The abnormal prion is a version of the normal protein that has run amok.

By this method, selected normal proteins are removed from the cell in response to specific signals.

Prions are normal proteins found on the surface of cells throughout the body.

Two of the three events theoretically would produce truncated proteins with little similarity to the normal protein.

PrP is a normal protein found on the membranes of cells.

By correcting these flaws, it will leave a normal protein, ready to do the work of the cell.

The prions cause normal proteins of the sheep to fold into the wrong shape.

One was an artificial string of 20 glutamines, like those found in many normal proteins.

The normal protein is found on the surface of brain cells but its function is unknown.

Then, in a process that is still not understood, they force the normal proteins to change their shapes and become like the abnormal ones.
