Figure 4From: GPR50 is the mammalian ortholog of Mel1c: Evidence of rapid evolution in mammalsSequence alignment of chicken Mel1c, zebra fish Mel1c and human GPR50. Sequence identities are reported white on a black background, whereas sequence similarities are boxed. The positions of the transmembrane helices are reported above its sequence. Arrows indicate the positions of the amino acids that, in GPR50, evolved under positive selection.Back to article page
