 Ontario Genomics Institute
Prions are naturally occurring proteins in animals – their normal functions, however, are not clear.
Disease-causing prions have the tendency to clump together with each other to form large aggregates – called amyloids – that are resistant to destruction or un-clumping.
Prion diseases can also be infectious, or transmitted; they can be passed between members of the same species, and occasionally passed from one species to the next.

 Turtle Prion Gene
The ancestral amniote prion: alignment of turtle, bird, mammal, and doppel
Mammalian prions are not particularly well conserved within the signal region; their alignment to bird prion signal is already somewhat dubious (only 2 of 9 avian sequences cover this region).
A paradoxical aspect of the prion protein is the evolution and function of the second loop (between alpha helix B and C).

All newly acquired birds should be examined by a veterinarian prior to a quarantine period of at least 30 days.
Your veterinarian will not be able to guarantee that your bird is free of disease, he/she will however, be able to look for the common indicators on physical exam and laboratory tests that my indicate that your pet is not in good health.

 Prion - Medicow
The prion theory has been controversial from the beginning, and although scientific evidence for the existence of such infectious particles has increased, an exact causal link between prions and the diseases they are believed to cause remains to be established.
The scientists conducted their studies using yeast prions, which are similar to the mammalian prions that have gained notoriety for their roles in such fatal brain-destroying human diseases such as Creutzfeldt-Jakob disease and kuru, and in the animal diseases BSE and scrapie.
Prion diseases are caused by misfolded versions of the prion protein, which cause other prion proteins to misfold and clump together in the brain.

 Doppel Delay
Prion exon 2 is baffling in its sequence conservation, which is much better than the seemingly more mission-critical exon 1 transcription start.
Prion mutations are autosomal dominant because amyloid represents toxic gain-of-function; doppel protein is unlikely to form amyloid because of poor homology to the 106-126 region.
If prion protein had this second disulfide pair, the effect would be to stabilize the loop between the second beta strand and the second alpha helix, which appear in the original Nature nmr ensemble as a fattened tube of relative positional uncertainty.

 Study Links Progressive Aphasia Syndrome to Prion Gene: National Institute of Neurological Disorders and Stroke (NINDS)
Therefore the prion gene is probably not the primary cause of the disease, he adds.
Previous studies have suggested that normal prion proteins carry out a variety of functions, from cellular delivery of copper to cell signaling and even triggering or preventing cell death.
"This is a new case where prion genes are linked to a neurological disorder, and it suggests that we need to learn more about the normal function of prions in the nervous system in order to better understand their role in disease," says Michael Nunn, Ph.D., the NIH neurology institute’s program director for this study.

 Petrels - Prions, gadfly, storm and diving petrels - Te Ara Encyclopedia of New Zealand
Fairy prions eat krill and other small crustaceans, which they either peck while sitting on the water or take while in flight, making only momentary contact with the water.
This is the largest prion and, as its name suggests, it has a broad bill with lamellae (comb-like fringes), which hang from the upper beak.
Broad-billed prions breed on islands off southern New Zealand and on the Chatham Islands, where the birds are abundant.

 Eau de prion? Seabirds can smell their mates, scientists say
One good reason to study odor detection in prions and other "tube-nosed" seabirds is that the birds are pretty smelly to begin with.
One of the three bird smells came from the mate of the bird being tested.
These results revealed that the birds could pick out the specific smells of their partners and that they preferred their mates' smells over other birds' smells.

 Prion Diseases
Abnormal prion proteins are little understood disease agents involved in causing horrific brain-wasting diseases such as Creutzfeldt-Jacob disease in people, mad cow disease in cattle and chronic wasting disease in deer and elk.
Researchers knew that prions, the misfolded proteins that cause mad cow disease and other brain disorders, were killing off a class of important brain cells in a transgenic mouse model.
Furthermore, the study finds that the infectious prion proteins, also known as prions, cross the normally stringent intestinal barrier by riding piggyback on ferritin, a protein normally absorbed by the intestine and abundantly present in a typical meat dish.
