The doppel protein (Dpl) is a newly recognized cellular prion protein (PrP(C))-like molecule encoded by a novel gene locus, PRND, located on the same chromosomal region of the PrP(C) coding gene. Recently, Dpl was shown to be aberrantly expressed in astrocytic tumor specimens and in astrocytoma-derived cell lines, showing a peculiar cytoplasmic localization. Here, Dpl interactions with some of the prion-interacting proteins were studied. In particular, whether the tumor astrocytic environment is suitable for doppel interaction with GFAP and Grb2 proteins, as well as with the PrPC protein itself was investigated.
