7.2.2.3 | additional information | Cer acts as a potent physiological modulator of the Na+-ATPase, participating in a regulatory network in kidney cells and counteracting the stimulatory effect of PKA via PKCzeta | Sus scrofa |
7.2.2.3 | physiological function | the Na+-ATPase is involved in Na+ reabsorption in the kidney. Ouabain-insensitive Na+-ATPase is considered the fine tuner of cytosolic Na+, the selective key roles of ceramide under Na+-induced osmotic stress | Sus scrofa |
