Conserved motifs in the promoter region of exon1A of hs_ , mm_ and ol_pmp22. The figure shows the positions of conserved regulatory motifs for pmp22 transcription. The numbers indicate the position relative to each TSS. The hs_ and mm_pmp22 have half of the CREB site (TGAC). The ol_pmp22 has the TG variant of CREB site (TGATGTCA). The position and sequence of the FP330 motif B (CTCTCAGGC) are conserved.
