...Jinae N. Roa; Martin Tresguerres ABSTRACT Na + /K + -ATPase (NKA)- and vacuolar H + -ATPase (VHA)-rich cells in shark gills secrete excess acid and base, respectively, to seawater to maintain blood acid–base homeostasis. Both cell types are rich in mitochondria, indicating high ATP demand; however...

... the temperature interactions of a major cytosolic molecular chaperone, Hsc70, from the eurythermal marine goby Gillichthys mirabilis . Using in vitro assays, we measured the intrinsic activity, unfolded-protein-stimulated activity, temperature sensitivity and heat stability of the ATPase activity of native Hsc70...
