Beschreibung: Adiponectin stimulation of its receptors, AdipoR1 and AdipoR2, increases the activities of 5' AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor (PPAR), respectively, thereby contributing to healthy longevity as key anti-diabetic molecules. AdipoR1 and AdipoR2 were predicted to contain seven transmembrane helices with the opposite topology to G-protein-coupled receptors. Here we report the crystal structures of human AdipoR1 and AdipoR2 at 2.9 and 2.4 A resolution, respectively, which represent a novel class of receptor structure. The seven-transmembrane helices, conformationally distinct from those of G-protein-coupled receptors, enclose a large cavity where three conserved histidine residues coordinate a zinc ion. The zinc-binding structure may have a role in the adiponectin-stimulated AMPK phosphorylation and UCP2 upregulation. Adiponectin may broadly interact with the extracellular face, rather than the carboxy-terminal tail, of the receptors. The present information will facilitate the understanding of novel structure-function relationships and the development and optimization of AdipoR agonists for the treatment of obesity-related diseases, such as type 2 diabetes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4477036/" 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/PMC4477036/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanabe, Hiroaki -- Fujii, Yoshifumi -- Okada-Iwabu, Miki -- Iwabu, Masato -- Nakamura, Yoshihiro -- Hosaka, Toshiaki -- Motoyama, Kanna -- Ikeda, Mariko -- Wakiyama, Motoaki -- Terada, Takaho -- Ohsawa, Noboru -- Hato, Masakatsu -- Ogasawara, Satoshi -- Hino, Tomoya -- Murata, Takeshi -- Iwata, So -- Hirata, Kunio -- Kawano, Yoshiaki -- Yamamoto, Masaki -- Kimura-Someya, Tomomi -- Shirouzu, Mikako -- Yamauchi, Toshimasa -- Kadowaki, Takashi -- Yokoyama, Shigeyuki -- 062164/Z/00/Z/Wellcome Trust/United Kingdom -- 089809/Wellcome Trust/United Kingdom -- BB/G02325/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G023425/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2015 Apr 16;520(7547):312-6. doi: 10.1038/nature14301.
