The proteasome is a construct in cells that shreds damaged, misfolded, or unwanted proteins, reducing them to component parts that can be reused. It is a part of the ubuiquitin-proteasome system: molecules to be destroyed are tagged with ubiquitin, and drawn into a proteasome for recycling. Greater proteasome activity is thought to be a good thing, improving cell function. This is of particular relevance to aging, as proteasomal function declines with age, contributing to faltering cell and tissue function, particularly in the long-lived cells of the nervous system.
