We report the isolation and characterization of a cDNA coding for Fugu rubripes prion protein (PrP)-like of 180 amino acids which includes the PrP-conserved hydrophobic region homologous to that of Xenopus PrP. In addition to the hydrophobic region, Fugu PrP-like has several features common to PrPs, such as a signal sequence, a basic nature (pI 9.7) and a single intron in the 5' untranslated region. A possible glycosyl phosphatidylinositol (GPI) anchor site also exists in PrP-like. In expression analysis, PrP-like mRNA was detected in retina, skin, and brain, all of which express PrP mRNA in mammals. In a genome fragment clone (T002589, 31945 bp) sequenced by the Fugu Genomics Project, PrP-like located between KIAA0168 and SLC231A homologues. In human chromosome 20p13, PrP, Doppel, KIAA0168, and SLC231A align in this order. The close gene arrangement between the Fugu and human genomes suggests that Fugu PrP-like is a real orthologue of human PrP. However, Fugu PrP-like does not possess tandem repeats or a region with two glycosylation sites and a disulphide bridge. We do not declare that the cloned Fugu PrP-like represents fish PrP due to structural inconsistency, but believe that it will offer new insights into the evolution of PrPs from fish to tetrapods.
