Título: | Osmotin is a homolog of mammalian adiponectin and controls apoptosis in yeast through a homolog of mammalian adiponectin receptor |
Autor: | Narasimhan, Meena L.; Bressan, Ray A.; Coca, María CSIC ORCID; Pardo, José M. CSIC ORCID | Fecha de publicación: | 21-ene-2005 | Editor: | Elsevier | Citación: | Molecular Cell 17 (2): 171-180 (2005) | Resumen: | The antifungal activity of the PR-5 family of plant defense proteins has been suspected to involve specific plasma membrane component(s) of the fungal target. Osmotin is a tobacco PR-5 family protein that induces apoptosis in the yeast Saccharomyces cerevisiae. We show here that the protein encoded by ORE20/PHO36 (YOL002c), a seven transmembrane domain receptor-like polypeptide that regulates lipid and phosphate metabolism, is an osmotin binding plasma membrane protein that is required for full sensitivity to osmotin. PHO36 functions upstream of RAS2 in the osmotin-induced apoptotic pathway. The mammalian homolog of PHO36 is a receptor for the hormone adiponectin and regulates cellular lipid and sugar metabolism. Osmotin and adiponectin, the corresponding “receptor” binding proteins, do not share sequence similarity. However, the β barrel domain of both proteins can be overlapped, and osmotin, like adiponectin, activates AMP kinase in C2C12 myocytes via adiponectin receptors. | Descripción: | 10 pages, 5 figures, 44 references.
