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.

Name Definition
Golgi apparatus A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

2 GO annotations of molecular function

Name Definition
GTP binding Binding to GTP, guanosine triphosphate.
GTPase activity Catalysis of the reaction

2 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.
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.
