Mutations in human GLUD2 glutamate dehydrogenase affecting basal activity and regulation.

Abstract excerpt

Glutamate dehydrogenase (GDH) in human exists in GLUD1 and GLUD2 gene-encoded isoforms (hGDH1 and hGDH2, respectively), differing in their regulation and tissue expression pattern. Whereas hGDH1 is subject to GTP control, hGDH2 uses for its regulation, a novel molecular mechanism not requiring GTP. This is based on the ability of hGDH2 to maintain a baseline activity of <10% of its capacity subject to full...
