Alignment of amino acid sequences of ZPB around the mid-ZPd sites. The sequences of euteleostean ZPB are highlighted by the gray box. Arrowheads indicate the mid-ZPd cleavage sites. The proline residues are shown by white letters in a black box. The name of the ZPB genes and their source are as follows. eZPB, Japanese eel; AcZPBb, Japanese anchovy Engraulis japonicus; HgZPBb, Pacific herring Clupea pallasii; MfZPB, milkfish; zfZP2, zebrafish; gfZP2, goldfish Carassius auratus auratus; carpZP2_3, carp Cyprinus carpio; rtVEPα and rtVEPβ, rainbow trout Oncorhynchus mykiss; wfChgH, winter flounder Pseudopleuronectes americanus; FhChgH and FhChgHm, killifish; GaChgH and GaChgHm, three-spined stickleback Gasterosteus aculeatus, and OlChgH and OlChgHm, medaka.
