Figure 5From: GPR50 is the mammalian ortholog of Mel1c: Evidence of rapid evolution in mammalsSchematic diagram of the Mel1c/GPR50 gene organization in zebrafish, chicken, opossum, mouse, man, and horse. The stop codon following the second exon in zebrafish and chicken is replaced by the insertion of a protein fragment reminiscent of a DNA directed RNA polymerase II in mammals (light color).Back to article page
