Similarity relationship among the zebrafish ependymins and two previously known ependymin sequences. The amino acid similarity of two zebrafish ependymins (Danio_Bra and Danio_MERP) is higher across species (e.g., goldfish and human) than among the four different zebrafish molecules. Dark gray boxes denote brain-specific sequences (Danio_Bra and 1Carassius), whereas white and light gray boxes indicate non-brain specific sequences (Danio_Tj, Dan_LvItEm, Danio_MERP, and Epdr1_Homo). The linkage group (LG) or chromosome (Cr) where the gene is present is indicated in the black box next to each sequence (this information is currently not available for goldfish).
