Comparative Activity of ADP-ribosylation Factor Family Members in the Early Steps of Coated Vesicle Formation on Rat Liver Golgi Membranes* (Received for publication, September 10, 1996, and in revised form, December 5, 1996) Jennifer Ostrom Liang‡ and Stuart Kornfeld§ From the Department of Medicine, Washington University, St. Louis, Missouri 63110 We have compared the abilities of mammalian ADP- guanine nucleotide exchange factor (GEF) that catalyzes the ribosylation factors (ARFs) 1, 5, and 6 and Saccharomy- exchange of GTP for GDP on ARF (6–8). Once it has bound ces cerevisiae ARF2 to serve as substrates for the rat GTP or its slowly hydrolyzable analog, GTPgS, ARF facilitates liver Golgi membrane guanine nucleotide exchange fac- the recruitment of the heterotetrameric AP-1 adaptor complex tor and to initiate the formation of clathrin- and and clathrin onto the Golgi membranes (2, 3). COPI-coated coatomer protein (COP) I-coated vesicles on these mem- vesicle formation also proceeds following the initial recruit- branes. While Golgi membranes stimulated the ex- ment of ARF onto the Golgi TI - Comparative Activity of ADP-ribosylation Factor Family Members in the Early Steps of Coated Vesicle Formation on Rat Liver Golgi Membranes JF - Journal of Biological Chemistry DO - 10.1074/jbc.272.7.4141 DA - 1997-02-01 UR - https://www.deepdyve.com/lp/unpaywall/comparative-activity-of-adp-ribosylation-factor-family-members-in-the-9Q7oe7GJkh DP - DeepDyve ER -
