Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including gene expression; intracellular signal transduction; and regulation of primary metabolic process. Located in bounding membrane of organelle; nucleus; and plasma membrane. Part of TORC1 complex. Used to study cancer. Human ortholog(s) of this gene implicated in autosomal dominant polycystic kidney disease; kidney angiomyolipoma; lung disease (multiple); prostate cancer; and type 2 diabetes mellitus. Orthologous to human MTOR (mechanistic target of rapamycin kinase). [provided by Alliance of Genome Resources, Dec 2024]

N- and C-terminal Gln3-Tor1 interaction sites: one acting negatively and the other positively to regulate nuclear Gln3 localization.

Sorting nexin Mdm1/SNX14 regulates nucleolar dynamics at the NVJ after TORC1 inactivation.
Title: Sorting nexin Mdm1/SNX14 regulates nucleolar dynamics at the NVJ after TORC1 inactivation.
Study found that TORC1 signaling is attenuated during ER stress and constitutive activation of TORC1 increases sensitivity to ER stressors independently of the unfolded protein response. TORC1 hyperactivation results in cell wall remodeling. Conversely, hyperactive TORC1 sensitizes cells to cell wall stressors, including the antifungal caspofungin.
Title: Hyperactive TORC1 sensitizes yeast cells to endoplasmic reticulum stress by compromising cell wall integrity.
Major Assembly Specificity domain from Tor1 is sufficient to confer stable association with TORC1-specific components.

Results showed that the 33-residue long FATC domain of yeast TOR1 or shorter fragments of it encompassing only the C-terminal 11-17 residue may be generally employed as C-terminal membrane anchoring unit for other proteins.
Title: Target of rapamycin FATC domain as a general membrane anchor: The FKBP-12 like domain of FKBP38 as a case study.
Data suggest that Pib2 functioning as a putative glutamine sensor in the regulation of TORC1.
Title: Gtr/Ego-independent TORC1 activation is achieved through a glutamine-sensitive interaction with Pib2 on the vacuolar membrane.
These results show that rapid activation of the TOR pathway by amino acids is not involved in rapid activation of the PKA pathway and that effects of Gcn2 inactivation as well as leu2 auxotrophy all act independently of the TOR pathway.
Title: The nutrient transceptor/PKA pathway functions independently of TOR and responds to leucine and Gcn2 in a TOR-independent manner.
We also show that Tor1p vacuolar localization and TORC1 anabolic functions, including growth promotion and phosphorylation of its direct substrate Sch9, are compromised in s-hhy mutants. Thus, an intact trans-Golgi and late endosome interface is a requisite for efficient Tor1 vacuolar localization and TORC1 function.
Title: Hygromycin B hypersensitive (hhy) mutants implicate an intact trans-Golgi and late endosome interface in efficient Tor1 vacuolar localization and TORC1 function.
Autophagy maintenance at homeostatic levels promoted by CR or TOR1 abrogation in syn-expressing cells was achieved by decreasing Sir2 levels and activity. Furthermore, the opposite function of Tor1 and Sir2 in autophagy is probably associated with the maintenance of autophagy activity at homeostatic levels
Title: Caloric restriction alleviates alpha-synuclein toxicity in aged yeast cells by controlling the opposite roles of Tor1 and Sir2 on autophagy.
DNA/RNA helicase Sen1 mutant causes modulation of protein-serine-threonine kinase TOR pathway and autophagy.
Title: Sen1, the homolog of human Senataxin, is critical for cell survival through regulation of redox homeostasis, mitochondrial function, and the TOR pathway in Saccharomyces cerevisiae.
