Doppel (Dpl), named for downstream prion protein-like[1], is a homolog of the prion protein (PrP). It is a cell surface glycoprotein.

Dpl has the same fold as PrP, with three alpha helices and two short beta strands[2]. however it differs in that the third helix has a significant kink in it and it also contains two disulphide bonds.
The structure mutant PrP with the additional disulphide bond was also determoned [3]
