MGR1 is a probe that generates reactive oxygen species (ROS).1 Upon activation by esterases, MGR1 produces superoxide in vitro, an effect that is reversed by superoxide dismutase (SOD). MGR1 produces ROS and increases production of oxidized phosphatidylserine species in HEK293T cells. It reduces viability of HEK293T cells (IC50s = 5.1-6.3 μM).

MGr1-Ag is associated with multidrug-resistant phenotype of gastric cancer cells
Gastric Cancer 2002;5(3):154-9.PMID:12378342DOI:10.1007/s101200200027.
Background: MGr1-antigen (Ag) was previously reported as an upregulated protein in multidrug-resistant (MDR) gastric cancer cells. The aim of this study was to characterize the role of MGr1-Ag in the multidrug resistance of gastric cancer cells. Methods: Laser scanning confocal microscopy (LSCM), two-dimensional electrophoresis, and Western blot were used to detect MGr1-Ag in gastric cancer cells. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay was used to determine the sensitivity of the MDR gastric cancer cells, SGC7901/VCR, to chemotherapeutic drugs. Adriamycin accumulation and retention in SGC7901/VCR cells were analyzed using flow cytometry. Results: LSCM showed that MGr1-Ag localized mainly on the membrane and partly in the cytoplasm of SGC7901/VCR cells. Western blot showed that the expression level of MGr1-Ag in SGC7901/VCR cells was higher than that in its parental cells, SGC7901, and that the apparent molecular weight and isoelectric point of MGr1-Ag were 42 kDa and pH 4.8, respectively. After incubation with MGR1 antibody, SGC7901/VCR cells showed significantly decreased IC(50) values for adriamycin (from 0.887 +/- 0.081 mg/l to 0.607 +/- 0.084 mg/l; P, 0.05), vincristine (from 0.707 +/- 0.055 mg/l to 0.557 +/- 0.042 mg/l; P, 0.05), and 5-fluorouracil (from 4.367 +/- 0.407 mg/l to 2.630 +/- 0.644 mg/l; P, 0.05), as well as slightly increased IC(50) values for mitomycin (from 0.183 +/- 0.045 mg/l to 0.198 +/- 0.048 mg/l; P. 0.05). In addition, incubation with MGR1 significantly enhanced adriamycin accumulation and retention in SGC7901/VCR cells. Conclusion: Overexpression of MGr1-Ag is associated with the MDR phenotype of gastric cancer cells.
De novo genome sequencing of mycoparasite Mycogone perniciosa strain MGR1 sheds new light on its biological complexity
Braz J Microbiol 2021 Sep;52(3):1545-1556.PMID:34138459DOI:10.1007/s42770-021-00535-x.
Mycogone perniciosa is a mycoparasite causing Wet Bubble Diseases (WBD) of Agaricus bisporus. In the present study, the whole genome of M. perniciosa strain MGR1 was sequenced using Illumina NextSeq500 platform. This sequencing generated 8.03 Gb of high-quality data and a draft genome of 39 Mb was obtained through a de novo assembly of the high-quality reads. The draft genome resulted into prediction of 9276 genes from the 1597 scaffolds. NCBI-based homology analysis revealed the identification of 8660 genes. Notably, non-redundant protein database analysis of the M. perniciosa strain MGR1 revealed its close relation with the Trichoderma arundinaceum. Moreover, ITS-based phylogenetic analysis showed the highest similarity of M. perniciosa strain MGR1 with Hypomyces perniciosus strain CBS 322.22 and Mycogone perniciosa strain PPRI 5784. Annotation of the 3917 genes of M. perniciosa strain MGR1 grouped in three major categories viz. biological process (2583 genes), cellular component (2013 genes), and molecular function (2919 genes). UniGene analysis identified 2967 unique genes in M. perniciosa strain MGR1. In addition, prediction of the secretory and pathogenicity-related genes based on the fungal database indicates that 1512 genes (16% of predicted genes) encode for secretory proteins. Moreover, out of 9276 genes, 1296 genes were identified as pathogenesis-related proteins matching with 51 fungal and bacterial genera. Overall, the key pathogenic genes such as lysine M protein domain genes, G protein, hydrophobins, and cytochrome P450 were also observed. The draft genome of MGR1 provides an understanding of pathogenesis of WBD in A. bisporus and could be utilized to develop novel management strategies.
