IKK Gamma is a protein. This page describes its structure, normal nervous system function, role in neurodegenerative disease, and potential as a therapeutic target.
IKK Gamma (also known as NEMO - NF-kB Essential Modulator) is the regulatory subunit of the IKK (IkappaB kinase) complex. It serves as a scaffold and regulatory protein essential for NF-kB activation.
The protein contains:
N-terminal region: binds IKKα and IKKβ kinases
C-terminal region: contains coiled-coil domain and leucine zipper

The protein contains:
N-terminal region: binds IKKα and IKKβ kinases
C-terminal region: contains coiled-coil domain and leucine zipper
NEMO forms a heterotrimeric complex with IKKα and IKKβ catalytic subunits.
Normal Function in the Nervous System
IKK Gamma/NEMO is critical for NF-kB signaling in the nervous system:
NF-kB Activation: Essential for canonical NF-kB pathway activation in response to cytokines, stress, and pathogens
Neuronal Survival: NF-kB-mediated transcription promotes neuronal survival and plasticity
Synaptic Plasticity: NF-kB regulates AMPA receptor trafficking and synaptic strength
Neuroinflammation: Controls inflammatory gene expression in [microglia](/cell-types/microglia-neuroinflammation) and [astrocytes](/entities/astrocytes)
Myelination: NF-kB signaling regulates oligodendrocyte differentiation and myelination
Role in Neurodegeneration
IKK/NEMO signaling is dysregulated in several neurodegenerative diseases:
Alzheimer's Disease (AD)
Chronic neuroinflammation via NF-kB hyperactivation
Elevated IKK activity in AD brains
Pro-inflammatory cytokine production (IL-1β, TNF-α)
