From: Proteomic characterization and evolutionary analyses of zona pellucida domain-containing proteins in the egg coat of the cephalochordate, Branchiostoma belcheri

Figure 6

The alignment of three zona pellucida domains from three ZP proteins from B . belcheri (BbZP1), P. marinus (lamprey ZPAX), and Oryzias latipes (Ol ZPB) showing sequence homologies between the cephalochordate and vertebrate ZP proteins. The cysteine residues that are critical for the function and identity of ZP domains are boxed. Positions that are identical in at least two ZP proteins are boxed.
