Summary: Enables protein kinase activator activity. Involved in several processes, including TOR signaling; establishment or maintenance of actin cytoskeleton polarity; and mitochondria-nucleus signaling pathway. Located in Golgi membrane; endosome membrane; and nuclear periphery. Is extrinsic component of cytoplasmic side of plasma membrane. Part of TORC1 complex and TORC2 complex. Orthologous to human MLST8 (MTOR associated protein, LST8 homolog). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Aminoacyl-tRNA quality control is required for efficient activation of the TOR pathway regulator Gln3p.
Title: Aminoacyl-tRNA quality control is required for efficient activation of the TOR pathway regulator Gln3p.
We propose that Gtr1p and Gtr2p are involved in epigenetic control of gene expression in the TOR signaling pathway.
Title: Genetic evidence that Ras-like GTPases, Gtr1p, and Gtr2p, are involved in epigenetic control of gene expression in Saccharomyces cerevisiae.
Rtg1/3p, Gln3p, and Gat1p can be differentially regulated through different nutrient-sensing pathways, such as TOR and retrograde signaling, and by multiple factors, such as Lst8p, which is suggested to have a role in connecting the RTG and TOR pathways
Title: Retrograde response to mitochondrial dysfunction is separable from TOR1/2 regulation of retrograde gene expression.

Preferred Names: TOR complex subunit LST8

NP_014392.3

Subunit of TORC1 and TORC2 involved in TOR signaling; TORC1 regulates nutrient responsive growth and TORC2 regulates plasma membrane (PM) homeostasis and cell-cycle dependent actin cytoskeleton polarization; negative regulator of Rtg1p/3p and Gln3p transcription factors and amino acid biosynthesis; binds to both Tor1p and Tor2p, regulating the integrity and kinase activity of TORC2; PM retention is dependent on Avo3p; WD-repeat protein
