Paired-like homeobox transcription factor involved in embryogenesis (PubMed:27578796, PubMed:30479355). May act as a regulator of embryo genome activation (PubMed:27578796). Binds to a 36 bp DNA elements containing a 5'-TAATCC-3' sequence motif, referred to as EEA motif (EGA-enriched Alu-motif), present in the promoters of target genes activated in early embryos (PubMed:27578796, PubMed:30479355). Inactive transcriptional activity. During early embryo development, its expression is restricted to the 4-cell to 8-cell stage of the preimplantation embryo. The homeobox contain essential residues (Ile-54, Lys-57, Ala-61) for binding to the 5'-TAATCC-3' motif of the targe gene promoters. The homeobox is incomplete and cannot bind to the 36 bp motif found in the promoters of the target genes. The 9aaTAD motif is a conserved putative nine amino acid transactivation motifs in C-terminus of the LEUTX region. Belongs to the paired homeobox family.
