Protein transport across the small intestine in food allergy.
Molecular Nutrition & Food Research, 2014In view of the imminent deficiency of protein sources for human consumption in the near future, new protein sources need to be identified. However, safety issues such as the risk of allergenicity are often a bottleneck, due to the absence of predictive ...

Bicarbonate transport proteins
Biochemistry and Cell Biology, 2002Bicarbonate is not freely permeable to membranes. Yet, bicarbonate must be moved across membranes, as part of CO2metabolism and to regulate cell pH. Mammalian cells ubiquitously express bicarbonate transport proteins to facilitate the transmembrane bicarbonate flux.

Regulation of membrane protein transport by ubiquitin and ubiquitin-binding proteins.
Annual Review of Cell and Developmental Biology, 2003Ubiquitin regulates protein transport between membrane compartments by serving as a sorting signal on protein cargo and by controlling the activity of trafficking machinery.

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 ...

Transport of Proteins into Mitochondria
1984There is still much that is obscure concerning the transport of proteins into or through the mitochondrial membrane systems. In addition, as pointed out previously, it is unlikely that the details of the process are the same for proteins destined for different compartments of the organelle. A brief summary of the process for matrix proteins might be as

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.

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.

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 ...

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.

Motor proteins transporting cargos
The European Physical Journal E, 2005Processive motor proteins such as kinesin and myosin-V are enzymes that use the energy of ATP hydrolysis to travel along polar cytoskeletal filaments. One of the functions of these proteins is the transport of vesicles and protein complexes that are linked to the light chains of the motors. Modeling the light chain by a linear elastic spring, and using
