Validated All-in-One™ qPCR Primer for G6PC1(NM_000151.3) Search again
By default, qPCR primer pairs are designed to measure the expression level of the splice variant (accession number) you selected for this gene WITHOUT consideration of other possible variants of this gene. If this gene has multiple variants, and you would like to measure the expression levels of one particular variant, multiple variants, or all variants, please contact us for a custom service project at inquiry@genecopoeia.com.

Summary
Glucose-6-phosphatase is an integral membrane protein of the endoplasmic reticulum that catalyzes the hydrolysis of D-glucose 6-phosphate to D-glucose and orthophosphate. It is a key enzyme in glucose homeostasis, functioning in gluconeogenesis and glycogenolysis. Defects in the enzyme cause glycogen storage disease type I (von Gierke disease). [provided by RefSeq].
Gene References into function
- we report the results of structure and function studies of the 48 missense mutations and the DeltaF327 codon deletion mutation, grouped as active site, helical, and nonhelical mutations
- active site of G6Pase: role of HIS176 as the nucleophile forming the phosphohistidine-enzyme intermediate during catalysis
- homozygosity for one G6PC mutation, G188R, seems to be associated with a glycogen storage disease type I non-a phenotype and homozygosity for the 727G>T mutation may be associated with a milder phenotype but an increased risk for hepatocellular carcinoma
- The amino-terminal domain of G6PT is required for optimal glucose-6-phosphate uptake activity.
- maximum repression of basal glucose-6-phosphatase catalytic subunit (G6Pase) gene transcription by insulin requires two distinct promoter regions, designated that together form an insulin response unit.
- Five mutants lack microsomal G6P uptake activity and one retains residual activity, suggesting that in G6PT the signature motif is a functional element required for microsomal glucose-6-phosphate transport.
- a novel, widely expressed G6Pase-related protein, PAP2.8/UGRP, renamed here G6Pase-beta couples with the G6P transporter to form an active G6Pase complex that can hydrolyze G6P to glucose
- Glc-6-Pase-alpha and Glc-6-Pase-beta share a similar active site structure, topology, and mechanism of action
- G6pc expression was functionally silenced by adenovirus-mediated delivery of short hairpin RNA.
- Findings suggest that the screening for 727G-->T and R83H mutations of glucose-6-phosphatase gene in conjunction with the 1176 polymorphism linkage analysis is a good method for gene and prenatal diagnosis of glycogen storage disease Ia.
- HNF4alpha, CREM, HNF1alpha, and C/EBPalpha have roles in transcriptional regulation of the glucose-6-phosphatase gene by cAMP/vasoactive intestinal peptide in the intestine
- G6PC1 hepatic activity was abnormally low in 98 SIDS (preterm, n=13; term, n=85), and non-SIDS preterm infants (n=35) compared to term non-SIDS infants (n=29) and adults (n=9)
- analysis of mutation spectrum of glycogen storage disease type Ia in Tunisia
- summary of the reported G6PC mutations and review what mutagenesis studies have revealed about the structure and function of the G6PC catalytic unit [review]
- HNF-4 and Foxo1 are required for reciprocal transcriptional regulation of glucokinase and glucose-6-phosphatase genes in response to fasting and feeding
- EGF also inhibits hepatic G6Pase gene expression in vivo
