What's a GeneRIF?

Saccharomyces cerevisiae alphaalpha-trehalase (ATH1) activity in soluble cell-free extracts increases after 40 degrees C adaptation but decreases when cells return to 28 degrees C. During 40 degrees C, Ath1 is confined into vesicles, avoiding the cleavage of the outside trehalose.
Title: The trehalose protective mechanism during thermal stress in Saccharomyces cerevisiae: the roles of Ath1 and Agt1.
The behaviour of trehalase mutant strains demonstrates the participation of trehalases Nth1p, Nth2p and Ath1p in the mobilization of intracellular trehalose during growth recovery after saline stress.
Title: The three trehalases Nth1p, Nth2p and Ath1p participate in the mobilization of intracellular trehalose required for recovery from saline stress in Saccharomyces cerevisiae.
hybrid Ath1 truncates fused at their C-terminus with invertase revealed that a 131 amino acid N-terminal fragment of Ath1 was sufficient to target the fusion protein to the cell surface, enabling growth of the suc2Delta mutant on sucrose
Title: The Saccharomyces cerevisiae vacuolar acid trehalase is targeted at the cell surface for its physiological function.
Gene disruption of NTH1 and ATH1 increased tolerance to freezing, heat, high-sugar and ethanol concentration.
Title: [Construction and stress tolerance of trehalase mutant in Saccharomyces cerevisiae].
The authors investigated the regulation of ATH1 transcription and found a clear involvement of the protein kinase Hog1p in the induction of this gene under severe stress conditions, such as high salt.
Title: Acid trehalase is involved in intracellular trehalose mobilization during postdiauxic growth and severe saline stress in Saccharomyces cerevisiae.
We showed that a tps1 mutant defective in the TPS catalytic subunit cultivated on trehalose, or on a dual source of carbon made of galactose and trehalose, accumulated high levels of intracellular trehalose by its Agt1p-mediated transport.
Title: New insights into trehalose metabolism by Saccharomyces cerevisiae: NTH2 encodes a functional cytosolic trehalase, and deletion of TPS1 reveals Ath1p-dependent trehalose mobilization.
Mutagenesis analyses aimed at identifying the unknown targeting signal revealed that the transmembrane domain of Ath1 contains the information sufficient for its selective sequestration into multivesicular body internal vesicles.
Title: The transmembrane domain of acid trehalase mediates ubiquitin-independent multivesicular body pathway sorting.
