NitrogendepedentregulationofRtg1andRtg3inTORpathway

Many key signaling molecules are conserved from yeast to man. mTOR is a protein kinase involved in nutrient and growth factor signaling in humans that has a yeast homolog with a similar role, TOR1. Like its human counterpart, yeast TOR1 is also inhibited by rapamycin. Signaling downstream of the TOR kinase pathways regulates the nuclear localization of several transcription factors in response to the carbon and nitro......阅读全文
