Role of Proteases in the Pathophysiology of Neurodegenerative Diseases by Abel Lajtha
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.| SKU | NLS9781441933607 |

"I was paying $11.99/month for Kindle Unlimited but realized I was renting books, not owning them. Bought this PDF and it's mine forever. Never going back to Kindle."
"Switched from Kindle to these PDFs. Same book, but I actually OWN it now. No monthly fees, no app required. Worth every penny."
"Kindle Unlimited kept raising prices. This is a one-time purchase and the file is permanently on my iPad. Best decision I've made for my reading habit."
"I compared Kindle vs this store. Kindle is cheaper monthly but you don't own anything. Here I paid once and the PDF is mine for life. Highly recommend."
"Left Kindle behind after they removed a book I was reading mid-series. With this PDF, nobody can take it away from me. True ownership feels good."
"Was skeptical about paying $18.95 when Kindle shows $3.99, but then I did the math — Kindle Unlimited is $143/year! This is way better value long term."
"Love that I can read this on any device without installing the Kindle app. The PDF works on my laptop, phone, and tablet seamlessly. So much freedom."
"My Kindle subscription was getting expensive. Switched to buying PDFs here and I'm saving money while actually building a permanent digital library I control."
