Descriptions

Small GTPases couple their GDP/GTP structural cycle to cytosol/membrane alternation to function as versatile molecular switches in the cell. Membrane localization of their active, GTP-bound form is pivotal to their ability to propagate information, and this requires their post-translational modification by lipids.<br>Arf GTPases are modified by a myristate attached to their N-terminus, which is shielded by intramolecular interactions in their inactive state. The myristoylated N-terminus of Arf is autoinhibitory in solution and is displaced by membranes, priming Arf GTPases for activation by their GEFs. Replacement of the N-terminal myristate by a 6xHis-tag preserves autoinhibition, representing that membranes unlock the N-terminal region to facilitate subsequent activation.

5 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
Golgi membrane The lipid bilayer surrounding any of the compartments of the Golgi apparatus.
lysosomal membrane The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

7 GO annotations of molecular function

Name Definition
GDP binding Binding to GDP, guanosine 5'-diphosphate.
GTP binding Binding to GTP, guanosine triphosphate.
GTPase activity Catalysis of the reaction
identical protein binding Binding to an identical protein or proteins.
ubiquitin protein ligase activity Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond
ubiquitin-protein transferase activity Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
zinc ion binding Binding to a zinc ion (Zn).

5 GO annotations of biological process

Name Definition
intracellular protein transport The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.
positive regulation of autophagy Any process that activates, maintains or increases the rate of autophagy. Autophagy is the process in which cells digest parts of their own cytoplasm.
positive regulation of protein modification process Any process that activates or increases the frequency, rate or extent of the covalent alteration of one or more amino acid residues within a protein.
protein ubiquitination The process in which one or more ubiquitin groups are added to a protein.
vesicle-mediated transport A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
