Mouse neuroglobin showing the heme and complexed with sulfate and Xe 3gk9 Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Neuroglobin (NGB) is involved in cellular oxygen homeostasis. It binds oxygen reversibly. It increases oxygen availability in the brain. It is a monomer containing a heme group[1]. Relevance NGB may influence the course of Alzhheimer's disease[2].
