Western blot analysis of Dux on different lysates. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in PBS for 1 hour at room temperature. The primary antibody (ER1901-52, 1/500) was used in 5% BSA at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1:5,000 dilution was used for 1 hour at room temperature.<br />

  • Immunohistochemical analysis of paraffin-embedded rat testis tissue using anti-Dux antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 20 minutes. The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ER1901-52, 1/200) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

  • Flow cytometric analysis of Dux was done on MG-63 cells. The cells were fixed, permeabilized and stained with the primary antibody (ER1901-52, 1/50) (red). After incubation of the primary antibody at room temperature for an hour, the cells were stained with a Alexa Fluor 488-conjugated Goat anti-Rabbit IgG Secondary antibody at 1/1000 dilution for 30 minutes.Unlabelled sample was used as a control (cells without incubation with primary antibody; black).

TISSUE SPECIFICITY

Isoform 1: Does not seem to be expressed in normal muscle, but is detected in muscle of individuals with FSHD, and also in testis (at protein level). Isoform 1: Does not seem to be expressed in normal muscle, but in muscle of individuals with FSHD, where it may be toxic to cells. Isoform 2: Detected in skeletal muscle, fibroblasts and testis from healthy individuals.

DEVELOPMENTAL STAGE

Isoform 1: Detected in embryos at the 4-cell stage. Not detected in embryos at the 2-cell stage, or at the 8-cell stage (at protein level). Detected in embryos at the 4-cell stage. Not detected in embryos at the 2-cell stage, or at the 8-cell stage. Detected in induced pluripotent (iPS) cells, but expression is suppressed upon differentiation to embryoid bodies. Isoform 2: Detected in embryoid bodies derived from induced pluripotent (iPS) cells, but not in the induced pluripotent (iPS) cells themselves.

SUBCELLULAR LOCATION

[Isoform 1]: Nucleus. Note=Actively transported through the nuclear pore complex (NPC).; [Isoform 2]: Nucleus.

FUNCTION

[Isoform 1]: Transcription factor that is selectively and transiently expressed in cleavage-stage embryos. Binds to double-stranded DNA elements with the consensus sequence 5'-TAATCTAATCA-3'. Binds to chromatin containing histone H3 acetylated at 'Lys-27' (H3K27ac) and promotes deacetylation of H3K27ac. In parallel, binds to chromatin that lacks histone H3 acetylation at 'Lys-27' (H3K27ac) and recruits EP300 and CREBBP to promote acetylation of histone H3 at 'Lys-27' at new sites. Involved in transcriptional regulation of numerous genes, primarily as transcriptional activator, but mediates also repression of a set of target genes. Promotes expression of ZSCAN4 and KDM4E, two proteins with essential roles during early embryogenesis. Heterologous expression in cultured embryonic stem cells mediates also transcription of HERVL retrotransposons and transcripts derived from ACRO1 and HSATII satellite repeats. May activate expression of PITX1. May regulate microRNA (miRNA) expression. Inappropriate expression can inhibit myogenesis and promote apoptosis.; [Isoform 2]: Probably inactive as a transcriptional activator, due to the absence of the C-terminal region that is important for transcriptional activation. Can inhibit transcriptional activation mediated by isoform 1. Heterologous expression of isoform 2 has no deleterious effect on cell survival.
