Potential regulatory regions identified as conserved regions upstream of LWS across seven teleost species, including X. helleri. (A) Region I: 90 bp of conserved sequence. Black brackets indicate regions with 100 percent shared sequence identity across the seven teleosts shown. Two putative hormone response element (HRE) half-site arrangements are boxed in black. (B) Region II: 106-107 bp of conserved sequence. Four putative CRX binding sites and a single HRE half-site are boxed in black. Black arrows in (A) and (B) indicate sequence direction of HRE half-sites. Bp locations of both regions in relation to the start codon of the LWS gene are indicated for each species at the left and right of the alignments.
