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](/entities/nf-kb) signaling pathway. IKKβ catalyzes the phosphorylation of IκB proteins, leading to their degradation and subsequent activation of NF-κB transcription factors. [@supsup2008]

Overview
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. [@supsup2002]
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. [@supsup2006]

Structure
IKKβ is a 756 amino acid protein (approximately 87 kDa) that forms part of the IκB kinase (IKK) complex. The protein contains: [@supsup2015]
N-terminal kinase domain
Leucine zipper (LZ) for dimerization
Helix-loop-helix (HLH) domain
C-terminal NEMO-binding domain (NBD)
The IKK complex consists of: [@supsup2009]
IKKα (IKBK1)
IKKβ (IKBKB)
IKKγ/NEMO (IKBKG) - regulatory subunit
Molecular Function
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. [@supsup2011]
The study of Ikbkb Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
