The phytohormone auxin is of fundamental importance in plant development. Since the identification of auxin as a plant growth substance, auxin transport has drawn considerable research attention. Intercellular (polar) auxin transport contributes to its graded distribution in cell files or entire organs and allows for dynamic, environmentally controlled

Considerable effort over the past three decades has allowed the identification of the protein families that control the cellular machinery responsible for intracellular transport within eukaryotic cells. These proteins are estimated to represent about 10–20% of the human “proteome.” The complexity of intracellular transport makes useful the development

Regulation of intracellular membrane transport
Current Opinion in Cell Biology, 1992A number of proteins that are necessary for membrane transport have been identified using cell-free assays and yeast genetics. Although our knowledge of transport mechanisms remains limited, common themes are clearly emerging. In particular, specific GTP-binding proteins appear to be involved, not only at all steps of membrane traffic but also at more ...

Membrane tethering in intracellular transport
Current Opinion in Cell Biology, 1999Studies of various membrane trafficking steps over the past year indicate that membranes are tethered together prior to the interaction of v-SNAREs and t-SNAREs across the membrane junction. The tethering proteins identified to date are quite large, being either fibrous proteins or multimeric protein complexes.

Intracellular sterol transport and distribution
Current Opinion in Cell Biology, 2006Sterols are important components of many biological membranes, and changes in sterol levels can have dramatic effects on membrane properties. Sterols are transported rapidly between cellular organelles by vesicular and nonvesicular processes. Recent studies have identified transmembrane proteins that facilitate the removal of sterols from membranes as ...

Intracellular cholesterol transport
1995Intracellular trafficking of cholesterol and various other sterols is important for cholesterol homeostasis of cells and the entire organism. Understanding the mechanisms involved in regulated, target-specific intracellular cholesterol transport is of great impact for understanding the pathogenesis of atherosclerosis and a number of inherited lipid ...

Intracellular Transport of Pancreatic Enzymes
Scandinavian Journal of Gastroenterology, 1996Most pancreatic secretory proteins are packaged within the trans-Golgi network into zymogen granules, which are secreted in a regulated manner by exocytosis. But others enter alternative, constitutive-like pathways directed towards both apical and basolateral membranes.

Cytoskeletal elements and intracellular transport
Journal of Cellular Biochemistry, 2007AbstractRecent advances in the understanding of the functions of various components of the cytoskeleton indicate that, besides serving a structural role, the cytoskeletal elements may regulate the transport of several proteins in the cell. Studies reveal that there are co‐operative interactions between the actin and microtubule cytoskeletons including ...

Intracellular Structure and Nucleocytoplasmic Transport
1996Intracellular movement of any solute or particle accords with one of two general schemes: either it takes place predominantly in the solution phase or it occurs by dynamic interactions with solid-state structures. If nucleocytoplasmic exchanges of macromolecules and complexes are predominantly solution-phase processes, i.e., if the former ...
