Prion protein genes in caribou from Alaska.

Abstract excerpt

Prion protein genes were sequenced in free-ranging Alaska caribou (Rangifer tarandus grantii). Caribou prion alleles are identical or nearly so to those of wapiti, white-tailed deer, and mule deer. Five single-nucleotide polymorphisms were detected with substitutions at residues 2 (V-->M), 129 (G-->S), 138 (S-->N), 146 (N-->N), and 169 (V-->M). The 138N codon had been previously reported only in prion pseudogenes...
