Springer Role Of Proteases In The Pathophysiology Of Neurodegenerative Diseases 2001 Edition by Abel Lajtha Naren L. Banik

Researchers seeking problems that offer more hope of success often avoid subjects that seem to be difficult to approach experimentally or subjects for which experimental results are difficult to interpret. The breakdown part of protein turnover in vivo particularly in nervous tissue was such a subject in the past - it was difficult to measure and difficult to explore the mechanisms involved. For factors that influence protein metabolism it was thought that protein content function and distribution are controlled only by the synthetic mechanisms that can supply the needed specificity and response to stimuli. The role of breakdown was thought to be only a general metabolic digestion elimination of excess polypeptides. We now know that the role of breakdown is much more complex: it has multiple functions it is coupled to turnover and it can affect protein composition function and synthesis. In addition to eliminating abnormal proteins breakdown has many modulatory functions: it serves to activate and inactivate enzymes modulate membrane function alter receptor channel properties affect transcription and cell cycle form active peptides and much more. The hydrolysis of peptide bonds often involves multiple steps many enzymes and cycles (such as ubiquination) and often requires the activity of enzyme complexes. Their activation modification and inactivation can thus play an important role in biological functions with numerous families of proteases participating. The specific role of each remains to be elucidated. Table of contents : 1. The Role of Proteolytic Enzymes in Autoimmune Demyelinating Diseases: An Update; M.E. Smith. 2.
