Ubiquitin and the Molecular Pathology of Neurodegenerative Diseases

Abstract
Ubiquitin is an important molecule which now appears central to several pathological cellular processesl. There is a close association between ubiquitin-protein conjugates, cytoskeletal abnormalities as well as with the endosome-lysosome system in cells. This overview concentrates on the involvement of the ubiquitin system in diseases of the nervous system, an importance which has been reinforced by recent molecular insights into neurodegenerative processes.
