Book Synopsis GTPases Regulating Membrane Targeting and Fusion by : W. E. Balch
Download or read book GTPases Regulating Membrane Targeting and Fusion written by W. E. Balch and published by Gulf Professional Publishing. This book was released on 2005-12-13 with total page 946 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rab GTPases now comprise a family of >63 members. They are emerging as the key hub element controlling the membrane architecture of eukaryotic cells. They are intimately involved in vesicle targeting and fusion in both the endocytic and exocytic pathways and direct the assembly and disassembly of protein complexes that include regulators (GEFs and GAPs), effectors (tethers/motors) and fusion components (SNAREs) that control membrane targeting and fusion. During the last 3 years the field has virtually exploded with the identification and characterization of many new Rab proteins and their effectors. Our understanding of how Rab GTPases control membrane function remains at its infancy. This volume of Methods in Enzymology, GTPases Regulating Membrane Targeting and Fusion, provides a wealth of new concepts, approaches and tools to study Rab proteins in the test tube and in living cells that will be of strong benefit to both established laboratories and new investigators in the field to elucidate Rab GTPase function in cellular development, differentiation and proliferation. Comprehensive overview of Rab GTPase phylogeny and systems biology Identification and characterization of Rab GEFs, GAPs and effectors General methodologies to study Rab GTPase function in vitro and in vivo using biochemical, molecular and microscopy approaches

Book Synopsis Regulators and Effectors of Small GTPases: Ras Family by :
Download or read book Regulators and Effectors of Small GTPases: Ras Family written by and published by Elsevier. This book was released on 2006-06-07 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ras superfamily (>150 human members) encompasses Ras GTPases involved in cell proliferation, Rho GTPases involved in regulating the cytoskeleton, Rab GTPases involved in membrane targeting/fusion and a group of GTPases including Sar1, Arf, Arl and dynamin involved in vesicle budding/fission. These GTPases act as molecular switches and their activities are controlled by a large number of regulatory molecules that affect either GTP loading (guanine nucleotide exchange factors or GEFs) or GTP hydrolysis (GTPase activating proteins or GAPs). In their active state, they interact with a continually increasing, functionally complex array of downstream effectors. Since the last Methods in Enzymology volume on this topic in 2000, the study of Ras Family GTPases has witnessed a plethora of new directions and trends. With regards to the founding member of the Ras superfamily, the study of Ras in oncogenesis has seen the development and application of more advanced model cell culture and animal systems. The discovery of mutationally activated B-Raf in human cancers has injected renewed interest in this classical effector pathway of Ras. - Includes a database for Ras family proteins and their effectors and regulators - Complimentary to volume 406 coverage of the Rho family - Over 150 international contributors

Book Synopsis Rab GTPase-activating Proteins at the Golgi:endosome Interface by : Ryan Michael Nottingham
Download or read book Rab GTPase-activating Proteins at the Golgi:endosome Interface written by Ryan Michael Nottingham and published by Stanford University. This book was released on 2010 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rab GTPases are master regulators of membrane trafficking in eukaryotic cells. With GTP bound, they regulate trafficking by recruiting effectors to specific membrane-bound compartments. GTPase-activating proteins (GAPs) stimulate a Rab's intrinsic rate of GTP hydrolysis, thus inactivating the Rab by converting bound GTP to GDP. Regulation of Rab proteins links the formation and breakdown of sequential, Rab-regulated membrane domains in the secretory and endocytic pathways. This thesis presents the characterization of a novel RabGAP, RUTBC1. RUTBC1 binds Rab9 in vitro and in cells through interactions with its N-terminus. Overexpression of RUTBC1 only slightly disrupts MPR trafficking and RUTBC1 does not function as a GAP for Rab9. In vitro biochemical screening of Rab proteins revealed that RUTBC1 has GAP activity toward Rab33b and Rab32. These data suggest that RUTBC1 might function to link inactivation of these Rabs in relation to a Rab9 microdomain, in support of the existence of a Rab cascade at the interface between the Golgi apparatus and endosomes. Depletion of RUTBC1 unexpectedly led to concomitant depletion of Atg16L1. Atg16L1 has an established and essential role in macroautophagy, a highly conserved cellular recycling process. Overexpression of Atg16L1 caused the formation of large puncta in the cytoplasm, which are also labeled by endogenous RUTBC1 and may represent autophagosomes. Atg16L1 is a known Rab33b effector, suggesting that Rab33b, RUTBC1 and Atg16L1 function together to regulate autophagosome formation. Finally, RUTBC2, which is highly related to RUTBC1, also binds specifically to Rab9. In vitro biochemical screening for RUTBC2's Rab substrates showed that RUTBC2 had highest GAP activity toward Rab34 and Rab36, two very similar Rabs thought to play a role in secretion. The difference in substrate specificity between RUTBC1 and RUTBC2 further exemplifies the highly complex integration of diverse membrane trafficking pathways in mammalian cells.
