doi: 10.3390/cells11081271

Figure Lengend Snippet: Schematic representation of mouse and human β3-AR genes including their upstream sequences. ( A ) In the mouse gene, 5 exons (E1–E5; solid boxes) and 4 introns (dashed lines) are depicted. They potentially express up to 6 different alternative mRNAs of which 3 codify for the canonical β3-AR protein (yellow mRNAs) while the other 3 for an alternative β3-AR protein with a different C-terminal sequence (purple mRNAs). The putative transcription-start site (TSS) is indicated by the red arrow. The positions of the 6 potential HBSs relative to the TSS are in green. All of them contain the minimal HBS consensus sequence (underlined sequence 5′-ACGTG-3′). ( B ) In the human gene, the positions of the 6 potential HBSs relative to the TSS are in green. All of them contain the minimal consensus sequence (underlined sequence 5′-ACGT-3′). The putative TSS is indicated by the red arrow. The highly conserved nucleotides G −2 and/or C +5 in the mouse and human HBSs sequence are highlighted in red.
