Sequence alignment of H/E(spl)/Hey-related proteins from Fugu rubripes Conservation levels: 100% identical residues are indicated in black, 80% or more conserved residues are marked in dark grey, 60% or more conserved residues are marked in lighter grey and less than 60% conserved residues are indicated in very light grey. Naming of the Fugu proteins according to the zebrafish homologues, numbering corresponds to the contig in which they were identified (table 1).
