Overview

NCF2 (Neutrophil Cytosolic Factor 2), also known as p67phox, is a key component of the NADPH oxidase complex that generates superoxide anions in phagocytic cells. While primarily studied in immune cells, NCF2 and the NADPH oxidase system are increasingly recognized as important contributors to oxidative stress in neurodegenerative diseases, particularly in [microglia](/cell-types/microglia-neuroinflammation)-mediated neuroinflammation.

Function

NCF2 encodes the p67phox subunit of the NADPH oxidase complex. This multi-subunit enzyme complex is responsible for the production of [reactive oxygen species](/entities/reactive-oxygen-species) (ROS) through the one-electron reduction of oxygen.

NADPH Oxidase Complex

The NADPH oxidase complex consists of:

• Membrane components: CYBB (gp91phox) and CYBA (p22phox) - form the cytochrome b558
• Cytosolic components: NCF1 (p47phox), NCF2 (p67phox), NCF4 (p40phox), and RAC2

• Assembly of the active oxidase complex: Translocates to the membrane upon cell activation
• Interaction with RAC-GTP: Brings RAC to the membrane complex
• Sustained ROS production: Essential for optimal oxidase activity

Disease Associations

Alzheimer's Disease

Microglial NADPH oxidase is chronically activated in Alzheimer's disease brain, contributing to oxidative stress and neuroinflammation. NCF2 expression is upregulated in microglia surrounding amyloid plaques, and NADPH oxidase-derived ROS may accelerate amyloid pathology and neuronal damage.

Parkinson's Disease

NADPH oxidase plays a key role in microglial activation and dopaminergic neuron vulnerability in PD. Studies show increased NCF2 expression in activated microglia in PD brain and animal models. Inhibition of NADPH oxidase is protective in PD models.

Chronic Granulomatous Disease

Mutations in NCF2 cause autosomal recessive chronic granulomatous disease (CGD), characterized by defects in phagocyte oxidative burst and recurrent infections.

Expression

NCF2 is primarily expressed in neutrophils, monocytes, and microglia. In the brain, NCF2 is expressed in microglia, particularly in regions associated with neurodegenerative pathology. Expression is low in resting microglia but increases dramatically upon activation.
