Zinc, which is involved in the structure of all enzyme classes, is a micro nutrient element and necessary for growth and development. The ability of zinc to function without causing toxic effects is depends on the protection of its homeostasis. Zinc transporter proteins are responsible for keeping zinc at certain concentrations.

Bicarbonate transport proteins
Biochemistry and Cell Biology, 2002Bicarbonate is not freely permeable to membranes. Yet, bicarbonate must be moved across membranes, as part of CO2 metabolism and to regulate cell pH. Mammalian cells ubiquitously express bicarbonate transport proteins to facilitate the transmembrane bicarbonate flux.

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.

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.

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 ...

Membrane Transport of Proteins
Nature New Biology, 1972FACILITATED diffusion of small organic molecules across cell membranes is thought to be carrier-mediated in part because the process displays reaction kinetics. Models describing carrier transport assume that the transported molecule is associated with the membrane, reacting presumably with membrane proteins, and is then moved across the barrier.

Protein Transport into Chloroplasts
Annual Review of Plant Biology, 2010Most proteins in chloroplasts are encoded by the nuclear genome and synthesized as precursors with N-terminal targeting signals called transit peptides. Novel machinery has evolved to specifically import these proteins from the cytosol into chloroplasts.

Thyroid Hormone Transport Proteins
Clinics in Laboratory Medicine, 1993TBG, TTR, and albumin are quantitatively the most important thyroid hormone binding proteins in humans. Only a minute fraction of T3 and T4 circulates unbound, but it is this free hormone that is metabolically active at the tissue level, and, therefore, responsible for thyroid status. Inherited or acquired variations in the concentration or affinity of

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
