PMID- 10525406 OWN - NLM STAT- MEDLINE DCOM- 19991104 LR - 20101118 IS - 0022-2836 (Print) IS - 0022-2836 (Linking) VI - 292 IP - 4 DP - 1999 Oct 1 TI - Ataxia in prion protein (PrP)-deficient mice is associated with upregulation of the novel PrP-like protein doppel. PG - 797-817 AB - The novel locus Prnd is 16 kb downstream of the mouse prion protein (PrP) gene Prnp and encodes a 179 residue PrP-like protein designated doppel (Dpl). Prnd generates major transcripts of 1.7 and 2.7 kb as well as some unusual chimeric transcripts generated by intergenic splicing with Prnp. Like PrP, Dpl mRNA is expressed during embryogenesis but, in contrast to PrP, it is expressed minimally in the CNS. Unexpectedly, Dpl is upregulated in the CNS of two PrP-deficient (Prnp(0/0)) lines of mice, both of which develop late-onset ataxia, suggesting that Dpl may provoke neurodegeneration. Dpl is the first PrP-like protein to be described in mammals, and since Dpl seems to cause neurodegeneration similar to PrP, the linked expression of the Prnp and Prnd genes may play a previously unrecognized role in the pathogenesis of prion diseases or other illnesses.
