Pib2 is a cysteine sensor involved in TORC1 activation in Saccharomyces cerevisiae
Summary: Target of rapamycin complex 1 (TORC1) is a navy drapery fabric master regulator that monitors the availability of various amino acids to promote cell growth in Saccharomyces cerevisiae.It is activated via two distinct upstream pathways: the Gtr pathway, which corresponds to mammalian Rag, and the Pib2 pathway.This study shows that Ser3 was
