    3. Data suggest that the change in tryptophan fluorescence of Y162W mutant of AAG (alkyladenine DNA glycosylase) is extremely rapid upon binding to either damaged or undamaged DNA, much faster than lesion-recognition and nucleotide flipping steps; thus, intercalation by tyrosine may be one of the earliest steps in search for/recognition of DNA damage. PMID: 28747435
    4. Rheumatoid arthritis is associated with a polymorphism in the MPG gene (rs2858056) and increased serum level of the MPG protein. PMID: 25757089
    5. Role of MPG protein in the DNA damage response through the base excision repair pathway PMID: 26025911
    6. results suggest that individuals carrying R120C and R141Q MPG variants may be at risk for genomic instability and associated diseases as a consequence. PMID: 25538240
    7. Elevated MPG activity is associated with lung cancer, possibly by creating an imbalance in the base excision repair pathway. PMID: 22266085
    8. In the case of alkyladenine DNA glycosylase, DNA intercalation contributes to the specific binding of a damaged nucleotide, but this enhanced specificity comes at the cost of reduced speed of nucleotide flipping. PMID: 25324304
    9. High MPG DNA repair assays for two different oxidative DNA lesions reveal associations with increased lung cancer risk. PMID: 25355292
    10. disease-stage-specific alterations in the expression of MPG may highlight a potential role for MPG in determining EAC onset and thus potentially be of clinical relevance for early disease detection and increased patient survival. PMID: 23137018
    11. AAG has a flexible amino terminus that tunes its affinity for nonspecific DNA, but we find that it is not required for intersegmental transfer. As AAG has only a single DNA binding site, this argues against the bridging model for intersegmental transfer PMID: 23839988
    12. AAG removes both methanol and 1,N(6)-ethenoadenine from DNA with single-turnover rate constants that are significantly greater than the corresponding uncatalyzed rates. PMID: 23688261

    16. N-methylpurine DNA glycosylase negatively regulates p53-mediated cell cycle arrest. PMID: 22801474
    17. AAG can make damaged DNA by catalyzing formation of an N-glycosyl bond between 1,N(6)-ethenoadenine (epsilonA) and abasic DNA. We attribute the reversibility of this reaction to the tight binding and slow subsequent hydrolysis of DNA containing an epsilonA lesion. PMID: 20873830
    18. Investigated the expression of MPG gene and protein in 128 glioma and 10 non-neoplastic brain tissues. Found MPG gene expression level in glioma tissues was significantly higher than that in non-neoplastic brain tissues (P < 0.001). PMID: 22496614
    19. The non-enzymatic binding of AAG to 3,N(4)-ethenocytosine specifically blocks ALKBH2-catalyzed repair of 3,N(4)-ethenocytosine but not that of methylated ALKBH2 substrates. PMID: 22079122
    20. Novel structures of AAG presented here help provide an understanding of this intriguing DNA repair protein, both in terms of understanding how AAG can recognize different types of DNA damage and in terms of how it may search the genome for DNA damage. PMID: 22148158
    21. Evaluation of APNG protein levels in several clinical datasets demonstrated that in patients, high nuclear APNG expression correlated with poorer overall survival compared with patients lacking APNG expression. PMID: 22156195

    26. AAG uses hopping to effectively search both strands of a DNA duplex in a single binding encounter. PMID: 20201599
    27. The human alkyl-N-purine-DNA glycosylase (ANPG or MPG) excises both 1,N(6)-ethenoadenine and 1,N(2)-ethenoguanine adducts, exocyclic DNA adducts generated by lipid peroxidation, when present in DNA. PMID: 12016206
    28. The human alkyl-N-purine-DNA glycosylase (ANPG or MPG) excises with high efficiency hypoxanthine residues, deamination product of adenine, when present in DNA. ANPG is by far the most efficient hypoxanthine-DNA glycosylase of all the enzymes tested. PMID: 8016081
    29. The human alkyl-N-purine-DNA glycosylase (ANPG or MPG) binds tightly to ethenocytosine adduct when present in DNA. Unlike the ethenopurines, ANPG does not excise ethenocytosine but prevents its repair by forming an abortive protein-DNA complex. PMID: 14761949
    30. AAG and its mutants bind DNA containing one and two base-pair loops with significant affinity, thus shielding them from mismatch repair; the strength of such binding correlates with their ability to induce the mutator phenotype. PMID: 20347426
    31. evidence that the excised base rather than AP-site could be rate-limiting for DNA-glycosylase reactions PMID: 19616486
    32. Effects of hydrogen bonding within a damaged base pair on the activity of wild type and DNA-intercalating mutants of the human alkyladenine DNA glycosylase. PMID: 12077143

    42. Although the amino terminus of the protein is dispensable for glycosylase activity at a single site, we find that deletion of the 80 amino-terminal amino acids significantly decreases the processivity of AAG. PMID: 18839966
    43. Results suggest the possible significance of repair of the frequent lesions in single-stranded DNA transiently generated during replication and transcription. PMID: 19219989
    44. RNS-induced posttranslational modification of AAG is one mechanism of base excision repair dysregulation PMID: 19864471
