Gene RIF (44)

26883358 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.
26339785 Sense DMPK RNA foci clearly co-localize with MBNL1 and MBNL2 proteins and accumulate in myotonic dystrophy 1 tissues during development.
26218986 Nuclear retention of full-length HTT RNA is mediated by splicing factors MBNL1 and U2AF65
26018658 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.
25977444 MBNL1 binds with C allelic pre-miR-1307 leading to low expression of miR-1307-3p in colorectal cancer.
25403273 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.
25274774 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.
25211016 Reduced RBFOX1 activity in myotonic dystrophy type 1 tissues may amplify several of the splicing alterations caused by the deficiency in MBNL1.
24440524 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.
24373687 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.
