abstract：:We identified cDNAs coding for homologues to tetrapod prion proteins (PrPs) in Atlantic salmon (Salmo salar) and Japanese pufferfish (Fugu rubripes), which were termed 'similar to PrPs' (stPrPs). Besides significant sequence homologies the fish stPrPs display characteristic structural features in common with tetrapod ...
