins, sequestering NF-kappaB in the cytoplasm. Phosphorylation of I-kappaB targets I-kappaB for ubiquitination and proteasomal degradation, thus releasing the NF-kappaB dimers, which can translocate to the nucleus to bind DNA and regulate transcription. The canonical NF-kappaB pathway is mainly stimulated by proinflammatory cytokines such as IL-1beta, tumor necrosis factor (TNF)-alpha, antigen ligands, and toll-like receptors (TLRs). [GOC:bf, PMID:12773372, PMID:34659217] |
| I-kappaB phosphorylation | biological process | The process of introducing a phosphate group into an inhibitor of kappa B (I-kappaB) protein. Phosphorylation of I-kappaB targets I-kappaB for ubiquitination and proteasomal degradation, thus releasing bound NF-kappaB dimers, which can translocate to the nucleus to bind DNA and regulate transcription. [GOC:bf, GOC:jl, PMID:21772278, PMID:7594468] |
| Rho protein signal transduction | biological process | An intracellular signaling cassette in which a small monomeric GTPase of the Rho subfamily relays a signal. [GOC:bf] |

[GOC:add, ISBN:0721601464] |
| positive regulation of interferon-alpha production | biological process | Any process that activates or increases the frequency, rate, or extent of interferon-alpha production. [GOC:mah, PMID:15546383] |

| tumor necrosis factor-mediated signaling pathway | biological process | The series of molecular signals initiated by tumor necrosis factor binding to its receptor on the surface of a cell, and ending with the regulation of a downstream cellular process, e.g. transcription. [GOC:mah, GOC:signaling] |

Reactive oxygen species include singlet oxygen, superoxide, and oxygen free radicals. [GOC:mah] |
| non-canonical NF-kappaB signal transduction | biological process | An intracellular signaling cassette characterized by the NIK-dependent processing and activation of NF-kappaB. Begins with activation of the NF-kappaB-inducing kinase (NIK), which in turn phosphorylates and activates IkappaB kinase alpha (IKKalpha).

The non-canonical NF-kappaB signaling pathway is generally activated by ligands of the TNF receptor superfamily, including lymphotoxin beta (LTB), CD40, OX40, RANK, TWEAK and B cell-activating factor (BAFF).
