Beschreibung:
Cellular membranes act as signaling platforms and control solute transport. Membrane receptors, transporters, and enzymes communicate with intracellular processes through protein-protein interactions. Using a split-ubiquitin yeast two-hybrid screen that covers a test-space of 6.4 x 10(6) pairs, we identified 12,102 membrane/signaling protein interactions from Arabidopsis. Besides confirmation of expected interactions such as heterotrimeric G protein subunit interactions and aquaporin oligomerization, 〉99% of the interactions were previously unknown. Interactions were confirmed at a rate of 32% in orthogonal in planta split-green flourescent protein interaction assays, which was statistically indistinguishable from the confirmation rate for known interactions collected from literature (38%). Regulatory associations in membrane protein trafficking, turnover, and phosphorylation include regulation of potassium channel activity through abscisic acid signaling, transporter activity by a WNK kinase, and a brassinolide receptor kinase by trafficking-related proteins. These examples underscore the utility of the membrane/signaling protein interaction network for gene discovery and hypothesis generation in plants and other organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, Alexander M -- Xuan, Yuanhu -- Xu, Meng -- Wang, Rui-Sheng -- Ho, Cheng-Hsun -- Lalonde, Sylvie -- You, Chang Hun -- Sardi, Maria I -- Parsa, Saman A -- Smith-Valle, Erika -- Su, Tianying -- Frazer, Keith A -- Pilot, Guillaume -- Pratelli, Rejane -- Grossmann, Guido -- Acharya, Biswa R -- Hu, Heng-Cheng -- Engineer, Cawas -- Villiers, Florent -- Ju, Chuanli -- Takeda, Kouji -- Su, Zhao -- Dong, Qunfeng -- Assmann, Sarah M -- Chen, Jin -- Kwak, June M -- Schroeder, Julian I -- Albert, Reka -- Rhee, Seung Y -- Frommer, Wolf B -- New York, N.Y. -- Science. 2014 May 16;344(6185):711-6. doi: 10.1126/science.1251358.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution for Science, CA 94305, USA. ; Department of Physics, Pennsylvania State University, University Park, PA 16802, USA. ; Department of Plant Biology, Carnegie Institution for Science, CA 94305, USA.
