Renal Anemia Model Mouse Established by Transgenic Rescue with an Erythropoietin Gene Lacking Kidney-Specific Regulatory Elements.

abstract：:The mammalian target of rapamycin (mTOR) is a Ser/Thr (S/T) protein kinase, which controls mRNA translation initiation by modulating phosphorylation of the translational regulators PHAS-I and p70(S6K). Here we show that in vitro mTOR is able to phosphorylate these two regulators at comparable rates. Both (S/T)P sites,...
