Important for recycling the chief excitatory neurotransmitter, glutamate, during neurotransmission.
基因功能參考文獻:
hGDH2 evolution bestowed large human neurons with enhanced glutamate metabolizing capacity, thus strengthening cortical excitatory transmission. PMID: 26399640
This study demonstrated that hGDH2 expression increases capacity for uptake and oxidative metabolism of glutamate, particularly during increased workload and hypoglycemia. PMID: 28032919
This proliferation requires glutamate dehydrogenase 2, which synthesizes glutamate from ammonia and alpha-ketoglutarate and is expressed in MCF7 and T47D cells. Our findings provide insight into how cancer cells survive under glutamine deprivation conditions and thus contribute to elucidating the mechanisms of tumor growth. PMID: 29146184
The expression of GLUD2 was identified in the cellular and subcellular compartments of numerous tissues. PMID: 27422263
Notably, the introduction of GLUD2 did not affect glutamate levels in mice, consistent with observations in the primates. Instead, the metabolic effects of GLUD2 center on the tricarboxylic acid cycle, suggesting that GLUD2 affects carbon flux during early brain development, possibly supporting lipid biosynthesis. PMID: 27118840
IDH1(R132H) exhibits a growth-inhibitory effect that is abrogated in the presence of glutamate dehydrogenase 2 (GLUD2), a hominoid-specific enzyme purportedly optimized to facilitate glutamate turnover in human forebrain. PMID: 25225364
hGDH2 can operate efficiently in the relatively acidic environment that prevails in astrocytes following glutamate uptake [review] PMID: 24352816
[review] Whereas GDH2 in most mammals is encoded by a single functional GLUD1 gene expressed widely, humans have acquired through retroposition an X-linked GLUD2 gene that encodes a highly homologous isoenzyme GDH2 expressed in testis and brain. PMID: 21420458
GLUD2 glutamate dehydrogenase is expressed in neural and testicular supporting cells PMID: 20194501
A gain-of-function rare polymorphism in hGDH2 hastens the onset of Parkinson's disease in hemizygous subjects. PMID: 19826450
amino acid changes, acting in concert with Arg443Ser and Gly456Ala, ought to be responsible the unique properties of the brain-specific human isoenzyme PMID: 17924438
Mitochondrial targeting specificity of GLUD2 is due to an amino acid substitution in the mitochondrial targeting sequence soon after the duplication event in the hominoid ancestor approximately 18-25 million years ago. PMID: 18688271
study of molecular mechanisms regulating hGDH2 function by creating & analyzing mutants with single amino acid substitutions in the regulatory domain (antenna, pivot helix) of the protein PMID: 19393024
GDH2 localizes mainly to mitochondria and to a lesser extent to the endoplasmic reticulum of cells PMID: 19428807
