TOR signaling in mammals.
Central to the pathways that induce cell growth in mammals is the murine target of rapamycin (mTOR), a multi-domain, 298 kDa, evolutionarily-conserved Ser/Thr kinase that is inhibited by the drug rapamycin (Schmelzle and Hall, 2000). mTOR exerts its effects by phosphorylating eukaryotic initiation factor 4E binding protein 1 (4EBP1), which inhibits 5′-cap-dependent mRNA translation (the majorit...
متن کاملTOR regulation of AGC kinases in yeast and mammals.
The TOR (target of rapamycin), an atypical protein kinase, is evolutionarily conserved from yeast to man. Pharmacological studies using rapamycin to inhibit TOR and yeast genetic studies have provided key insights on the function of TOR in growth regulation. One of the first bona fide cellular targets of TOR was the mammalian protein kinase p70 S6K (p70 S6 kinase), a member of a family of kinas...
متن کاملTOR Signaling in Growth and Metabolism
The target of rapamycin (TOR) is a conserved Ser/Thr kinase that regulates cell growth and metabolism in response to environmental cues. Here, highlighting contributions from studies in model organisms, we review mammalian TOR complexes and the signaling branches they mediate. TOR is part of two distinct multiprotein complexes, TOR complex 1 (TORC1), which is sensitive to rapamycin, and TORC2, ...
متن کاملTOR signaling regulates microtubule structure and function
The functional diversity and structural heterogeneity of microtubules are largely determined by microtubule-associated proteins (MAPs) [1] [2]. Bik1p (bilateral karyogamy defect protein) is one of the MAPs required for microtubule assembly, stability and function in cell processes such as karyogamy and nuclear migration and positioning in the yeast Saccharomyces cerevisiae [3]. The macrocyclic ...
متن کاملParadigms of notch signaling in mammals.
Notch proteins regulate a broad spectrum of cell fate decisions and differentiation processes during fetal and postnatal life. These proteins are involved in organogenesis during embryonic development as well as in the maintenance of homeostasis of self-renewing systems. The paradigms of Notch function, such as stem and progenitor cell maintenance, lineage specification mediated by binary cell ...
