靶點(diǎn)詳情

  • 功能:
    Mediates pre-mRNA alternative splicing regulation. Acts either as activator or repressor of splicing on specific pre-mRNA targets. Inhibits cardiac troponin-T (TNNT2) pre-mRNA exon inclusion but induces insulin receptor (IR) pre-mRNA exon inclusion in muscle. Antagonizes the alternative splicing activity pattern of CELF proteins. Regulates the TNNT2 exon 5 skipping through competition with U2AF2. Inhibits the formation of the spliceosome A complex on intron 4 of TNNT2 pre-mRNA. Binds to the stem-loop structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Binds to the 5'-YGCU(U/G)Y-3'consensus sequence. Binds to the IR RNA. Binds to expanded CUG repeat RNA, which folds into a hairpin structure containing GC base pairs and bulged, unpaired U residues.
  • 基因功能參考文獻(xiàn):
    1. RBFOX1/MBNL1 competition for CCUG RNA repeats binding contributes to myotonic dystrophy type 1/type 2 differences. PMID: 29789616
    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. PMID: 28949831
    4. RAN Translation Regulated by Muscleblind Proteins in Myotonic Dystrophy Type 2 PMID: 28910618
    5. Our work suggests that DM1 patients are at risk for Fuchs' endothelial corneal dystrophy (FECD). DMPK mutations contribute to the genetic burden of FECD but are uncommon. We establish a connection between two repeat expansion disorders converging upon RNA-MBNL1 foci and FECD. PMID: 28886202
    6. Binding of the MBNL zinc fingers to cardiac troponin T pre-mRNA is specific and relatively simple, unlike the complex multiple dimer-trimer stoichiometries postulated in some previous studies. PMID: 28718627
    7. Heterozygous missense mutations and one in-frame deletion in MBNL1 were identified in 3 myotonic dystrophy patients. PMID: 27222292
    8. Nuclear retention of full-length HTT RNA is mediated by splicing factors MBNL1 and U2AF65 PMID: 26218986
    9. muscleblind-like 1 (MBNL1) is a robust suppressor of multiorgan breast cancer metastasis. It binds the 3' untranslated regions of DBNL and TACC1 -two genes that are implicated as metastasis suppressors. PMID: 26883358
    10. Sense DMPK RNA foci clearly co-localize with MBNL1 and MBNL2 proteins and accumulate in myotonic dystrophy 1 tissues during development. PMID: 26339785
    11. abnormal splicing of DMD exon 78 found in dystrophic muscles of DM1 patients is due to the functional loss of MBNL1 and leads to the re-expression of an embryonic dystrophin in place of the adult isoform. PMID: 26018658
    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
    36. Findings demonstrate a role for Mbnl1 in controlling insulin receptor exon 11 inclusion via binding to a downstream intronic enhancer element. PMID: 20519504

    38. small interfering RNA-mediated down-regulation of MBNL1 in normal myoblasts results in abnormal insulin receptor splicing PMID: 15546872
    39. The GFP-MBNL1 in CUG and CAG foci have similar half-times of recovery and fractions of immobile molecules, suggesting GFP-MBNL1 is bound by both CUG and CAG repeats and formation of RNA foci and disruption of MBNL1-regulated splicing are separable events. PMID: 15961406
    40. The fact that a human protein works in a Drosophila cellular context illustrates the use of an in vivo test to prove functional conservation. PMID: 16394256
    41. findings show that MBNL1 nuclear sequestration in protein foci is a molecular pathology marker of DM1 and DM2 patients where ribonuclear inclusions of transcripts with expanded CUG/CCUG repeats are also present PMID: 16920640
    42. Elevated levels of MBNL1 show RNA-independent interaction with hnRNP H and dampen the inhibitory activity of increased hnRNP H levels on IR splicing in normal myoblasts. PMID: 16946708
    43. MBNL1 (muscleblind-like protein 1) is an alternative splicing factor that becomes highly concentrated with mutant RNA foci. PMID: 17846170

    47. MBNL1 and MBNL2 always co-distributed. Functional differences between MBNL1 and MBNL2 have not yet been found PMID: 19095965
    48. Our data seem indicate that the presence of ribonuclear inclusions and MBNL1 nuclear foci are involved in alteration of alternative splicing but do not impair DM2 myogenic differentiation. PMID: 19345584
    49. Data show that ligand 1 selectively destabilizes the MBNL1N-poly(CUG) complex. PMID: 19805260
