abstract：:Isolation and characterization of the cDNA coding for the 216-residue Xenopus laevis prion protein is reported. Existence of this protein in amphibians was suggested by an EST fragment (accession number BG813008), while a conclusive demonstration is presented here. This protein exhibits a higher identity level to avia...
