Conserved cis-elements in mouse, human, and rat Pss1 promoters. Alignment of the mouse Pss1 promoter (Mm) (−398/−208-bp upstream of transcriptional start site) with human (Hs) and rat (Rn) sequences. Position +1 refers to the transcriptional start site. Nucleotides conserved among species are highlighted in gray. Putative Sp1 binding sites are underlined; E-box elements are boxed.
