The PRNP Polyclonal Antibody (PAC029180) is a valuable tool for researchers studying prion protein (PrP), a protein involved in neurodegenerative diseases such as Creutzfeldt-Jakob disease and mad cow disease. This antibody, produced in rabbits, exhibits high reactivity with human and mouse samples and is validated for use in immunohistochemistry and Western blot applications.PrP, also known as cellular prion protein, plays a crucial role in the pathogenesis of prion diseases by facilitating the conversion of normal cellular proteins into abnormal infectious forms.
Research into PrP is essential for developing diagnostic tools and therapeutic interventions for these devastating diseases. The PRNP Polyclonal Antibody enables reliable detection and analysis of PrP expression in various tissue types, making it a valuable asset for studies in neuroscience and neurodegenerative disease research.
Its primary physiological function is unclear. Has cytoprotective activity against internal or environmental stresses. May play a role in neuronal development and synaptic plasticity. May be required for neuronal myelin sheath maintenance. May play a role in iron uptake and iron homeostasis. Soluble oligomers are toxic to cultured neuroblastoma cells and induce apoptosis (in vitro). Association with GPC1 (via its heparan sulfate chains) targets PRNP to lipid rafts. Also provides Cu(2+) or ZN(2+) for the ascorbate-mediated GPC1 deaminase degradation of its heparan sulfate side chains.

NCBI Summary:
The protein encoded by this gene is a membrane glycosylphosphatidylinositol-anchored glycoprotein that tends to aggregate into rod-like structures. The encoded protein contains a highly unstable region of five tandem octapeptide repeats. This gene is found on chromosome 20, approximately 20 kbp upstream of a gene which encodes a biochemically and structurally similar protein to the one encoded by this gene. Mutations in the repeat region as well as elsewhere in this gene have been associated with Creutzfeldt-Jakob disease, fatal familial insomnia, Gerstmann-Straussler disease, Huntington disease-like 1, and kuru. An overlapping open reading frame has been found for this gene that encodes a smaller, structurally unrelated protein, AltPrp. Alternative splicing results in multiple transcript variants.
