Function

SLM1_YEAST Together with SLM2, effector of the TORC2- and calcineurin-signaling pathways. Phosphorylated and activated by TORC2 under favorable growth conditions. Mediates actin polarization via inhibition of calcineurin-dependent transcription. Upon nutrient limitation or environmental stress, gets dephosphorylated by calcineurin. Dephosphorylation inhibits its interaction with TORC2, thereby antagonizing TORC2 signaling and mediating calcineurin-dependent actin depolarization. Also functions in heat-induced, calcineurin-mediated uracil permease (FUR4) endocytosis.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Protein-metabolite networks are central to biological systems, but are incompletely understood. Here, we report a screen to catalog protein-lipid interactions in yeast. We used arrays of 56 metabolites to measure lipid-binding fingerprints of 172 proteins, including 91 with predicted lipid-binding domains. We identified 530 protein-lipid associations, the majority of which are novel. To show the data set's biological value, we studied further several novel interactions with sphingolipids, a class of conserved bioactive lipids with an elusive mode of action. Integration of live-cell imaging suggests new cellular targets for these molecules, including several with pleckstrin homology (PH) domains. Validated interactions with Slm1, a regulator of actin polarization, show that PH domains can have unexpected lipid-binding specificities and can act as coincidence sensors for both phosphatidylinositol phosphates and phosphorylated sphingolipids.
