In its native state, it forms a stable homodimer and binds copper and zinc. Mutations in SOD1 cause familial Amyotrophic Lateral Sclerosis (ALS). Among them, the A4V mutation (Alanine → Valine at residue 4) leads to one of the most aggressive forms of the disease. The mutation subtly destabilizes the N-terminus, perturbs folding energetics, and promotes toxic aggregation. Your challenge: a. Design short peptides that bind mutant SOD1. b. Then decide which ones are worth advancing toward therapy.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/srinidhi-vasan/homework/week-05-protein-design-part-ii/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
