Growth of Saccharomyces cerevisiae in poor nitrogen sources or exposure to the Tor inhibitor rapamycin results in expression of the nitrogen catabolite repressed (NCR) genes whose products are involved in scavenging and metabolizing nitrogen. The NCR genes are regulated by the GATA-like transactivators Gln3 and Gat1, which are thought to be under control of the rapamycin-sensitive Tor complex 1 (TORC1). We have recently shown that Gln3 nuclear translocation in response to nitrogen source quality but not in response to rapamycin requires Golgi to endosome trafficking. These and previous findings that several TORC1 components localize to low density endomembranes are discussed in a model that underscores a prominent role for the vesicular trafficking system in facilitating molecular interactions in response to nitrogen source. In addition, these findings have important implications for Tor signaling and rapamycin mechanism of action, both in yeast and in metazoans.
