Transport of proteins into chloroplasts
Photosynthesis Research, 1988The import of cytoplasmically synthesized proteins into chloroplasts involves an interaction between at least two components; the precursor protein, and the import apparatus in the chloroplast envelope membrane. This review summarizes the information available about each of these components.

Transport through lipids and aquaporins is osmotic and entirely driven by the difference in osmotic pressure. Water transport in cotransporters and uniporters is different: Water can be cotransported, energized by coupling to the substrate flux by a mechanism closely associated with protein.

Transport of proteins into mitochondria
2007Most mitochondrial proteins are nuclear-encoded and synthesised as preproteins on polysomes in the cytosol. They must be targeted to and translocated into mitochondria. Newly synthesised preproteins interact with cytosolic factors until their recognition by receptors on the surface of mitochondria.

The plasma membrane of epithelial cells and hepatocytes is divided into two separate membrane compartments, the apical and the basolateral domain. This polarity is maintained by intracellular machinery that directs newly synthesized material into the correct target membrane.

Glycosylation and protein transport
Essays in Biochemistry, 2000Transport along the secretory pathway is largely signal-mediated. Proteins in the secretory pathway can be covalently modified with various carbohydrate structures, most commonly O-glycans, N-glycans and/or proteoglycans. Carbohydrate modifications can change the physical properties of proteins or can function as specific recognition epitopes ...

Nucleocytoplasmic transport of proteins
Biochemistry (Moscow), 2007In eukaryotic cells, the movement of macromolecules between the nucleus and cytoplasm occurs through the nuclear pore complex (NPC)--a large protein complex spanning the nuclear envelope. The nuclear transport of proteins is usually mediated by a family of transport receptors known as karyopherins.

Publisher Summary This chapter discusses the process of nuclear protein transport. Work on the mechanism of nuclear transport has led to a fairly detailed understanding of how proteins are targeted for import or export. This work has changed the way in which researchers need to think about potential transport mechanisms for their own protein of ...

The relative constancy of the internal environment of the cell is maintained by a variety of transport systems which are located within the membrane. These transport systems serve to regulate the entrance and exit of various solutes concerned with the metabolic activity of the cell.

PROTEINS OF AXONAL TRANSPORT: INTERACTION OF RAPIDLY TRANSPORTED PROTEINS WITH LECTINS
Journal of Neurochemistry, 1979Abstract—Rapidly transported fucose‐labelled glycoproteins from the optic system of the rabbit were solubilised with the non‐ionic detergent Berol 172.The major labelled components were bound to wheat germ agglutinin or Concanavalin A coupled to Sepharose but not to other lectins or glycoproteins.

Membrane transport proteins: not just for transport anymore
American Journal of Physiology-Renal Physiology, 2006digitalis glucosides have been used for their cardiotonic properties for several centuries. It was not until the 1950s that the molecular target of these compounds was identified as the Na-K-ATPase.