Auditory deficits associated with the frings MGR1 (mass1) mutation in mice
Dev Neurosci 2005;27(5):321-32.PMID:16137990DOI:10.1159/000086712.
The gene responsible for the audiogenic seizure (AGS) phenotype in Frings mice, which was identified and originally designated Mass1, is now referred to as MGR1. Although the function of the gene product is not known, the expression pattern suggests a role in the developing CNS. Hearing impairment is often observed in AGS-susceptible rodents and is thought to contribute to the pathology of AGS. We therefore hypothesized that the Frings mouse exhibits early-onset hearing impairment and that the Frings MGR1 mutation is responsible for the hearing impairment phenotype that leads to the development of AGS susceptibility. Auditory brainstem response (ABR) thresholds were used to evaluate auditory function in mice carrying the Frings MGR1 allele and were compared with other AGS-susceptible and -resistant mice. ABR testing demonstrated that mice possessing the Frings MGR1 allele exhibit a mild to moderate level of hearing impairment that is present during the days following hearing onset. Furthermore, the hearing impairment resulting from the Frings MGR1 allele is relatively stable, which explains the long duration of AGS susceptibility exhibited by Frings mice compared with other AGS-susceptible mice.
Multidrug-resistance-associated protein MGr1-Ag is identical to the human 37-kDa laminin receptor precursor
Cell Mol Life Sci 2002 Sep;59(9):1577-83.PMID:12440778DOI:10.1007/s00018-002-8531-6.
We report the isolation and functional characterization of the gene encoding MGr1-Ag, a multidrug-resistance-associated protein. A lambdagt11 cDNA library derived from colorectal carcinoma SW480 cells was screened with monoclonal antibody MGR1. DNA homology analysis of 22 positive clones (designated R1-R22) suggested human 37-kDa laminin receptor precursor (37LRP, R7/R9/R15/R16/R19/R20) and a novel gene (R22) as candidate genes encoding MGr1-Ag. Western blot analysis showed that anti-R20 serum reacted with a unique protein band that was consistent with MGr1-Ag, while anti-R22 serum could not react with MGr1-Ag. The coding gene for MGr1-Ag was amplified using reverse transcription-PCR. Sequence analysis revealed that the MGr1-Ag and 37LRP genes shared the same coding sequence. An in vitro drug sensitivity assay indicated that down-regulation of 37LRP by an antisense technique could significantly enhance the cytotoxicity of anticancer drugs to gastric cancer cells. Thus we draw the conclusion that MGr1-Ag is identical to 37LRP.
A tonoplast-localized magnesium transporter is crucial for stomatal opening in Arabidopsis under high Mg2+ conditions
New Phytol 2022 Nov;236(3):864-877.PMID:35976788DOI:10.1111/nph.18410.
Plant stomata play an important role in CO2 uptake for photosynthesis and transpiration, but the mechanisms underlying stomatal opening and closing under changing environmental conditions are still not completely understood. Through large-scale genetic screening, we isolated an Arabidopsis mutant (closed stomata2 (cst2)) that is defective in stomatal opening. We cloned the causal gene (MGR1/CST2) and functionally characterized this gene. The mutant phenotype was caused by a mutation in a gene encoding an unknown protein with similarities to the human magnesium (Mg2+ ) efflux transporter ACDP/CNNM. MGR1/CST2 was localized to the tonoplast and showed transport activity for Mg2+ . This protein was constitutively and highly expressed in guard cells. Knockout of this gene resulted in stomatal closing, decreased photosynthesis and growth retardation, especially under high Mg2+ conditions, while overexpression of this gene increased stomatal opening and tolerance to high Mg2+ concentrations. Furthermore, guard cell-specific expression of MGR1/CST2 in the mutant partially restored its stomatal opening. Our results indicate that MGR1/CST2 expression in the leaf guard cells plays an important role in maintaining cytosolic Mg2+ concentrations through sequestering Mg2+ into vacuoles, which is required for stomatal opening, especially under high Mg2+ conditions.
