GeneID: 4154 Human MBNL1

Swiss-port # Q9NR56 Human Muscleblind-like protein 1

Gene Symbol MBNL1
Gene Full Name muscleblind-like splicing regulator 1
Background This gene encodes a member of the muscleblind protein family which was initially described in Drosophila melanogaster. The encoded protein is a C3H-type zinc finger protein that modulates alternative splicing of pre-mRNAs. Muscleblind proteins bind specifically to expanded dsCUG RNA but not to normal size CUG repeats and may thereby play a role in the pathophysiology of myotonic dystrophy. Mice lacking this gene exhibited muscle abnormalities and cataracts. Several alternatively spliced transcript variants have been described but the full-length natures of only some have been determined. The different isoforms are thought to have different binding specificities and/or splicing activities. [provided by RefSeq, Sep 2015]
Function 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.

    Immunocytochemistry: HeLa cells were stained with ARG10721 anti-MBNL1 antibody [1H1] at 1: 1000. Muscleblind-like protein 1 is present in the nucleus of HeLa cells (red). Co-staining is with a rabbit polyclonal antibody against vimentin (red) reveals cytoplasmic intermediate filaments.  Blue is a DNA stain which largely colocalizes with the MBNL1 protein in the nucleus.

    Immunofluorescence: HeLa cells stained with ARG10721 anti-MBNL1 antibody [1H1] (green) at 1:1000 dilution and costained with ARG10757 anti-Hsp 60 antibody (red) at 1:5000 dilution.

    The MBNL1 antibody specifically labels nuclei, while the Hsp 60 antibody reveals protein expressed in mitochondria.

    Western blot: HEK293 (cytosol), HEK293 (nuclear), NIH/3T3 (cytosol), NIH/3T3 (nuclear), HeLa (cytosol) and HeLa (nuclear). The blots were stained with ARG10721 anti-MBNL1 antibody [1H1] (green) at 1:1000 dilution.

    MBNL1 protein is predominantly detected in the nuclear enriched fractions. This antibody binds to the Human protein and does not bind the rodent homologue.
