Alignment of the leHSP90 amino acid sequence of known HSP90s. The five HSP90 family signature sequences and the consensus sequence MEEVD at the C-terminus are in shadow. The amino acids are numbered along the right margin. The common names, species names, and GenBank accession numbers are as follows: oyster, Crassostrea gigas, ABS18268; Zhikong scallop, Chlamys farreri, AAR11781; bay scallop, Argopecten irradians, ABS50431; abalone, Haliotis tuberculata, CAK95235; zebrafish, Danio rerio, NP_571403 (HSP90α), O57521 (HSP90β); chicken, Gallus gallus, CAA49704 (HSP90β); human, Homo sapiens, NP_005339 (HSP90α), NP_031381 (HSP90β); rat, Rattus norvegicus, NP_786937 (HSP90α), P34058 (HSP90β); bovine, Bos taurus, NP_001012688 (HSP90α)
