Amino Acid Sequence of Three Prion Protein Fragments

	120										130										140				144
Human	A	V	V	G	G	L	G	G	Y	M	L	G	S	A	M	S	R	P	I	I	H	F	G	S	D
Bank Vole	A	V	V	G	G	L	G	G	Y	M	L	G	S	A	M	S	R	P	M	I	H	F	G	N	D
Syrian Hamster	A	V	V	G	G	L	G	G	Y	M	L	G	S	A	M	S	R	P	M	M	H	F	G	N	D

Note: mouse prion has the same PrP(120–144) sequence as bank vole. The letters colored in red are residues mutated from human sequence to bank vole and Syrian hamster sequences.
