MBNL1 Antibody

2. Functional depletion of the alternative splicing factors Muscleblind-like (MBNL 1 and 2) is at the basis of the neuromuscular disease myotonic dystrophy type 1 (DM1). Here, we screen for miRNAs that regulate MBNL1 and MBNL2 in HeLa cells. We thus identify miR-23b and miR-218, and confirm that they downregulate MBNL proteins in this cell line. PMID: 29946070
3. For exogenous activation of MBNL transcription, MBNL1 transcription start site T2 seems to be the most suitable target, as the ensuing pre-mRNA is susceptible to both major loops, e1 and e5, and hence, theoretically, following induction each cell in the body could reach the optimal MBNL content.

12. Reduced RBFOX1 activity in myotonic dystrophy type 1 tissues may amplify several of the splicing alterations caused by the deficiency in MBNL1. PMID: 25211016
13. MBNL1 binds with C allelic pre-miR-1307 leading to low expression of miR-1307-3p in colorectal cancer. PMID: 25977444
14. The result is consistent with the hypothesis that MBNL proteins are trapped by expanded CUG repeats and inactivated in myotonic dystrophy type 1 (DM1) and that CELF1 is activated in DM1. PMID: 25403273
15. Results show that nuclear localization is a major determinant of MBNL1 function. It promotes the nuclear retention of repeat-containing transcripts, which results in repression of aberrant protein expression from the expanded repeats. PMID: 25274774
16. Results highlight the importance of RNA binding by MBNL Zinc Finger domains 1 and 2 for splicing regulatory activity, even when the protein is artificially recruited to its regulatory location on target RNAs. PMID: 24373687
17. both MBNL1 and MBNL2 are involved in the regulation of Tau exon 2 splicing and the mis-splicing of Tau in DM1 is due to the combined inactivation of both. PMID: 24440524
18. MBNL1 and RBFOX2 cooperate to establish a splicing programme involved in pluripotent stem cell differentiation. PMID: 24048253
19. MBNL1 is highly mobile and changes localization in response to altered transcription and splicing activity, providing an insight into the sensitivity of the lens to changes in MBNL1 distribution. PMID: 24354850
20. in both dystrophic and sarcopenic muscles MBNL1 undergoes intranuclear relocation, accumulating in its usual functional sites but also ectopically moving to domains which are usually devoid of this protein in healthy adults PMID: 23807294
21. This report demonistrated that the association of several genetic variants of the MBNL1 gene with DM1 or with the severity of the disease. PMID: 23161457
22. consistent with a central and negative regulatory role for MBNL proteins in pluripotency, their knockdown significantly enhances the expression of key pluripotency genes and the formation of induced pluripotent stem cells during somatic cell reprogramming PMID: 23739326
23. MBNL1 loss shows a graded effect on the number and severity of the ensuing RNA splice defects. PMID: 23166594
24. study suggests that regulation of CUGBP1 and MBNL1 is essential for accurate control of destabilization of a broad spectrum of mRNAs as well as of alternative splicing events PMID: 22355723
25. It was demonstrated that functionally distinct classes of MBNL1-mediated splicing events exist as defined by requirements for zinc finger-RNA interactions. PMID: 22890842
26. The present results show that the MBNL1 protein is expressed and more or less sequestered into the CCUGexp nuclear foci also in analyzed non-muscle tissues of DM2 patients. PMID: 22520280
27. congenital myotonic dystrophy muscle has nuclear foci that contain muscleblind-like 1 (MBNL1) protein. PMID: 22113158
28. The removal of one pair of zinc fingers greatly impairs the binding affinity of MBNL1, which indicates that the two pairs of zinc fingers might possibly interact with RNA targets cooperatively. PMID: 22106026
29. Common variants near MBNL1 and NKX2-5 are associated with infantile hypertrophic pyloric stenosis. PMID: 22306654
30. Expanded CUG repeats Dysregulate RNA splicing by altering the stoichiometry of the muscleblind 1 complex PMID: 21900255
31. Deletion of the MBNL1 response element eliminated MBNL1 splicing regulation and led to complete inclusion of exon 5, which is consistent with the suppressive effect of MBNL1 on splicing. PMID: 21832083
32. Although MBNL1 contains four Zn fingers, it appears that only two Zn fingers binding GC motifs are necessary for high affinity RNA binding. PMID: 21548961
33. MBNL1 regulates pre-miR-1 biogenesis. PMID: 21685920
34. results indicate the occurrence of a mis-splicing event in myotonic dystrophy type 1 that is induced neither by a loss of muscleblind-like 1 (MBNL1) function nor by a gain of CUGBP1 PMID: 21439371
35. the abnormally high inclusion of the exon 5 and 7 regions in DM1 is expected to enhance the potential of MBNL1 of being sequestered with nuclear CUG expansions, which provides new insight into DM1 pathophysiology. PMID: 21454535
