Arf family GTP loading is activated by, and generates, positive membrane curvatureRichard Lundmark
MRC Laboratory of Molecular Biology, Hills Road, Cambridge, CB2 0QH, UK
Biochem J 414:189-94. 2008..Arf1 and Arf6 were shown to load GTP in a membrane-curvature-dependent manner and stabilize, or further facilitate, changes in membrane curvature through the insertion of an amphipathic helix...
Driving membrane curvature in clathrin-dependent and clathrin-independent endocytosisRichard Lundmark
Department of Medical Biochemistry and Biophysics, Umea University, 901 87 Umea, Sweden
Semin Cell Dev Biol 21:363-70. 2010..We will discuss these principles and their implications, focusing on clathrin-dependent and -independent carrier formation and the proteins involved in the respective pathways...
GRAF1-dependent endocytosisGary J Doherty
MRC Laboratory of Molecular Biology, Hills Road, Cambridge, UK
Biochem Soc Trans 37:1061-5. 2009....
The GTPase-activating protein GRAF1 regulates the CLIC/GEEC endocytic pathwayRichard Lundmark
Medical Research Council, Laboratory of Molecular Biology, Hills Road, Cambridge, CB2 0QH, UK
Curr Biol 18:1802-8. 2008....
Regulated membrane recruitment of dynamin-2 mediated by sorting nexin 9Richard Lundmark
Department of Medical Biochemistry and Biophysics, Umea University, S 901 87 Umea, Sweden
J Biol Chem 279:42694-702. 2004..The results suggest that SNX9-dependent recruitment of Dyn2 to the membrane is regulated by an interaction between SNX9 and aldolase...
The endocytic protein GRAF1 is directed to cell-matrix adhesion sites and regulates cell spreadingGary J Doherty
MRC Laboratory of Molecular Biology, Cambridge CB2 0QH, United Kingdom
Mol Biol Cell 22:4380-9. 2011..We propose that GRAF1 remodels membrane microdomains at adhesion sites into endocytic carriers, facilitating membrane turnover during cell morphological changes...
EHD2 regulates caveolar dynamics via ATP-driven targeting and oligomerizationBjörn Morén
Medical Biochemistry and Biophysics, Laboratory for Molecular Infection Medicine, Sweden, Umea University, Umea, Sweden
Mol Biol Cell 23:1316-29. 2012..Thus, following the identification of caveolin and cavins, EHD2 constitutes a third structural component of caveolae involved in controlling the stability and turnover of this organelle...
Expression and properties of sorting nexin 9 in dynamin-mediated endocytosisRichard Lundmark
Department of Medical Biochemistry and Biophysics, , Sweden
Methods Enzymol 404:545-56. 2005..Assays are presented to investigate the requirements for SNX9-dependent membrane recruitment of dynamin in vitro and in vivo...
SNX18 is an SNX9 paralog that acts as a membrane tubulator in AP-1-positive endosomal traffickingKarin Håberg
Department of Medical Biochemistry and Biophysics, Umea University, Umea, Sweden
J Cell Sci 121:1495-505. 2008..The results indicate that SNX9-family members make up discrete membrane-scission units together with dynamin, and suggest that SNX18 mediates budding of carriers for AP-1-positive endosomal trafficking...
Sorting nexin 9 participates in clathrin-mediated endocytosis through interactions with the core componentsRichard Lundmark
Department of Medical Biochemistry and Biophysics, Umea University, S 901 87 Umea, Sweden
J Biol Chem 278:46772-81. 2003..Overexpression in both K562 and HeLa cells of truncated forms of SNX9 interfered with the uptake of transferrin, consistent with a role of SNX9 in endocytosis...
SNX9 - a prelude to vesicle releaseRichard Lundmark
Department of Medical Biochemistry and Biophysics, Umea University, S 90187 Umea, Sweden
J Cell Sci 122:5-11. 2009..In this Commentary, we summarize several aspects of SNX9 structure and function in the context of membrane remodeling, discuss its interplay with various interaction partners and present a model of how SNX9 might work in endocytosis...
The beta-appendages of the four adaptor-protein (AP) complexes: structure and binding properties, and identification of sorting nexin 9 as an accessory protein to AP-2Richard Lundmark
Department of Medical Biochemistry and Biophysics, Umea University, S 901 87 Umea, Sweden
Biochem J 362:597-607. 2002..SNX9, which contains a phox and an Src homology 3 domain, was found in large complexes and was at least partially associated with AP-2 in the cytosol. SNX9 may function to assist AP-2 in its role at the plasma membrane...
The PX-BAR membrane-remodeling unit of sorting nexin 9Olena Pylypenko
Department of Physical Biochemistry, Max Planck Institute for Molecular Physiology, Dortmund, Germany
EMBO J 26:4788-800. 2007..The study provides insights into the SNX9-induced membrane modulation mechanism...
