Description

General description

The protein named PrP is the cellular gene for the prion protein. The normal form appears to play a role in neuronal development and synaptic plasticity, iron transport and myelin sheath maintenance. PrP has both membrane associated and cytoplasmic/nuclear isoforms. The primary isoform is localized to the cellular membrane in lipid anchor clusters, as well as in the Golgi. Isoform 2 is cytoplasmic that becomes localized to the nucleus. Prp is normally a monomeric protein but a disease associated mutated form will form protease resistant oligomers often with another protein beta amyloid. The mutated form is found in high quantity in the brain of humans and animals infected with the degenerative neurological diseases such as Kuru, Creutzfeldt-Jakob disease (CJD), Gerstmann-Straussler syndrome (GSS), Scrapie, and Bovine Spongiform Encephalopathy (BSE) and Transmissible Mink Encephalopathy.

Specificity

DRM1-60 showed strong binding to only one peptide (#29: NQVYYRPVDQYS) suggesting a linear epitope corresponding to SHaPrP(159–170), located in b2-a2 loop. This epitope assignment is consistent with the binding of DRM1-60 to PrPC to all species tested, except human and horse, which both harbor substitutions in this region. While antibodies with epitopes similar to DRM2-118 have been described,(36) DRM1-60 and DRM1-31 have unique epitopes not previously reported. DRM1-60 appears to bind a linear epitope localized to the b2-a2 loop, while DRM1-31 has a conformational epitope located on the exposed surface formed by the close proximity of the b2-a2- helix loop, the N-terminus of the a2 helix, and the C-terminus of the a3 helix.

Immunogen

Recombinant protein corresponding to syrian hamster PrP.
