The function of ENSG00000213921 (LEUTX, leucine twenty homeobox) is as follows. [Isoform 1]: 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). {ECO:0000269|PubMed:27578796, ECO:0000269|PubMed:30479355}. [Isoform 2]: Inactive transcriptional activity. .
