Summary: Enables glutamate dehydrogenase (NAD+) activity. Involved in glutamine metabolic process and tricarboxylic acid metabolic process. Acts upstream of or within positive regulation of insulin secretion. Located in mitochondrial matrix. Is expressed in several structures, including alimentary system; central nervous system; metanephros; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in familial hyperinsulinemic hypoglycemia 6; hyperinsulinism; and hypoglycemia. Orthologous to several human genes including GLUD1 (glutamate dehydrogenase 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
