靶點詳情

  • 功能：
    Catalyzes the three sequential steps of the methylation pathway of phosphatidylcholine biosynthesis, the SAM-dependent methylation of phosphatidylethanolamine (PE) to phosphatidylmonomethylethanolamine (PMME), PMME to phosphatidyldimethylethanolamine (PDME), and PDME to phosphatidylcholine (PC).
  • 基因功能參考文獻：
    1. Study found three gene variants (CLOCK-rs4864548, PEMT-rs936108, and GHRELIN-rs696217) that exhibited uncorrected gene-by-sleep duration interactions in relation to BMI z-scores in a cohort of New Zealand European children. However, no interactions were identified in percentage body fat differences. Notably, these interactions are evident without detectable effects on sleep duration. PMID: 28899534
    2. In genotypic combination analysis considering PEMT -744GG/CHDH +432GG/BHMT +742GG as the reference combination, PEMT -744GC/CHDH +432GG/BHMT +742GG genotypic combination was significantly higher in mothers of a down syndrome child compared with that in control mothers with an odds ratio of 2.061 (95% CI: 1.10-3.86, P=0.0342). PMID: 27677362
    3. Results showed that PEMT mRNA expression in liver tissues of non-alcoholic steatohepatitis (NASH) patients was significantly lower than those with simple steatosis suggesting a distinct clinical entity of lean NASH with insufficiency of PEMT activities. PMID: 26883167
    4. a significant association between the PEMT rs7946 A-allele and a risk of nonalcoholic fatty liver disease, with the effect being more prominent in East-Asians, but not in non-Asians (Meta-Analysis) PMID: 26636496
    5. Data show that phosphatidylethanolamineN-methyltransferase (PEMT) rs12325817 polymorphism only marginally changed the association value with academic achievement. PMID: 26728177
    6. Data suggest that maternal dietary intake during lactation (here, choline intake exceeding dietary recommendations) can alter hepatic PEMT activity and increase choline content of breast milk. PMID: 26025328
    7. MTHFR rs1801131 C allele and PEMT rs4646356 T allele were associated with a high risk of type 2 diabetes in Han Chinese. PMID: 25074646
    8. The GG genotype of the PEMT G774C polymorphism, higher levels of serum homocysteine and lower levels of serum betaine are associated with an increased risk of microangiopathy in patients with diabetes. PMID: 23794489
    9. PEMT is a functional single nucleotide polymorphism (rs7946) in PEMT with sporadic Alzheimer's disease risk in a Han Chinese population. PMID: 21881829
    10. the PEMT -774G>C and CHDH +432G>T polymorphisms were associated with sperm concentration. This finding suggests a possible influence of these genes on sperm quality PMID: 22387881
    11. genetic association studies on endometriosis in a population of women in Poland: Data suggest interaction between an SNP in PEMT (rs4244593) and an SNP in MTHFR (Ala222Val; rs1801133) in infertile women with some indication of endometriosis. PMID: 21429654
    12. nvestigation of factors affecting liver PEMT activity: PEMT activity is lower in liver samples from women who are homozygous for an SNP in PEMT (rs12325817) PMID: 21411618
    13. allele-specific ablation of estrogen receptor-DNA interaction in the PEMT locus prevents hormone-inducible PEMT expression, conferring risk of choline deficiency in women PMID: 21059658
    14. Choline requirements for both women are increased by the genetic polymorphism rs12325817 in phosphatidylethanolamine-N-methyltransferase. PMID: 20861172
    15. Total intake of choline and genotype can influence the concentrations of choline and its metabolites in the breast milk and blood of lactating women and thereby affect the amount of choline available to the developing infant. PMID: 20534746
    16. The allele frequency of PEMT did not show a significant difference between normal control group and fatty liver patients (P=0.222). PMID: 19262398
    17. an examination of the membrane topography of this enzyme PMID: 12431977
    18. PEMT2 mRNA expression was inversely related to tumor proliferation and to histologic grade. PMID: 12931022
    19. PEMT-mediated Hcy secretion correlated with the methyltransferase activity of the enzyme, independently of subcellular localization PMID: 15927961
    20. Val175Met variant of PEMT could be a susceptibility candidate to nonalcoholic steatohepatitis (NASH), because it is more frequently observed in NASH patients and non-obese persons with Val175Met variant of PEMT are facilitated to develop NASH PMID: 17391797
    21. Human PEMT genes have three unique transcription start sites, which are indicative of either multiple promoters and/or alternative splicing. PMID: 17456783
    22. The present results suggest that the PEMT gene may contribute to the etiology of schizophrenia. PMID: 17720317
    23. single nucleotide polymorphisms of choline-metabolizing genes, PEMT -774G>C (rs12325817) and CHDH +432G>T (rs12676), were found be related to breast cancer risk PMID: 18230680
    24. These data suggest that polymorphisms in PEMT genes relevant to choline metabolism modulate parameters of choline status when folate intake is restricted. PMID: 19167960
    25. in folate-deplete men, several factors with roles in 1-carbon metabolism interact with the MTHFR C677T genotype to affect plasma homocysteine PMID: 19211833
    26. No association of the rs4646396 SNP in the PEMT locus with schizophrenia in a Chinese case-control sample. PMID: 19647326
