26241911 Study of the expression of the GDH1/2 in human steroidogenic organs revealed that, while GDH2 was expressed specifically in steroid-synthesizing cells, GDH1 was expressed both in the cells that produce steroids and in those that lack endocrine function.
25225364 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.
24352816 hGDH2 can operate efficiently in the relatively acidic environment that prevails in astrocytes following glutamate uptake [review]
23874603 A stable-isotope labeling by amino acids in cell culture coupled with mass spectrometry-based proteomics identifies downregulation of glutamate dehydrogenase 2 (GLUD2) expression by HIV-1 Vpr in Vpr transduced macrophages
22709669 first N-terminal alpha helical structure is crucial for the mitochondrial import of hGDH2 and these findings may have implications in understanding the evolutionary mechanisms that led to the large mitochondrial targeting signals of human GDHs
22658952 first N-terminal alpha helical structure is crucial for the mitochondrial import of hGDH2 and these findings may have implications in understanding the evolutionary mechanisms that led to the large mitochondrial targeting signals of human GDHs
22360420 A protein encoded by this locus was found to be differentially expressed in postmortem brains from patients with atypical frontotemporal lobar degeneration.
21621574 Human GDH1 appears to act like bovine GDH1, but human GDH2 does not show the same enhancement of branched chain alpha-keto acid dehydrogenase complex enzyme activities.
21420458 [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.
20194501 GLUD2 glutamate dehydrogenase is expressed in neural and testicular supporting cells
19826450 A gain-of-function rare polymorphism in hGDH2 hastens the onset of Parkinson's disease in hemizygous subjects.
19826450 Observational study of gene-disease association. (HuGE Navigator)
19448744 Hence, while most of the hGDHs translocate into the mitochondria (a process associated with cleavage of the signal sequence), part of the protein localizes to the endoplasmic reticulum, probably serving additional functions
19428807 GDH2 localizes mainly to mitochondria and to a lesser extent to the endoplasmic reticulum of cells
19393024 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
19156168 Clinical trial of gene-disease association, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
18688271 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.
17924438 amino acid changes, acting in concert with Arg443Ser and Gly456Ala, ought to be responsible the unique properties of the brain-specific human isoenzyme
15750346 results suggest that cysteine 323 plays an important role in catalysis by human GDH isozymes; C323 is not directly involved in allosteric regulation.
15378063 GLUD2 originated by retroposition from GLUD1 in the hominoid ancestor less than 23 million years ago.
15044002 These results suggest that the Ser443 residue plays an important role in the different thermal stability of human glutamate dehydrogenase isozymes (hGDH1 and hGDH2).
