MS31 is a potent, cell permeable, highly affinity, and highly selective fragment-like methyllysine reader protein spindlin 1 (SPIN1) inhibitor, which potently inhibits the interactions between SPIN1 and H3K4me3 (IC50=77 nM, AlphaLISA; 243 nM, FP). It selectively binds Tudor domain II of SPIN1 (Kd=91 nM). MS31 potently inhibits binding of trimethyllysine-containing peptides to SPIN1, and is not toxic to nontumorigenic cells[1]. IC50: 77 nM (SPIN1 by AlphaLISA), 243 nM (SPIN1 by FP)[1]Kd: 91 nM (SPIN1)[1]
MS31 potently inhibits binding of trimethyllysine-containing peptides to SPIN1, displays high binding affinity, is highly selective for SPIN1 over other epigenetic readers and writers, directly engages SPIN1 in cells, and is not toxic to nontumorigenic cells. MS31 selectively binds tudor domain II of SPIN1[1].

Conversion of various aromatic compounds by resting cells of Fusarium moniliforme strain MS31
J Biosci Bioeng 2001;92(4):381-4.PMID:16233114DOI:10.1263/jbb.92.381.
Resting cells of Fusarium moniliforme strain MS31 convert propylbenzene to 1-phenylpropanol with high regio- and stereospecificity. To elucidate the scope of substrate acceptability by the fungus, we used various aromatic compounds for the bioconversion. The fungus hydroxylated various alkylbenzenes at the benzylic position to produce optically active alcohols. Butylbenzene was converted to nonbenzylic alcohols. In all cases, the R absolute configuration of products was more abundant. Aromatic compounds with linear side chains and (1-methylethyl)benzene were converted to their corresponding alcohols with an enantiomeric excess of 94% to 100%. Further oxidation of the alcohols was detected, but it was weak.
Involvement of cytochrome P450 in hydroxylation of propylbenzene by Fusarium moniliforme strain MS31
J Biosci Bioeng 2001;92(6):580-4.PMID:16233150DOI:10.1263/jbb.92.580.
Fusarium moniliforme strain MS31 can oxidize propylbenzene to (R)-1-phenylpropanol with what may be a cytochrome P450. Hydroxylation of propylbenzene needed molecular oxygen, and NADPH as a coenzyme gave a higher yield than NADH. The hydroxylation proceeded further when FAD and FMN were added than in their absence, suggesting that the enzyme was a flavo-protein. Carbon monoxide inhibited the hydroxylation, as did other cytochrome P450 inhibitors such as SKF 525A and miconazole. These characteristics matched those of a microsomal cytochrome P450 monooxygenase system that contained NADPH-cytochrome P450 reductase.
Optimal conditions for production of (R)-1-phenylpropanol by Fusarium moniliforme strain MS31
J Biosci Bioeng 2001;92(3):288-93.PMID:16233098DOI:10.1263/jbb.92.288.
Resting cells of Fusarium moniliforme strain MS31 produced (R)-1-phenylpropanol from propylbenzene. The components of the medium and the reaction conditions were adjusted to increase the specific activity of the hydroxylating enzyme involved. Glucose and sodium nitrate were selected as carbon and nitrogen sources, respectively. The substrate, propylbenzene, inhibited fungal growth and the activity of the enzyme. Acetoin added to the medium increased both growth and activity of the enzyme, and hydroxylation of propylbenzene increased by 1.4-fold. Maximum bioconversion of propylbenzene by resting cells of the fungus was at 25-30 degrees C and pH 7.0 with cells at concentration of 40 mg (dry) per milliliter of reaction mixture. Conversion was accelerated as soon as propylbenzene was added; slowing 2 h later. In the end, F. moniliforme strain MS31 produced (R)-1-phenylpropanol with an enantiomeric excess of 98% at the concentration of 16 mM (2.2 mg.ml(-1)).
DNA polymorphism in Greenland. Allele and profile frequencies in a Greenland population sample using the VNTR probes MS1, MS31, MS43a and YNH24
Int J Legal Med 1994;106(5):254-7.PMID:7915134DOI:10.1007/BF01225415.
Allele frequencies obtained by RFLP (Restriction Fragment Length Polymorphism) analysis using the VNTR (Variable Number Tandem Repeats) single locus probes MS1, MS31, MS43a and YNH24 on HinfI-restricted DNA in a Greenland Eskimo (155 individuals) and a Danish Caucasian (616 individuals) population sample are reported. For MS1 the frequency distributions were almost identical whereas minor but significant differences were seen for the other 3 probes. The distribution of the frequencies of 139 Greenland complete DNA profiles was estimated using the Greenland and the Danish database. The average profile frequencies obtained with the Greenland database were approximately 10 times higher than the estimates obtained with the Danish database.
[Follow-up of allogenic bone marrow graft with DNA polymorphisms. Use of two minisatellite MS31 and MS43 probes. Comparison with data of chromosomal polymorphisms]
Presse Med 1995 Mar 18;24(11):523-6.PMID:7770390doi
Objectives: Allogenic bone marrow transplantation is widely used to treat many diseases of the haemopoietic system as well as metabolic disorders. Follow-up is essential to assess acceptance, rejection or post-graft relapse. This study was undertaken to evaluate the usefulness of the minisatellite probes MS31 and MS43 used as a routine follow-up test after bone marrow transplantation. Methods: Twenty receivers of allogenic bone marrow transplants were followed-up. Two monoclonal minisatellite probes, MS31 and MS43, were used for comparison with the classical polymorphism methods. Results: Fourteen cases of total chimeras, 3 cases of rejections and 3 cases of mixed chimeras were observed with the molecular probe techniques. In 19 of the 20 cases, this technique gave results compatible with classical polymorphism results. Conclusions: The minisatellite probes MS31 and MS43 were found to be sensitive, effective tests for bone marrow transplants which can be used in routine follow-up.
