[Large and small G proteins in vesicular transport].
Annales d'endocrinologie, 1996The movement of proteins between compartments of the exocytic and endocytic pathways of eukaryotic cells is mediated by carrier vesicles. They bud from a donor compartment and are targetted to and fuse with the acceptor compartment. GTPases, proteins which bind and hydrolyze GTP, play key roles in the regulation of this vesicular protein transport ...

Rab7 is a critical mediator in vesicular transport of tyrosinase‐related protein 1 in melanocytes
The Journal of Dermatology, 2010AbstractHow melanosomal proteins such as enzymic proteins (tyrosinase and tyrosinase‐related proteins, Tyrps) and structural protein (gp100) are transported from Golgi to melanosomal compartments is not yet fully understood. A number of small GTPases have been found to be associated with melanosomes and we have identified one of them, Rab7, a regulator

Loss of Striatal Vesicular Monoamine Transporter Protein (VMAT2) in Human Cocaine Users
American Journal of Psychiatry, 2003The hypothesis that human cocaine users lose vesicular monoamine transporter (VMAT2) protein was tested in striatal samples from cocaine users and age-, sex-, and postmortem interval-matched comparison subjects.Striatal samples were retrieved at autopsy; immunoblot assays were then performed by using a highly specific VMAT2 antibody.

Proteins and vesicular transport in capillary endothelium.
Federation proceedings, 1983Plasma proteins interact with vascular endothelium in such a way as to render it less permeable to other macromolecules. Evidence from a variety of sources indicates that this may result from interaction of the circulating macromolecules with the negatively charged glycoprotein layer on the surface of endothelial cells, and that this layer may be ...

Small G Proteins: Arf Family GTPases in Vesicular Transport
2014Small GTP-binding proteins of the ADP-ribosylation factor (Arf) family are key components of trafficking vesicles. In the past three decades a number of vesicular carriers, whose formation depends on members of the Arf family were identified, and general molecular mechanisms how these transport carriers form and operate were established.

G Protein Regulation of Vesicular Transport Through the Exocytic Pathway
1993A central problem in cell biology is to understand the molecular basis for the transport of itinerant soluble and membrane-associated macromolecules through multiple compartments of the exocytic and endocytic pathways of eukaryotic cells. Transport involves a multiplicity of components which facilitate the formation of coat protein complexes leading to

Mediation of the Attachment or Fusion Step in Vesicular Transport by the GTP-Binding Ypt1 Protein
Science, 1991The function of the guanosine triphosphate (GTP)-binding protein Ypt1 in regulating vesicular traffic was studied in a cell-free system that reconstitutes transport from the endoplasmic reticulum to the Golgi. Blocking the Ypt1 protein activity resulted in accumulation of vesicles that act as an intermediate passing between the two compartments.
