Research Backgrounds
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.
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.

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.
Binds DNA as a monomer. Interacts (via C-terminus) with EP300 and CREBBP.
The two homeobox domains are arranged in a head-to-head orientation when bound to double-stranded DNA, each domain binding to one of the two DNA strands. Together, the homeobox domains can be considered to bind DNA with the consensus sequence 5'-TAATCTAATCA-3', but due to the head-to-head orientation of the DNA-bound domains, the first homeobox domain binds to the consensus sequence 5'-TAAT-3', and the second homeobox domain binds DNA on the opposite strand, with the consensus sequence 5'-TGAT-3' (PubMed:30322619, PubMed:30540931). Both homeobox domains confer nuclear targeting (PubMed:15709750).
The C-terminal region is required for efficient activation of transcription from target promoters (PubMed:26951377, PubMed:29618456). It mediates interaction with EP300 and CREBBP (PubMed:26951377).
Belongs to the paired homeobox family.
