Ikbkb Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
IKBKB (IκB Kinase Beta), also known as IKKβ, encodes the catalytic subunit of the IκB kinase (IKK) complex. The IKK complex, consisting of IKKα, IKKβ, and IKKγ (NEMO), is essential for activating the NF-κB transcription factor. IKKβ is the key kinase that phosphorylates IκBα and other IκB proteins, leading to their ubiquitination and degradation. This releases NF-κB to translocate to the nucleus and activate target genes. IKKβ is critical for immune responses, inflammation, cell survival, and is implicated in neurodegenerative diseases .

- Canonical pathway — Mediates classical NF-κB activation
- Signal integration — Receives from multiple receptors
- Complex formation — Requires NEMO for activity
IKBKB controls:
- IκB phosphorylation — S32/S36 on IκBα
- Signal transduction — From membrane to nucleus
- Inflammatory genes — Cytokines, chemokines
- Survival genes — Anti-apoptotic proteins
IKKβ regulates:
- TNF-α signaling — Primary pathway
- IL-1 signaling — Innate immunity
- TLR activation — Pattern recognition
- B cell function — Adaptive immunity
