Description:
Amyloids are highly organized cross-beta-sheet-rich protein or peptide aggregates that are associated with pathological conditions including Alzheimer's disease and type II diabetes. However, amyloids may also have a normal biological function, as demonstrated by fungal prions, which are involved in prion replication, and the amyloid protein Pmel17, which is involved in mammalian skin pigmentation. We found that peptide and protein hormones in secretory granules of the endocrine system are stored in an amyloid-like cross-beta-sheet-rich conformation. Thus, functional amyloids in the pituitary and other organs can contribute to normal cell and tissue physiology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2865899/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2865899/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maji, Samir K -- Perrin, Marilyn H -- Sawaya, Michael R -- Jessberger, Sebastian -- Vadodaria, Krishna -- Rissman, Robert A -- Singru, Praful S -- Nilsson, K Peter R -- Simon, Rozalyn -- Schubert, David -- Eisenberg, David -- Rivier, Jean -- Sawchenko, Paul -- Vale, Wylie -- Riek, Roland -- P01 DK026741/DK/NIDDK NIH HHS/ -- P01 DK026741-29/DK/NIDDK NIH HHS/ -- P01 DK026741-30/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 17;325(5938):328-32. doi: 10.1126/science.1173155.
