Sodium serves as the driving ion in many (but not all) secondary active transporters located in the plasma membrane of various cells. This is appropriate as there is a steep Na+ concentration gradient across the plasma membrane that is maintained by the Na+/K+/ATPase. In mammals, the ...
Lateral movement, either via diffusion or active transport, is quite distinct from currently studied pathways of ciliary protein transport in mammals, which emphasize directed trafficking of Golgi-derived vesicles to the base of the cilium. We anticipate that this alternative route will be used by ...
Vitamin C (L-ascorbic acid) is an essential nutrient for human health, and its deficiency has long been known to cause scurvy. Sodium-dependent vitamin C transporters (SVCTs) are responsible for vitamin C uptake and tissue distribution in mammals. Here, we present cryogenic electron microscopy ...

Sulfate is the fourth most abundant anion in mammals and serves as an important macronutrient, representing a major source of the essential element sulfur. The intracellular concentration of sulfate anion is primarily regulated by sulfate transporters since passive transport of hydrophilic anions through ...
exchanged during normal breathing. The TIDAL VOLUME is the volume of air exchanged during normal breathing. This is the volume of air in each breath in & out. Usually around dm 3 per breath at rest. This is the volume of air in each breath in & out. Usually around dm 3 per breath ...
. In the final section, the effects of PCBs on populations are discussed, and some population declines in wild birds and mammals to which PCBs have been, or may be, contributing factors are presented. View chapterExplore book Environmental Geochemistry...
However, it is known that a conserved region at the N-terminus of GM130 binds directly to p115, a protein implicated in the tethering of vesicles in both yeast and mammals [49–51]. This suggests that at least part of GM130’s activity resides in a conserved N-terminal region even if...

Pelagic red crabs (Pleuroncodes planipes) are shallow-living, swimming squat lobsters with omnivorous diets, and are widely consumed by tuna, squid, sea birds, sharks, sea turtles, and marine mammals (e.g.29,30). Pelagic red crabs have both pelagic and benthic life stages and are ...
