PRP PROTEINS Meaning and
Definition
-
PrP proteins, short for Prion Protein Proteins, are a class of proteins that play a crucial role in maintaining healthy cellular function in vertebrates, including humans. These proteins are primarily found in the neurons of the central nervous system. The PrP proteins are notable for their involvement in transmissible spongiform encephalopathies (TSEs), a group of fatal neurodegenerative disorders.
PrP proteins are encoded by the PRNP gene, which is highly conserved across different species. These proteins are believed to be involved in cell signaling, synaptic function, and protection against oxidative stress. However, an abnormal form of PrP protein, called PrPSc, has been associated with the development of prion diseases.
Prion diseases are characterized by the conversion of the normal, soluble PrP proteins into an insoluble, aggregated form. This process leads to the accumulation of PrPSc in different tissues, specifically in neurons, resulting in neuronal loss and the formation of spongiform vacuoles in the brain. These diseases include Creutzfeldt-Jakob disease (CJD), variant CJD, fatal familial insomnia, and Gerstmann-Sträussler-Scheinker syndrome.
The exact mechanism of PrPSc formation and its pathogenicity is not fully understood. However, it is believed that the abnormal protein can induce conformational changes in the normal PrP proteins, causing them to misfold and aggregate. These aggregated proteins can then propagate and generate more misfolded PrPSc, leading to the progressive neurodegeneration observed in prion diseases.

Etymology of PRP PROTEINS
The term "PrP proteins" is derived from the phrase "prion protein". The word "prion" was coined in 1982 by Stanley B. Prusiner, a neurologist and biochemist, to describe an infectious particle that was responsible for causing several degenerative neurological diseases, including Creutzfeldt-Jakob disease (CJD) in humans and bovine spongiform encephalopathy (BSE) in animals.
The "P" in "PrP" stands for "prion", while the "Pr" comes from Prusiner's last name. The "PrP protein" refers specifically to the cellular isoform of the prion protein, which is encoded by the PRNP gene.
