**Background of NCF2 Recombinant Protein**
NCF2 (Neutrophil Cytosolic Factor 2), also known as p67phox, is a critical regulatory subunit of the NADPH oxidase complex, a key enzyme system responsible for generating reactive oxygen species (ROS) in phagocytic cells. This complex, composed of membrane-bound (e.g., CYBB/gp91phox and CYBA/p22phox) and cytosolic subunits (NCF1/p47phox, NCF2. NCF4/p40phox, and Rac GTPase), plays a central role in innate immunity by producing superoxide anions to eliminate pathogens. NCF2 specifically facilitates the assembly and activation of NADPH oxidase by interacting with other subunits and GTP-bound Rac, enabling electron transfer and ROS generation.
Mutations in the *NCF2* gene are linked to chronic granulomatous disease (CGD), a rare inherited immunodeficiency characterized by impaired microbial killing and recurrent infections. Studying NCF2’s structure-function relationships and its role in NADPH oxidase activation is essential for understanding CGD pathophysiology and developing targeted therapies.
Recombinant NCF2 protein, produced via bacterial or mammalian expression systems, enables researchers to investigate its molecular interactions, enzymatic regulation, and structural dynamics *in vitro*. It serves as a tool for screening small molecules or gene therapies aimed at restoring NADPH oxidase function in CGD patients. Additionally, recombinant NCF2 aids in studying ROS-related signaling pathways in inflammatory diseases, cancer, and autoimmune disorders, where dysregulated NADPH oxidase activity contributes to disease progression.
Recent advances in protein engineering and structural biology have further enhanced the production of bioactive NCF2 variants, supporting mechanistic studies and therapeutic development. By leveraging recombinant NCF2. researchers aim to unravel its role in immune regulation and oxidative stress, paving the way for novel interventions in immune deficiencies and inflammatory conditions.
