Ikbkb Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
IκB Kinase Beta (IKKβ or IKBKB) is a serine/threonine protein kinase that plays a central role in the NF-κB signaling pathway. IKKβ catalyzes the phosphorylation of IκB proteins, leading to their degradation and subsequent activation of NF-κB transcription factors. [1]
IKBKB Protein is a protein involved in critical biological pathways relevant to neurodegenerative diseases. It plays important roles in neuronal function, cellular signaling, mitochondrial maintenance, or stress response mechanisms that are essential for neuronal health. [2]
Dysregulation or mutations in this protein contribute to the pathogenesis of Alzheimer's disease, Parkinson's disease, and related neurodegenerative disorders through effects on protein function, inflammatory signaling, mitochondrial function, or cell survival pathways. [3]

IKKβ is a 756 amino acid protein (approximately 87 kDa) that forms part of the IκB kinase (IKK) complex. The protein contains: [5]
The IKK complex consists of: [6]
IKKβ phosphorylates IκBα at Ser32 and Ser36, targeting it for ubiquitination and proteasomal degradation. This releases NF-κB dimers (p50/p65) to translocate to the nucleus. [7]
