Positive Selection and the Evolution of izumo Genes in Mammals

Figure 4

Amino acid sequence alignment of IZUMO3 for species of the order Primates. Positively selected sites and protein domains are indicated as in Figure 3. Two letters are used to indicate species: Human (Homo sapiens—Hs), Chimpanzee (Pan troglodytes—Pt), Gorilla (Gorilla gorilla—Gg), Gibbon (Nomascus leucogenys—Nl), and Marmoset (Callithrix jacchus—Cj).
