CpG islands and regulatory elements in sirt3 of gilthead sea bream. a Schematic representation of the CpG island (CGI) in sirt3 of gilthead sea bream (in blue). Yellow lines represent CpG sites. Numbers indicate the position of the putative transcription start site (TSS, black arrow) and the starting and ending point of the first exon (red box) and intron (red line) with respect to the start codon (ATG, red). b Regulatory elements in sirt3 of gilthead sea bream. The first intron sequence was replaced by an indication of their length. Lower case letters indicate a 2.37-kb sequence upstream of the translational start site ATG and include the first exon and the first intron, as well as the 5′ UTR and the 5′ flanking region. The putative TSS is shaded in black. Predicted regulatory elements are indicated in bold, underlined, lower case italics. CGI is shaded in gray. The analyzed CpG positions are shaded in red
