The genomic structure of the POU domain containing oct-1 gene (OTF1 locus) coding region has been determined using human DNA recombinant bacteriophage and a yeast artificial chromosome clone. The gene is encoded by 16 exons spanning over 150 kb, and the Oct-1 protein reading frame has been extended to 766 amino acids. The exonic structure has been compared to the mouse Oct-2 protein and reveals a conservation of exon-intron boundaries as well as protein sequence similarity. To provide insight into Oct-1 control of transcriptional regulation during the cell-cycle the expression of the oct-1 gene was examined during cellular DNA replication and shows that the steady-state level of the oct-1 mRNA is not S-phase regulated.
